RISK ASSESSMENT FORM
USE OF SEALED SOURCES
DEPARTMENT / UNIT
BUILDING
PERSONS INVOLVED
PROCEDURE(S) COVERED BY THIS ASSESSMENT
The purpose of this risk assessment is to restrict exposure to Users of ionising radiations and those who by
association may be exposed, e.g. co-workers, students, maintenance and cleaning staff.

Is it necessary to use a radioactive source?
no
yes
Could a sealed source of lesser energy/activity be used?
no
yes
The assessment of risks to personnel arising from ionising radiations should be based on the potential for dose before
Controls are put in place.
state the nature of the risks below e.g. finger dose:
Make an assessment of the risks:
high
medium
low
Consider, in turn, each component of the radioactive work and the Controls applicable to it, ticking any relevant Control
box. Where necessary please indicate other measures you have implemented to control the risks arising from the
work, in the space provided. The higher the risk the more stringent the Control Measure must be.
CONTROL MEASURES
Will any aspect of the work be carried out in a Controlled Area?
Will any aspect of the work be carried out in a Supervised Area?
no
no
Local Rules
I have read and will adhere to Local Rules and UCL Policy
no
yes
yes

to minimise exposure, the work area will make use of:
Work Area
delineated area / segregated from other work
shielding incorporated in the equipment
other control:
indicate which of the following will be used to minimise exposure:
The Radionuclide
perspex shielding (beta emitters)
lead shielding (gamma emitters)
PPE, i.e. disposable gloves, labcoat, glasses (delete those not used)
remote handling e.g. tongs, tweezers, tube holders
other control:
Monitoring and Personal
as a means of detecting exposure leakage or contamination the following are used:
Dosimetry
a suitable and calibrated contamination monitor, used before, during and after the work procedure
wipe tests
film badges
TLDs
all monitoring is recorded
other control:
Sealed Sources

This Section should be completed by the RPS
to ensure compliance with The Radioactive Substances Act and The Ionising Radiations
Regulations
the department/unit has registered the source with the UCL Co-ordinator for Ionising Radiations
the department/unit has the permission of the UCL Co-ordinator for Ionising Radiations to use this source
the RPS / Authorised Signatory has signed the order/transfer note
the source has a unique identification no. or distinguishing mark
other control:
Permission
as a means of minimising damage and dose the following are implemented:
The Package
the Supplier is reputable, e.g. has a quality standard
the delivery point for the sealed source is secure
the delivery point for the sealed source is adequately shielded
staff at the delivery point have received information and training in handling radionuclide packages
the package will be inspected for damage before opening
other control:
with regard to the people who may come into contact with the sealed source:
Personnel
those undertaking the work are registered radiation workers
those undertaking the work are sufficiently trained
the work poses no risk to those who may be/are pregnant
the work poses no risk to maintenance workers
the work poses no risk to non radiation workers or other members of the public
other control:
the source is stored:
Storage
in a segregated store
in a shielded store
in a locked room
incorporated in the equipment (shielded)
in an area not accessible by members of the
public, e.g. maintenance personnel
other control:
which is marked with a trefoil

DECLARATION
I the undersigned have assessed the activity and the associated risks and (delete as applicable) declare that
there is no significant risk/the risk will be controlled by the method(s) listed above. Those participating in the
work have read the assessment. The work will be reassessed whenever there is significant change and at
least annually.
