The specific activity of naturally occurring radioactive materials and (137)Cs in surface soils around the new Bhabha Atomic Research Centre site at Visakhapatnam region, Eastern India, has been determined using high-resolution gamma-ray spectrometry as part of a baseline radiological survey. Radiation hazard for the samples was assessed by radium equivalent activity (Raeq) and absorbed gamma dose rate (D). The mean absorbed gamma dose rate was found to be 104.9 nGy h(-1). The average annual effective dose equivalent was found to be 0.13 mSv y(-1).
作为基线放射学调查的一部分，利用高分辨率伽马射线能谱法测定了印度东部维沙卡帕特南地区新巴巴原子研究中心场地周围表层土壤中天然存在的放射性物质及（137）铯的比活度。通过镭当量活度（Raeq）和吸收伽马剂量率（D）对样品的辐射危害进行了评估。发现平均吸收伽马剂量率为104.9纳戈瑞每小时（nGy h(-1)）。发现平均年有效剂量当量为0.13毫希沃特每年（mSv y(-1)）。
