The amount of radioactivity of radon gas that is emitted from 10 toothpaste samples containing coal and available in the Iraqi markets was calculated, by using a CR-39 plastic organic detector. store of the samples with the CR-39 detector about time 3 month and the process of the etched by using 6.25 N of NaOH solution at temperature 85˚C for 3 hours. The results showed the maximum value concentration of Radon (222Rn) to be 103.4 Bq.m−3 in Teeth Whitening- tooth powder and the minimum concentration of Radon (222Rn) to be 15.75 in Crest- tooth paste . The mean value concentration of Radon (63.6293 Bq.m-3). All the reading obtained are within the international range, (200 Bq.m-3) as given by UNSCAR. There is no evidence of any health issues because the mean annual effective dose (1.605291 mSv/y) was below the range from 3 to 10 mSv/y according to reported of the ICRP (1993) .
