Concentration, distribution and transportation of ~(222)Rn and its decay products in the environment of coastal Karnataka and Kaiga in southwest India

摘要

Studies on radon and its decay products in the atmosphere are useful for determining the radiological risk to the general public. Concentrations of ~(222)Rn and its decay products in ground level air are dependent on its exhalation rate and atmospheric diffusion depending on meteorological parameters. In the present investigation, extensive studies on ~(222)Rn exhalation rate, ~(222)Rn and its decay product concentrations in air at ambient temperature and humidity were carried out simultaneously at each sampling location in coastal Karnataka and Kaiga. Correlations of ~(226)Ra in soil, ~(222)Rn exhalation rate, equilibrium factors, and annual effective dose to the general public were estimated.
