摘要: The activity and absorbed dose rate of the naturally occurring radionuclides, viz. 238U, 232 Th 40K were determined in soil rock samples collected around Kaiga site. mean levels (Kaiga soil) are comparable with that worldwide soil, while concentrations 238U lower than those soil. outdoor air ranged 20-58 nGy . h-1 a 33.3 h-1, which is below world average 60 h-1. total effective for soils 25.6-74.4 mSv y-1 43.0 y-1. estimated at Kakrapar Rawatbhata much less coastal sites India.
