Experimental Technique to Measure Thoron Generation Rate of Building Material Samples Using RAD7 Detector [PDF]

Radiation Measurements, 2013
Thoron ( 220 Rn) is the second most abundant radon isotope in our living environment. In some dwellings it is present in significant amount which calls for its identification and remediation. Indoor thoron originates mainly from building materials. In this work we have developed and tested an experimental technique to measure thoron generation rate in ...
