EXPLANATORY NOTE

(This note is not part of the Regulations)

These Regulations, which extend to Scotland only, amend the Radioactive Substances Act 1993 (1993 c.12) in order to implement in part the Basic Safety Standards Directive (Council Directive 96/29/Euratom) in relation to the disposal or accumulation of radioactive waste arising from clocks or watches.

Section 15 of the Radioactive Substances Act 1993 is amended so that the further exemptions from sections 13 and 14 of the Act provided for in section 15, in relation to the disposal or accumulation of radioactive waste arising from clocks or watches, are limited to circumstances-

(a) where the total radioactivity on any premises does not exceed the relevant reporting levels set out in column 2 of Table A to Annex 1 of the Directive; or

(b) where specified limits on the quantity of radioactive waste and the types of clocks and watches are met.

The levels set out in Table B of the Regulations are those allowed by The International Standard document ISO 3157:1991(E) "Radioluminescence for time measurement instruments - Specifications" a copy of which may be obtained from The Environment Protection Unit, Radioactive Waste Team, 1 J(N), Victoria Quay, Edinburgh EH6 6QQ
