A scientist from the London Borough of Islington's enviromental health department checks radiation monitoring equipment. The device on the right is a specialised Geiger counter,a device used to detect & measure ionising radiation. The apparatus is fully automatic and is set to trigger a full scale alert should the gamma ray count rise to twice that of normal background radiation. It is one of six similar units which together form a London-wide radiation monitoring scheme. The scheme,set up following the Chernobyl accident,will hopefully provide sufficient warning of the approach of nuclear fall-out to allow the successful execution of various contingency plans | |
