Radon Measurement Techniques,nd hence the methods and instruments to measure radon activities vary widely. The measurement techniques are classified based three characteristics—i) whether measurement involves .Rn or its progeny; ii) time resolution; and iii) detection of the type of emission, whether alpha or beta particle or g

Mechanisms of Radon Emanation and Long-Term Radon Flux Studies,ades. One of the most important factors that affect the radon concentration in indoor (note that indoor air radon concentrations have direct health implications, chapter-11) and outdoor air is the rate of release of radon and its subsequent transport. The radon emanation coefficient in naturally-occ

Radon as a Tracer for Earthquake Studies,ssolution or precipitation). Its transport in subsurface environment is primarily controlled by radioactive decay, diffusion and advection. Seismic or volcanic activity in the subsurface environment results in the changes of stress-strain relationships of the subsurface material affecting the precur
