“…The average annual exposure to radon and decay products in the Godavarikhani twoincline mine is estimated as 0.26 WLM (working level month). This value establishes that the concentration of radon and its progeny levels are consistent with other mines in the world [15][16][17][18][19][20].…”

In India, out of about 0.7 million miners, nearly 0.5 million persons are directly engaged in coal operations. Radon and its progeny levels have been quantified in the coal-mining environment of Godavarikhani, Andhra Pradesh, India using solid-state nuclear track detectors. Seasonal and mine depth variations in radon levels have been recorded resulting in the identification of locations with a high radon level as areas with no mining activity, active mining operational zones and return air ventilation paths. All these radon levels were below the permissible levels. The average concentrations of radon and its progeny levels were found to be 144 +/- 61 Bq m(-3) and 20 +/- 11 mWL (working level) respectively in the two-incline mine, and these values for the five-incline mine are recorded as 315 +/- 71 Bq m(-3) and 30 +/- 9 mWL respectively.

“…This is mainly related to the potential energy of the alpha particles emitted by polonium radioisotopes. This method is employed to investigate the degree of exposure to short-lived radon progeny in mining [ 12 ]. It allows us to estimate the likelihood of lung cancer development in miners.…”

Radon is a carcinogenic factor, but the effects of the potential carcinogenicity of radon progeny on the human body during the prenatal period have not yet been explored. Based on data regarding the half-lives of radon-222 and radon-220 and their progeny, this paper considers their potential effects on the human body in the prenatal period. Radon-220 represents a small fraction of the total radon concentration in the air, but the dose of radon-220 progeny may have a significant effect in the prenatal period, as the precursors of polonium-212 exhibit substantially longer half-lives than the corresponding precursors of polonium-214. Theoretically, it is possible that radon-220 decay products, particularly polonium-212, are the predominant emitters of alpha particles in the prenatal period. Studies aiming to establish a relationship between exposure to radon during pregnancy and the subsequently observed incidence of childhood neoplasms should consider this observation.

“…For instance, the relatively high residual cancer rates for males in the most industrialized and polluted southern voivodships, and their absence among women, may be indicative of a significant role played there by concurrent exposure to occupational and environmental carcinogens, possibly acting synergistically. High occupational exposures among men to chemical carcinogens and radon in this region, which is characterized by a high density of mines, smelters, coke ovens, and steel mills, have been well documented (3,33). The putative contribution of occupational factors to the observed distribution of residual cancer rates is also consistent with the high residual rates in some northern voivodships, which, though not characterized by the mining, smelting, or coalprocessing industries, have been the center of the ship-building industry, with its attendant occupational asbestos exposures.…”
