investigating the impact of radon therapy in water and air on the population density of stem cells

Despite the negative effects of radon on lung and skin cancers, it is possible to use radon in the treatment of skin and lung diseases as radon therapy. in this study, using mcnpx simulated dosimetry results for radon in the organs of a mird phantom, an attempt was made to investigate changes in the rate of stem cell population density. the dose rate in the air and water was calculated and incorporated into the differential equation of the stem cells, and then this equation was solved using the 4th order runge-kutta method. the results show that radon dose reduces the population density of stem cells over a period of 4 days. at the end of day 4, the stem cell density for a person in the air and water had decreased by 2.65 percent and 12.33 percent, respectively.
