3. Protocol.


3.1 Overview.


Work with radiois
otopes is regulated under the NSW Radiation Control Act (1990), and
Radiation Control Regulation 2003, and as described in Australian Standard 2243.4 Safety in
Laboratories Part 4: Ionizing Radiations.

Use of radioisotopes at UNSW must comply with the ab
ove regulations and also with UNSW
OHS Ionising Radiation Procedure (2007). This latter document encapsulates the NSW regulations
and interprets their practice in the specific local context.

The current document provides additional information on how thes
e regulations operate
specifically within the Lowy Cancer Research Centre.

3.2. Lowy

Radiation Safety Supervisor (Lowy RSS).


Work with radioactive substances within the Lowy Cancer Research Centre is supervised by the Lowy
Radiation Safety Supervisor. Each research centre within Lowy also has a local contact who liases
regularly with t
he Lowy RSS. All names and contact details are listed at the front of this document.


The responsibilities of the Radiation Safety Supervisor include:



• Allocation and collection of personal radiation monitors (TLD)


• Assistance in issue and renewal of

radiation licenses


• Maintaining records (see below)


• Monitoring and managing radioactive waste disposal


• Assistance in developing Standard Operating Procedures


• Identifying local radiation risk areas



Radiation Registers.

11 radiation registers a
re identified in UNSW Radiation Procedure as the requirements to be kept by
Radiation Safety Supervisors to satisfy the Radiation Control Act 1990. These registers provide an
audit trail to ensure there is an appropriate management system to control ionis
ing radiation issues.

It is the responsibility of all radiation users and laboratory managers to assist the Lowy RSS in
maintenance of these registers, by providing information as requested
.



It is therefore essential that the Lowy Radiation Safety Supervisor is kept informed of all users
and of all radiation work planned or in progress.

3.3 Definition of radioactive substance.


The NSW Radiation Control Regulation (2003) defines a radio
active substance as

“any substance which emits ionising radiation spontaneously with a specific activity greater than 100
becquerels per gram AND which contains more than the prescribed activity (40kBq, 400 kBq, 4MBq
or 40 MBq for radionuclides in Group 1,

2 3 or 4 respectively)”.


This is significant because it determines the level at which a substance is recognized officially as
radioactive and therefore subject to the relevant legislation. From our point of view, it determines
whether an individual user

is required to obtain an EPA License to Use and also if the locations where
isotopes are stored and used need to be licensed by EPA Premises Registration.


Examples of some of the more commonly used isotopes in each Group are provided in this Table.

If an individual does not
at any time

purchase, store and/or use

an amount of isotope above the
relevant limit, they do not require an EPA License to Use. However for most individual workers will it
be necessary to obtain a license.


In contrast, from a local OHS perspective, there is no lo
wer limit on the amount of a radionuclide that
is considered ‘radioactive’. Whatever the amount used at any time, all work with radioisotopes in
Lowy must comply with the UNSW OHS Ionising Radiation Procedure (2007).






9


3.4 Before you start work: Requ
irements.


There are strict legislative and OHS controls on training and supervision of staff and students
working with radioactive substances, how and where this work can take place and on who can
purchase radioactive substances. Compliance with these regulations i
s obligatory.


3.4.1 Lowy Radiation Induction Checklist


First, please complete the Lowy Radiation Induction Checklist.

The purposes of this checklist are to
inform the Lowy RSS of your intention to use isotopes, to assist you in complying with the UNS
W and
legislative requirements and planning your work and to obtain a TLD (where required).

The checklist is available electronically online (
add web site details when available
), by email from the
Lowy RSS or at the end of this document (Appendix A).

P
lease forward the completed checklist to the Lowy RSS well in advance of your anticipated
start date.



3.4.2 Training and Radiation Licenses.


All staff and students who plan to work with radioisotopes must first undergo appropriate safety
training and,
where appropriate, obtain an EPA License to Use or an Exemption Certificate.


EPA License to Use.

Staff

who work with licensable amounts of radioisotopes (see Section 4.3), or who supervise students
working with radioisotopes
must

hold a
current

EPA Lice
nse to Use. The license must specifically
state which isotopes will be used and the maximum amounts of each isotope that will be held and/or
used at any time.


To apply for an EPA Licence to Use,

contact the Lowy RSS, who will provide you with the relevant
forms and information about the additional documentation required. Evidence of completion of an
accredited training is required to obtain an EPA License to Use. The UNSW Radiation Training
Cou
rse is accredited by EPA.

An EPA License To Use
can be issued for one or three years. The current one
-
year license
application fee is
$117
and a three
-
year license application fee is
$226
. Renewal fees are currently
$67 for a single year and $176 for thr
ee years.

It is recommended that you allow up to one month to
receive your license.

10


Please note that EPA Licences to Use are issued to individuals rather than to organisations.
Therefore please notify the Lowy RSS as soon as you receive your license, s
o that the details can be
recorded in the relevant radiation registers for Lowy. This will also assist the RSS to ensure that your
license renewals are maintained and that you remain legally able to carry out ionising radiation work.


NSW Radiation Lice
nse portal.
http://www.licence.nsw.gov.au/Licence_Launchpad_RAD.htm


Radiation License Application Forms

http://www.environment.nsw.gov.au/radiation/formdownload.htm



Student Exemptio
n Certificate


Students

who work with radioisotopes
must

first attend the UNSW Radiation Training course. They
are not required to obtain an EPA License, but must be supervised by a member of staff who holds a
current License. The supervisor’s license mu
st cover the specific isotopes and amounts to be used.
A Student Exemption Certificate (
Appendix B
) must be completed and signed by the Lowy RSS and
a spreadsheet recording all students exempted displayed in the area where the student works with
isotopes.


To obtain a Student Exemption Certificate, please complete the student and supervisor sections of
the form and bring/send it to the Lowy RSS together with a copy of your Radiation Training Course
certificate and of your supervisor’s License to Use. The
form is not valid until it is countersigned by
the Lowy RSS.


The UNSW Radiation Training Course

The course is run approximately monthly by the
UNSW Radiation Health and Safety Coordinator
(Human Resources
). Details of the dates of training sessions and r
egistration are available online.

Online registration for Radiation Training Course:

http://www.hr.unsw.edu.au/ohswc/ohs/ohs_training.html


3.4.3 Planning the project.


Standard Operating Procedures and Risk Assessments.

Researchers should prepare a SOP for all work involving radioisotopes. This should be accompanied
by a risk assessment that gives consideration to the hazards (to the researcher and other workers in
the laboratory) associated with the use of radioisotopes
, in addition to other chemical and physical
hazards.

11



Project approvals.

UNSW also requires that Researchers submit a Project/ Program approval form to the Radiation
Safety Committee for their approval before any new research work involving radiation is
undertaken.
A copy of the Project/Program approval form (OHS695) is provided in
Appendix C
. The form should
be accompanied by a copy of the relevant SOP and risk assessment.

Radiation Safety Committee contacts and project submission deadlines are availa
ble online:

http://www.hr.unsw.edu.au/ohswc/ohs/ohscomm.html





3.5 Purchasing Radioisotopes.


UNSW requires that purchases of radioactive materials or radiation apparatus should be authorised
by the Lowy RSS before an order is placed. For practical pu
rposes, the Lowy RSS will delegate this
authority to the individual researcher and their Centre purchasing officer, subject to the following
conditions:

1. The responsible researcher and their Centre purchasing officer or laboratory manager are
responsible

for ensuring that the type and amount of isotope ordered is covered by the researcher’s
current EPA License to Use.

2. Students are not permitted to order isotopes; these orders must be placed by their responsible
supervisor.

3. Requisitions include the

license number of the responsible researcher or supervisor.

4. The Centre purchasing officer/laboratory manager shall keep a record of all isotope purchases
(name of researcher, EPA license number, type and amount of isotope ordered, date ordered).

5.

These records are forwarded to the Lowy RSS on a regular basis, and will be available for
inspection on request.



3.6 Record of the Storage and Use of Isotopes.


We have a legal obligation to maintain written records of the acquisition, storage, use and disposal of
radioactive isotopes. This is the responsibility of the individual licence holder.


In practice, this record can be effectively maintained by using a

log
-
book, in which a single page
records the fate of an individual bottle of isotope from the time of its arrival until its complete disposal.
A template for this is provided in
Appendix D
. You are strongly recommended to use this template or
a similar
document. All log sheets should be stored in a central location and should be held even
when the isotope is all used and disposed. The Radiation Safety Supervisor will collect copies of
these records on a regular basis.



12


3.7 Locations where isotopes ca
n be stored and used in Lowy.


3.7.1 Premises Registration

The EPA requires annual registration of laboratories where licensable amounts of radioisotopes are
stored or used. The definition of licensable amounts for the most common isotopes are shown in
S
ection 4.3.

In practice, it is likely that in most Centres that a single location/room can be used to store and use
licensable amounts of radioisotopes. Please note that Premises Registration is required even if
licensable amounts of isotopes are only pur
chased and stored (i.e. even if all experiments use sub
-
licensable amounts). Premises Registration should be arranged through the Lowy RSS.

For more information, see the relevant EPA/DECCW web site:
https://www.environment.nsw.gov.au/radiation/premises
rego.htm


3.7.2 Work with sub
-
licensable amounts of activity

Work with lesser amounts of radioisotopes can be performed in non
-
registered laboratory areas,
provided that adequate containment and shielding is provided to protect both the researcher and
oth
er workers in the area. This work should be confined to a specific designated area, which is
clearly marked and segregated from general laboratory areas. Equipment used in these areas should
also be clearly marked and should not be moved between radioact
ive and general work areas.


3.7.3 Medium Level Radioisotope laboratory.

Lowy contains one Medium level radioactive laboratory within the Centre for Vascular Research on
Level 3. This is suitable for work with larger amounts of radioisotopes, to the li
mits shown in the
following table. Access to this laboratory is available to other Lowy staff, but is restricted to registered
users. To request access and induction to this area, contact the Lowy RSS.

3.8 Working with Radioisotopes.


3.8.1
Containment.


• Work with radioactive sources must be segregated from other work. Where possible it should be
performed in a separate room; where not, a separate work area reserved for isotopes should be
identified and clearly labelled with a radiation s
ymbol.


• Work with liquid sources must be performed in a double container or a large tray (plastic or steel)
lined with absorbent paper to restrict the spread of any spilled liquid.


• All radioactive preparations should be clearly marked with the radi
ation symbol, details of the
chemical compound, radionuclide, date and name of the responsible user.


• Operations that may produce vapour, spray, dust or radioactive gas should be performed in a fume
hood or glove box.


• Where necessary, appropriate
shielding must be in place to protect both the user and other staff in
the laboratory at all times.



Gloves, labcoat, goggles and a personal dosimeter should be worn whenever radioactivity is used.
Make sure gloves are changed frequently.



Always

remove gloves before leaving the active area. Protective clothing worn in radioisotope
laboratories should be removed before leaving and left in, or immediately outside, the 'active' area.


• All reagents, apparatus and tools used in the 'active' area
must, where possible, be clearly labelled
and normally remain in the 'active' area. Where any item needs to be taken out of this area, it must
first be monitored and decontaminated where necessary. It is the responsibility of the person
removing the item

from the active area to ensure that the item is decontaminated.


• Separate waste receptacles for contaminated solid materials (e.g. gloves, paper tissues,
contaminated plastic pipette tips should be provided. They should be strong plastic lined with a
plastic bag. Where necessary, these containers must be shielded. Filled waste bags should be
sealed and labelled and disposed of as described in Section 4.9.

1
4




3.8.2 Contamination monitoring


• Routinely monitor the working area for contamination before
, during and after radioactive use. All
contaminated areas must be thoroughly decontaminated.


• Keep a
written log

of all monitoring and decontamination for each area where isotopes are used.


• Handheld monitors for detection of surface contamination by

32
P and
125
I should be used. These
must be calibrated annually. For locations and assistance with their use and maintenance, contact
your Centre local radiation contact person or Lowy RSS.



3
H,
35
S and
14
C are not easily detected with monitors. Thes
e are measured by performing a swipe
test:

Wipe area(s) and/or equipment with a small damp cloth or tissue. Ethanol swabs are useful.

Place the cloth into a scintillation vial containing scintillant (and have a background control; scintillant
only, no swi
pe). Measure radiation in a beta
-
scintillation counter.



In addition to monitoring before and after experimental procedures, it is the responsibility of the
Laboratory/Centre Manager to ensure that areas used for radioactive work are regularly monitor
ed
and written records of this monitoring are maintained.


• Workcover or EPA may ask to inspect these records.





15


3.9 Radioactive Waste Disposal


UNSW cannot dispose of licensable amounts of radioactive waste. Radioactive material must be
stored at

the University until the level of activity has decayed to sub
-
licensable levels. Minimization of
the amount and volume of radioactive waste is therefore imperative.


3.9.1 General procedures for management of radioactive waste.


• Plan for waste disposa
l before beginning any experimental work, and design experiments to

minimise the amount and volume of waste generated.


• Keep radioactive and non
-
radioactive waste separate.


• Keep individual radionuclides separate. If this is not possible, treat the com
bined waste as the more
hazardous of the radionuclides.


• Solid waste should be collected into double biohazard bags, securely taped shut, within an
appropriate shielding container.



• Liquid waste should be carefully poured into tightly screw
-
capped pla
stic bottles, within an
appropriate shielding container.


• Liquid scintillant vials and contents may be disposed together if the activity is below 100 Bq per
gram. Put vials into double biohazard bags within an appropriate shielding container.


• ALL was
te must be labeled with the following information:

Name / Laboratory/Date/Isotope/Approximate activity in Bq (1mCi = 37MBq)


• For long
-
half life isotopes (
3
H,
14
C) the total
amount of activity in any single bag or bottle must not
exceed the licensable amo
unt

for that isotope (
3
H=1mCi,
14
C=100

Ci)


• Do not store waste in the general laboratory areas. At the end of each experiment the radioactive
waste should be transferred to the Lowy radiation waste store.

16




3.9.2 Radiation waste store.


• The Lowy
radiation waste store (Room LG01) is located close to the main lifts on lower ground floor.
Access is restricted by swipe card to registered isotope users. Contact Lowy RSS if you have any
problems with access or any comments on the use and state of the
store
-
room.


• The room is monitored regularly by the Lowy Radiation Safety Assistants (names and contact details
at front of this document), who also arrange for regular collection and disposal of low
-
level waste or
transfer of
material requiring either l
ong or medium term storage to the University’s radiation store.


• All waste must be packaged in tape
-
sealed double bags, or in securely screw
-
capped plastic bottles

and fully labelled (as described above).


• All such waste must be placed into an appropr
iate waste container.


• Separate containers are provided for solid, liquid and scintillant waste. There are separate
containers provided for
3
H,
14
C ,
35
S,
125
I and
32
P.


• If you cannot find a container appropriate for your particular type of waste,

contact the Lowy
Radiation Safety Assistants or Lowy RSS.



You must complete the appropriate form for the waste container you have used for EVERY
waste deposit. These forms are in a folder in the radiation waste room.

This is a legal obligation.



If a waste container is nearly full, please ensure that you inform a Lowy Radiation Safety Assistant
or Lowy RSS, who will arrange for their disposal. Do not overfill containers.




3.9.3 Transport of radioactive waste from laboratory to the storage room

17




Before leaving the laboratory area, waste should be double
-
bagged, sealed, labelled and placed in
an appropriate shielding container (as described above).



The shielded waste should then be placed on a trolley and transported to the waste storage r
oom
via the Goods lift.



The researcher should remove lab coat and gloves before leaving the laboratory area. They should
continue to wear their TLD (where appropriate).



Clean

gloves are provided in the waste storage room, which may be used when lifting the waste
from the trolley into the appropriate container. These gloves should be removed before leaving the
room. A waste bin for the used gloves is provided.




18


3.10 Rad
ioactive Spills and Incidents.


• Working procedures and a contingency plan taking into account every radiation spill that can
reasonably be foreseen should be reviewed periodically.


• A Spill Kit should be maintained in every area/laboratory where radioactive work is carried out.
Details of the recommended contents of a Spill Kit are provided in
Appendix E.



The objectives of a cleanup procedure are:



to minimize the amount of
radioactive material entering the body



to prevent the spread of contamination from the spill area



to remove any contamination from personnel


to undertake area decontamination under qualified supervision. Inexperienced personnel
should not attempt
unsupervised decontamination.


In any case of serious injury, the person should be treated immediately, taking care to
minimize spread of contamination. Emergency treatment for life
-
threatening injury should
take precedence over treatment for contamina
tion.



3.10.1 Spill clean
-
up procedure.


Detailed procedures for spill procedures for beta (OHS303) and gamma (OHS 302) emitters are
provided in
Appendix F

and are available online at:

spills
_radiation_gamma.pdf


(i) Containment

1. Notify all persons in the room. Instruct them to move to an alternate area in the room until
surveyed for contamination.

2. Remove gloves, place absorbent pad over spill

area. Call supervisor/Radiation Safety Supervisor/
Radiation Health and Safety Coordinator, if advice/help is required.

3. Post a warning sign on the door.

4. Wait for any requested help to arrive.

19



(ii) Monitor contamination.

1. Survey all persons f
or contamination. If uncontaminated, allow them to leave.

2. Survey the spill area for the extent of contamination. Record counts on a floor plan of the area
affected.


(iii) Decontamination.

1. Apply fresh gloves and shoe covers (if necessary).

2. O
utline spill area with a grease pencil to contain liquid spread.

3. Kneeling on lined absorbent pad, using tongs and gauze, soak up liquid, working from the outside
to the centre. Blot with paper towels.

4. Monitor the area when no visible spilled mater
ial remains, to check progress of decontamination.

5. Continue decontamination as necessary to reduce the levels to <2 x background.

If necessary, apply detergent, solvent or scouring powder. Treat all materials used as contaminated
waste.

6. Monitor al
l persons involved in the decontamination process.

7. Remove all contaminated clothing and seal into plastic bags.

8. Replenish Spill Kit.


(iv) Reporting

(see Section 3.10.2)



Personal exposure


Persons who may have had an accidental intake of radio
active material should be referred to the
Radiation Health and Safety Coordinator as soon as possible for consideration of bioassay
monitoring. Where necessary, they should also be referred to a medically qualified person with
knowledge to reduce the effe
ct of, or assist elimination of, internal radioactive contamination.


In the specific instance of suspected inhalation of
125
I or
133
I, a course of iodine tablets is available
from the Radiation Safety Supervisor. This course should be commenced
immediately
, and then
further medical advice and monitoring sought.


20


Depending on the area of the body contaminated, the following procedures may be considered.

1. Wash hands with soap and water, scrubbing lightly with a soft nail brush. If necessary,
re
peat using detergent.

2. If the above does not remove contamination from the hands, wear cotton gloves covered by
tight
-
fitting rubber gloves for several hours to allow perspiration to assist removal of
contamination.

3. Rub skin other than hands with a
cotton wool pad soaked in complexing agent (e.g.
Cetavlon).

4. Wash out mouth several times with a hydrogen peroxide solution (1 tablespoon of 10
volume solution in a tumbler (~300ml) of water.

5. Irrigate eyes with saline solution (1 percent common salt

solution).


• Continue personal decontamination until monitoring shows that it has been reduced to an
acceptable level. DO NOT CONTINUE IF THERE IS A RISK OF CONTAMINATION ENTERING THE
BLOODSTREAM THROUGH BREAKS OR ABRASIONS IN THE SKIN



3.10.2 Inciden
t Reporting.


Following a radioactive spill or any other incident involving radioisotopes, Forms OHS 001 (OHS
Hazard, Incident, Injury and Illness Report Form) and OHS 005 (Radiation accident report :
supplementary form) should be completed and forwarded
to Manager, OHS&WC Unit, and copied to
Chairperson of your Workplace OHS Committee or OHS Representative, the Faculty/Divisional OHS
Coordinator and retain a copy in your School/Divisional Unit Incident Register
