Abstract: A national survey of the natural background gamma radiationlevels has been concluded on 214 locations making use ofmailed TLDs. Radiation monitoring has been done on a quarterlybasis over one full year at each location and eachmeasurement comprising of two evaluations. The salient resultsare:1) While the air-kerma levels follow a log normal distribution,the population-weighted state averages are distributednormally.2) After nationally taking into account the house shieldingand hause occupancy factors and body attenuations, the meannatural radiation per caput DE for the country works out tobe 690 ± 200 $\mu$Sv • y$^{-1}$ (range 285 - 1065).3) The application of the traditionally employedradiocarcinogenic risk factor would indicate that hardly2 % of the total cancer fatali ties occuring annually inIndia could be related to the environmental radiation.4) An attempt to correlate the distribution patterns of theradiation levels and the cancer rates (as reported by theNational Cancer Registry) resulted in an inverse correlation:where the radiation level is high, cancer risk ininvariably low.
