英文摘要: Abstract(#br)The analysis of naturally occurring radionuclides ( 226 Ra, 232 Th and 40 K) has been carried out in soil samples collected from oil and gas field environment of Delta state, using gamma spectroscopy operated on a Canberra vertical high purity 2″×2″ NaI(TI) detector. The activity concentration of the samples ranges from 19.2 ± 5.6Bqkg −1 to 94.2 ± 7.7Bqkg −1 with mean value of 41.0 ± 5.0Bqkg −1 for 226 Ra, 17.1 ± 3.0Bqkg −1 to 47.5 ± 5.3Bqkg −1 with mean value of 29.7 ± 4Bqkg −1 for 232 Th and 107.0 ± 10.2Bqkg −1 to 712.4 ± 38.9Bqkg −1 with a mean value of 412.5 ± 20.0Bqkg...
