“…Our values for radium content in soil lie in the range (2.5-207.0 Bq kg −1 ) reported for Indian soils (Nageswara Rao et al 1996) using gamma ray spectrometry and are less than the permissible value (370 Bq kg −1 ), which is acceptable as safe limit (Organization for Economic Cooperation and Development 1979). These values reported for radium content in soils of study area are generally low as compared to the values reported by Sharma et al (2003) for radium concentration in soils of Kangra, Himachal Pradesh. These values of radium concentration are comparable with those reported by Singh et al (2005) for Bathinda district of Punjab.…”

The activity concentrations of soil samples collected from thirty different locations of Malwa region of Punjab were determined by 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 18.37 Bq kg(-1) (Sangrur) to 53.11 Bq kg(-1) (Sitoguno), 57.28 Bq kg(-1) (Dhanola) to 148.28 Bq kg(-1) (Sitoguno) and 211.13 Bq kg(-1) (Sunam) to 413.27 Bq kg(-1) (Virk Khera) with overall mean values of 35 Bq kg(-1), 80 Bq kg(-1)and 317 Bq kg(-1) respectively. The absorbed dose rate calculated from activity concentration of 226Ra, (232)Th and (40)K ranges between 8.47 and 24.48, 35.68 and 92.38, and 8.74 and 17.11 nGy h(-1), respectively. The total absorbed dose in the study area ranges from 58.08 nGy h(-1) to 130.85 nGy h(-1) with an average value of 79.11 nGy h(-1). The calculated values of external hazard index (H(ex)) for the soil samples of the study area range from 0.35 to 0.79. Since these values are lower than unity, therefore, according to the Radiation Protection 112 (European Commission. Radiation Protection 112, 1999) report, soil from these regions is safe and can be used as a construction material without posing any significant radiological threat to population.

“…The values of 226 Ra are comparable with those reported for the adjoining districts of the Malwa region (Mehra et al, 2007(Mehra et al, , 2009), but the values of 232 Th and 40 K are higher than those as reported by Mehra et al (2007Mehra et al ( , 2009 industrial waste from the districts that is allowed to mix in the soil, but a detailed investigation is needed for reaching this conclusion. The values reported for radium content in soils of study area are generally low as compared to the values reported by Sharma et al (2003) for radium concentration in soils of Kangra, Himachal Pradesh. Radium concentrations are comparable with those reported by Singh et al (2005) for Bathinda district of Punjab.…”

The activity concentrations of the natural radionuclides namely 238 Ra, 232 Th and 40 K are measured for soil samples collected from different locations of Faridkot and Mansa districts of Punjab. HPGe detector, based on high-resolution gamma spectrometry system is used for the measurement of activity concentration. (European Commission, 1999) report, soil from these regions is safe and can be used as construction material without posing any significant radiological threat to population. The corresponding average annual effective dose for indoor and outdoor measured in the study area are 0.42 mSv and 0.10 mSv respectively.
