Over the next few weeks you may notice some radon dosimeters in some of the popular group caves. We are undertaking a 5 year re-sample of the group caves to update the figures for the BCA Radon Underground work. Please do not fiddle or tamper with the meters. If you have any questions please get in touch with Tom Partridge – tompartridge@ymail.com. Thanks!
