A 'delayed' counting method to determine indoor Rn-222 levels indirectly
Description
A new indirect and 'delayed' way is presented to determine indoor concentration of Rn-222 by best-fitting methods. If a rapid knowledge of Rn-222 levels is required and if a detection system is not available in situ, it is possible to obtain concentration of radioactive gas by determining of 'delayed' counts of Po-214. The 'delay' time consists of two or three hours. The method is based on the use of cellulose filters for particulate collection and on the analysis of samples by alpha spectroscopy. It is also possible to obtain concentrations of short-lived radon daughters Po-218, Pb-214, Bi-214, which are very important quantities in a medical framework
