| Abstract: | The diffusion
coefficient and length for some building construction materials like limestone
powder, sandstone, granite, crasher, soil, sand, cement, fly ash, gypsum, wall
putty have been calculated. The diffusion of radon gas through these materials
has been carried out under a control study. Uranium ore has been used as radon
source and LR-115 solid-state nuclear track detectors are used to record alpha
tracks due to diffusion of radon at different heights from the source. The
results indicate that the diffusion coefficient and length of radon gas in
building materials are the measure of its permeability through that medium. |
