Assessment of dose rates around Manisa (Turkey)

Indoor radon concentration levels, gamma dose rates and impact of geology – A case study in Kotli, State of Azad Jammu and Kashmir, sub-Himalayas, in Pakistan

“…The gamma dose rates recorded indoors were 35% higher than in the outdoor environs. The range of indoor gamma dose rates obtained in the present study in Kotli was similar to the 113.1 to 243.6 nGy.h -1 for Manisa, Turkey (Erees et al,2005) and lies towards the higher side compared with studies reported for the Kastamonu region, Nothern Turkey (44.9 to 68.5 nGy.h -1 , Kam and Bozkurt, 2007) and Tekirdag, Turkey (30.5 to 68.6 nGy.h -1 , Yarar and Kam, 2005). However, the indoor gamma dose rate range of (104 to 165) nGy.h -1 in the Kotli area is appreciably higher than the world estimates for the population-weighted average range of 18 to 93 nGy.h -1 , UNSCEAR (2000).…”

Indoor radon concentration, outdoor gamma dose rates and impact of geology in the Dhirkot area, Azad Jammu and Kashmir, sub-Himalayas, Pakistan

“…However, in Lahore, Pakistan, at lower altitude (800 feet), the average gamma dose rate has been reported as 65 nGy/h (Akhtar et al, 2005). The outdoor gamma dose rates in Turkey (Erees et al, 2006) and Japan (Chikasawa et al, 2001) have been reported to range from 78.3 nGy/h to 135.7 nGy/h and 13.8 nGy/h to 187 nGy/h, respectively. The 69.6 ± 2.2 nGy/h to 113.1 ± 2.4 nGy/h gamma dose rate in the area is within the gamma dose rates of the above-mentioned countries.…”
