ABSTRACT As part of an ongoing project to assess the population dose from indoor radon and its daughters in India, a set of parallel measurements was made in more than 150 houses of different types to estimate indoor radon and progeny levels. Time-integrated solid state nuclear track detectors were employed for the measurement of radon concentration and potential alpha energy exposure level. From these values the equilibrium factor (F) between radon and its progeny was estimated for each house. An average F value of 0.39 was obtained.

    ABSTRACT: This paper reports the results of the second interlaboratory calibration experiments, which were carried out in two parts. In the first, five types of commercially available and economically cheap membranes were tested as the barrier against thoron for “radon-only” measurements. It was found that all the membranes tested are good barriers against thoron and can be used in the “radon-only” device. In the second, actual calibration experiments were performed with LR-115 type-II and CR-39 track-etch detectors for different radon measuring configurations in a radon exposure chamber.

    ABSTRACT: In the present paper, the results of radon activity recorded in domestic regions of the Kulu area (Himachal Pradesh, India) known for uranium mineralisation are reported. Time integrated track etch technique has been used for the measurement of indoor radon levels. Bare cellulose nitrate LR-115 type II films have been used as detectors in the survey of radon. The calibration constant of per WL of radon at equilibrium (which corresponds to per ) determined by Subba Ramu et al. (Sci. Total Environ. 73 (1988) 245) has been used to express radon activity in . In some of the dwellings the levels of radon activity are found to be quite high giving an annual exposure dose that crosses the safety limits set by the International Commission on Radiological Protection (ICRP, Protection against radon-222 at home and at work, ICRP Publication 65, Annals of the ICRP, 23 (2), 1993). A study of seasonal variations of indoor radon in some of the dwellings has also been carried out.

    ABSTRACT: Coal contains naturally occurring radionuclides arising from the uranium and thorium series. Burning of coal is one of the sources of the technologically enhanced exposure of human beings from natural radionuclides. The population is exposed to radiation which are discharged to the environment by the emissions from thermal power stations in gaseous and particulate form containing radioisotopes. This paper presents the measurements of airborne radon levels in the coal fired thermal power plants at Kasimpur (Uttar Pradesh), Lahra Mohabat at Bhatinda (Punjab) and at Durgapur (West Bengal) in India. Radon levels in the plants are found to be higher than in the Indian dwellings. Potential alpha activity, radon and its daughter concentration, and effective dose equivalent are obtained.
