Determination of Alpha Emitter in the Blood of the Smokers by using CR-39 (SSNTDS)


Solid state nuclear track detectors have been used to determine the distributionof various radionuclides in biological materials (smokers and nonsmokersblood persons) ; this is done by putting 10 CR-39 nuclear track detectorssheet in 5ml blood (each detector alone) sample in test tube and keptin cold region for 40 days. The CR-39 detectors then etched in 6.25N NaOHsolution for 4hours at 60 oC. Results showed that the mean track density inthe blood of the smoker's persons which is (99.4), which is higher than themean track density in the blood of the nonsmokers persons which is (78.56).
