SCHEDULE 23Radioactive substances activities

PART 4The Basic Safety Standards Directive

SECTION 1Exposures and doses

Optimisation and dose limits1

In respect of a radioactive substances activity that relates to radioactive waste, the regulator must exercise its relevant functions to ensure that—

a

all exposures to ionising radiation of any member of the public and of the population as a whole resulting from the disposal of radioactive waste are kept as low as reasonably achievable, taking into account economic and social factors, and

b

the sum of the doses resulting from the exposure of any member of the public to ionising radiation does not exceed the dose limits set out in F1Article 12 of the Basic Safety Standards Directive subject to the exclusions set out in F3Article 5(c) of that Directive.

Specific dose limits and calculation2

1

In exercising those relevant functions in relation to the planning stage of radiation protection, the regulator must have regard to the following maximum doses to individuals which may result from a defined source—

a

0.3 millisieverts per year from any sourceF2..., or

b

0.5 millisieverts per year from the discharges from any single site.

F42

In exercising those relevant functions, the regulator must observe the requirements of the following provisions—

a

when estimating effective dose and equivalent dose—

i

from external exposure, chapters 4 and 5 of International Commission on Radiological Protection Publication 116; and

ii

from internal exposure, chapter 1 of International Commission on Radiological Protection Publication 119; and

b

in estimating population doses, Article 66 of the Basic Safety Standards Directive.
