Measurement of Radon-222 exhalation rate in different kinds tablet medicine samplesby Detectors CR-39

Abstract

Radon-222 concentration is indicated to the uranium in medicines and the amount of uranium in medicines can damage human’s kidneys by preventing normal elimination of urea and other waste products. We measured the radon gas concentration in twenty types of medicine samples as a tablet different in origin{ (IRAQI - BAGHDAD ) , ( IRAQI – SAFA) ,) IRAQI-NINAWA(, and (IRAQI - SAMARA ) } by using alpha-emitters registrations which are emitted from radon gas in (CR-39) nuclear track detector. A number of the detectors were used with dimensions of 1x1 cm2 and with exposure time of 60 days. The detectors collected and chemically treated . we found that the radon levels in medicine samples range from (0.0077-2.1) Bq/mg.
