英文摘要: Kerala is listed among the six highest background radiation areas of the world. The west coast of Kerala is very well studied. However, no data is available regarding the high ranges. This study reports measurement of terrestrial concentration of radionuclides in Wayanad district (altitude range 700–2100 m above mean sea level), a known tourist place of Kerala, India having a sizeable tribal population. Activities of 40K, 226Ra and 232Th in soil samples measured using gamma ray spectrometry were found to be 265 ± 334, 21 ± 15 and 39 ± 38 Bq kg−1 respectively. Similar studies were done for rock samples. The average indoor and outdoor hazard indices were found to be 0.24 and 0.20 for soil and 0.5 and 0.4 for rocks, respectively. The indoor radon...
