摘要：
The outdoor and indoor environmental gamma dose rates in air have been measured in several parts of Udupi district, Karnataka, India using thermoluminescent dosimeters (TLDs). The outdoor annual gamma dose values varies in the range 0.49-1.17 mGy/year with mean 0.75 +/- 0.18 mGy/year. Similarly indoor annual gamma dose varies in the range 0.51-1.10 mGy/year with mean 0.74 +/- 0.13 mGy/year. The mean values of indoor and outdoor gamma dose rates were 84 and 86 nGy/h respectively with indoor to outdoor dose ratio of 1.02.
