A study of indoor radon, thoron and their progeny measurement in Tosham region Haryana, India
In the present study indoor radon, thoron and their decay products concentrations have been measured using the newly developed LR-115 type-ІІ based Radon-Thoron discriminating twin-cup dosimeters with single entry face, direct radon and thoron progeny sensors (DRPS/DTPS) respectively. The annual ann...
