CLEAPSS Supporting practical science and technology
Welcome to the new CLEAPSS Science Website
CLEAPSS resources give teachers ideas for exciting and engaging practical activities that fire pupils' imaginations and then, unlike many other sources of ideas, go on to show teachers and technicians in detail how to translate the ideas into safe and exciting experiences in the classroom.
CLEAPSS advice and documentation is recognised by the Health and Safety Executive and the Department for Education.. (read more)

New Edition of CLEAPSS Guide L093 - Radioactives in Schools
We have issued a new edition of L093. See Guide GL114 for a list of the changes and what you need to do. 

The main reason for the new edition was the change in the Ionising Radiations Regulations which we explained in our termly bulletins and web site earlier this year.  

If your school holds the typical radioactive sources for teaching, your employer must register the work with the Health and Safety Executive. (See guide GL258.)

However, we have also been reviewing ageing sources that schools have acquired in the past. There is convincing evidence that using Becquerel plates and radium-painted timepieces of this age can no longer be justified. 

The condition has degraded to such an extent that they can no longer be regarded as safe to use. These need to be disposed of L93 gives details of disposal.
