§ Mr. RedmondTo ask the Secretary of State for the Environment what research his Department has carried out into Krypton 85 before authorising its release into the atmosphere in 1992; what regulations apply to Krypton 85; and if he will make a statement.
§ Mr. TrippierDischarges of radioactive gas into the atmosphere are regulated by authorisations issued under the Radioactive Substances Act 1960. My Department has supported research into immobilisation of Krypton 85 for purposes of disposal. Applicants for an authorisation are required to justify their proposals with reference to their own research results where appropriate. No application for such an authorisation to be granted in 1992 has been received. All applications are carefully assessed by Her Majesty's inspectorate of pollution before authorisations are granted.
