# The Radioactive Substances (Substances of Low Activity) Exemption Order 1986, Note: Explanatory note


This order, which extends to England, Wales and Scotland, is concerned with exemptions and exclusions under the Radioactive Substances Act 1960 in respect of certain substances of low radioactivity.
Article 2 exempts persons unconditionally from registration under section 1 of the Act in respect of the keeping and use on any premises of such substances.
Article 3 excludes from section 6(1) and (3) of the Act (control on the disposal of radioactive waste) the disposal of—
(a) solid waste, other than closed sources, in which the activity does not exceed 0.4 becquerels per gram;
(b) organic liquid waste whose only radioactive content is carbon 14 or tritium, or both, in which the activity does not exceed 0.4 becquerels per millilitre; and
(c) gases with a half life not exceeding 100 seconds.
This order revokes the orders mentioned in Schedule 2.
Measurements of radioactivity which formerly were specified in curies are now specified in becquerels, following the adoption of the International System of Units (SI Units). 0.37 becquerels are approximately equivalent to 10>−5> micro curies.
