HC Deb 03 March 1981 vol 1000 c72W
Mr.Skeet

asked the Secretary of State for Employment what study the Health and Safety Executive has made of the use of krypton 85 in fluorescent lamps; and whether any radiation hazard has been detected.

Mr. Waddington

When any radioactive gas is incorporated in fluorescent lamps the manufacturing process is subject to the Ionising Radiations (Unsealed Radioactive Substances) Regulations 1968. Whilst no specific study has been made, the Health and Safety Executive is satisfied that the precautionary measures required by these regulations will ensure the radiological safety of persons employed.
