Abstract: | It has been established that radon and its airborne decay products can present serious radiation hazards. A long term exposure
to high concentration of radon causes lung cancer. Besides, it is also known that out of the total radiation dose received
from natural and man-made sources, 60% of the dose is due to radon and its progeny. Taking this into account, an attempt has
been made to estimate radon concentration in dwellings in and around Guwahati using aluminium dosimeter cups with CR-39 plastic
detectors. Results of preliminary investigation presented in this paper show that the mean concentration is 21.31 Bq m − 3. |
