requirements
Some of the major considerations are:

notifi cation to HSE of specifi c work unless specifi ed
in schedule 1 to the regulations (Regulation 6)
➤
carrying out prior risk assessment by a radi
-
ation employer before commencing a new activity
(Regulation 7)
➤
use of personal protective equipment (Regulation 9)
➤
maintenance and examination of engineering con-
trols and PPE (Regulation 10)
➤
dose limitations (Regulation 11)
➤
contingency plans for emergencies (Regulation 12)
➤
radiation protection adviser appointment (Regula
-
tion 13)
➤
information instruction and training (Regulation 14).
17.20.6 Prior risk assessment
Where a radiation employer is required to undertake a
prior
risk assessment, the following matters need to be
considered, where they are relevant:
➤
the nature of the sources of ionizing radiation to be
used, or likely to be present, including accumulation
of radon in the working environment
➤
estimated radiation dose rates to which anyone can
be
exposed
➤
the likelihood of contamination arising and being
spread
➤
the results of any previous personal dosimetry or
area monitoring relevant to the proposed work
➤
advice from the manufacturer or supplier of equip-
ment about its safe use and maintenance
➤
engineering control measures and design features
already
in place or planned
➤
any planned systems of work; estimated levels of
airborne and surface contamination likely to be
encountered
➤
the effectiveness and the suitability of personal pro-
tective equipment to be provided
➤
the extent of unrestricted access to working areas
where dose rates or contamination
levels are likely
to be signifi cant; possible accident situations, their
likelihood and potential severity
➤
the consequences of possible failures of control
measures – such as electrical interlocks, ventilation
systems and warning devices –
or systems of work;
steps to prevent identifi ed accident situations, or
limit their consequences.
This prior risk assessment should enable the employer
to determine:
➤
what action is needed to ensure that the radiation
exposure of all persons is kept as low as reasonably
practicable (Regulation 8 (1))
➤
what steps are necessary to achieve this control
of exposure by the use of engineering controls,
design
features, safety devices and warning devices
(Regulation 8 (2) (a)) and, in addition, by the develop-
ment of systems of work (Regulation 8 (2) (b))
➤
whether it is appropriate to provide personal pro-
tective equipment and if so what type would be
adequate and suitable (Regulation 8 (2) (c))
➤
whether it is appropriate to establish any dose con-
straints for
planning or design purposes, and if so
what values should be used (Regulation 8 (3))
➤
the need to alter the working conditions of any female
employee who declares she is pregnant or is breast-
feeding (Regulation 8 (5))
➤
an appropriate investigation level to check that
expos ures are being restricted as far as reasonably
practicable (Regulation 8 (7))
➤
what maintenance and testing schedules are required
for the control measures selected (Regulation 10)
➤
what contingency plans
are necessary to address
reasonably foreseeable accidents (Regulation 12)
➤
the training needs of classifi ed and non-classifi ed
employees (Regulation 14)
➤
the need to designate specifi c areas as controlled or
supervised areas and to specify local rules (Regula-
tions 16 and 17)
➤
the actions needed to ensure restriction of access
and other specifi c measures in controlled or super-
vised areas (Regulation 18)
➤
the need to designate certain employees as classi-
fi ed persons (Regulation 20)
➤
the content of a suitable programme of dose assess-
ment for employees designated as classifi ed persons
and for others who enter controlled areas (Regula-
tions 18 and 21)
➤
the responsibilities of managers
for ensuring compli-
ance with these Regulations
➤
an appropriate programme of monitoring or auditing
of arrangements to check that the requirements of
these Regulations are being met.
