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)

Changes to the ionising radiation regulations - Latest Update - 09/01/184 Jan 2018
The regulations controlling the use of radioactive materials are changing in January 2018. 

This change will affect education employers. The radioactive sources typically used in school-science fall into the 'medium risk band' and consequently education employers with these sources will be required to register with the health and safety regulator (HSENI for NI, HSE for the rest of the UK). 

The notification from the current regulations cannot be carried over - a new registration is required.

Please note this is a new system and as such it is a changing situation. Please check back regularly for updates about how to register.

We have created a how to register guide, which you can access here.

Now with added information for schools in Northern Ireland.

To find out if you are in a high Radon area, please use this map.
