Determination the concentrations of radon gas and exhalation rate in some phosphate fertilizer using CR-39 track detector

Abstract

The aim of this research is to measure the concentrations of radon gas for nine kinds of imported fertilizers samples that are widely used due to what they can cause of an increment in natural radioactive level of soil, and that will affect the increase in the environmental contamination level with radiation.The results of the research show, the concentrations of radon gasCRn ranges from 161.9-251.98 Bqm-3 with the average value 208.01±32.8 Bqm-3, the surface exhalation rates for radon gas
