A national survey of background $\alpha$-particle radioactivity

Abstract

This survey evolved from our use of TASTRAK plastic in schools for teaching radioactivity. From this point of view the survey has been extremely successful. It is the first time that α-radiation has been monitored by school children, giving a national picture. The data have revealed many interesting features of the pattern of α-activity and radon emission from the ground in the UK. The survey clearly needed to be repeated with a much larger sample and this is now in progress. In particular, we hope to obtain much more data from Cornwall, Devon and Somerset where indoor radon levels in houses are known to be high. The timing has been adjusted so that schools in Scotland can take part.
