Paragraph 26 General Principles of Radiological Protection: Optimisation and Dose LimitationF3

(1)

SEPA must exercise its relevant functions in relation to radioactive substances activities to ensure that the radiation protection of individuals subject to public exposures is optimised.

(2)

SEPA must exercise its relevant functions in relation to radioactive substances activities to ensure that the sum of doses to an individual F1member of the public does not exceed—

(a)

an effective dose of 1 millisievert in a year;

(b)

an equivalent dose for the lens of the eye of 15 millisieverts in a year;

(c)

an equivalent dose for the skin of 50 millisieverts in a year, averaged over any 1 cm² of skin regardless of the area exposed.

(3)

In these Regulations, “effective dose” and “equivalent dose” have the same meaning as in the Basic Safety Standards Directive.

(4)

In order to estimate effective and equivalent doses, SEPA must use the values and relationships recommended in—

F2(a)

ICRP publication 144: Dose Coefficients for External Exposures to Environmental Sources

(b)

chapter 1 of ICRP Publication 119 M1 for the estimation of doses from internal exposure.
