Since the discovery in 1958, Solid State Nuclear Track Detectors (SSNTD) found promising application in the various field. With the demanding interest on the work of radon and products of it, as a source of exposure to radiation, the estimation of concentration of radon in various parts of the India has been realized. Radon and its decay products inhalation is one the major source of the radioactive dose in taken by the human population from natural radiation. The epidemiological studies have established the fact that radon and its progeny are associated with lung cancer. Track detectors were used for estimating Radon and Thoron gas concentration levels in the dwellings of different parts of India. In this review the relation among building materials, insulation systems, and indoor radon pollution has been studied.
