| Abstract: | The activity
concentrations and the gamma absorbed dose rates of radio nuclides in soil
samples collected from different locations of Hisar district of Haryana have
been determined for the first time using HPGe detector based on high-resolution
gamma spectrometry system. The range of activity concentrations of 226Ra,
232Th and 40K in the soil from the studied areas varies
from 13.37 (Ganguwa) to 21.43 Bq kg-1 (Kheri), 34.67 (Nehla) to 54.43 Bq
kg-1
(Ganguwa) and 298.78 (Dhansu) to 398.78 Bq kg-1 (Nehla) with overall
mean values of 17.79, 45.45 and 359.96 Bq kg-1, respectively. The absorbed dose
rate calculated from activity concentration of 226Ra, 234Th
and 40K ranges between 6.16 and 9.88, 21.6 and 33.91, and 12.37 and
16.51 nGy h-1,
respectively. The total absorbed dose in the study area ranges from 45.83 to
57.15 nGy h-1 with an
average value of 51.42 nGy h-1. The calculated values of external hazard index (Hex) for the soil samples of the study area range from 0.26
to 0.33, which is less than unity. |
