Passive detector for measurement of the implanted /sup 210/Po activity in glass

It is a well known fact that radon is the most important factor in the natural radiation background. For complete dose calculations we need information about the radon concentration up to 25 years ago. As suggested by C. Samuelsson et al.

Description
Summary:It is a well known fact that radon is the most important factor in the natural radiation background. For complete dose calculations we need information about the radon concentration up to 25 years ago. As suggested by C. Samuelsson et al. (1988), the activity of the implanted radon daughter /sup 210/Po can be used to reconstruct radon activity over past decades. For large scale surveys in dwellings a passive detector based on polycarbonate foils has been investigated. This system has a sufficient sensitivity to detect /sup 210/Po levels down to 1 Bq/m/sup 2/ with a 6 month measuring period.< >
