Deduction of Radon Diffusion Process from Natural Radioactive Porous Samples Collected from Sinai-Egypt
Keywords:Radon, HPGe, SSNTD CR-39, Radon diffusion, Radium content
This work develops a straightforward investigation method for estimating the behaviour of radon diffusion from natural radioactive sample content a radium activity to sample surfaces. In the current inquiry, a dual approach is adopted. First, the HPGe detector was used to measure the radium activity concentration, and the radon activity corresponding to the measured radium content was computed. Second, the (SSNTD) CR-39 accumulation chamber was used to record the radon activity emanating from natural materials. Finally, a comparison of the results from the two approaches demonstrates that leakage and diffusion processes cause the real radon in any sample to be more than the radon that has been detected. The impact of sample layer thickness on radon detection has been studied, and the findings indicate that maximum radon measurement is more effectively accomplished at layer thicknesses of 50 mm.
