Study on the measurement of background radiation level in and around Bharati station, Larsemann Hills region of East Antarctica was taken up using different types of detectors. The radiation levels due to cosmogenic (especially neutron) and terrestrial origin (gamma and neutron) and natural radioactivity due to presence of primordial radionuclide in the samples of soil, rock, lake water, ice and air were measured. The data on radionuclide activities of soil and lake water are presented pictorially using surfer plot. The study was further extended to the in-situ measurement of Radon/Thoron concentration in soil pores. Measurement of gross alpha and beta activity in air samples was also carried out. These studies were conducted during several Indian Scientific Expeditions to Antarctica (ISEA) (32nd to 36th) for the period from 2012 to 2017. Some of the data generated during the above mentioned expeditions are already published previously and hence mentioned very briefly in the text whereas the unpublished data are presented and discussed in this article for the first time.

使用不同类型的探测器对东南极洲拉斯曼山地区巴拉蒂站及其周围背景辐射水平的测量进行了研究。测量了宇宙源（特别是中子）和陆地源（伽马和中子）引起的辐射水平以及由于土壤、岩石、湖水、冰和空气样本中存在原始放射性核素而产生的自然放射性。使用冲浪者图以图形方式呈现土壤和湖水放射性核素活度的数据。该研究进一步扩展到土壤孔隙中氡气/钍气浓度的原位测量。还对空气样品中的总α和β活性进行了测量。这些研究是在 2012 年至 2017 年期间的几次印度南极洲科学考察 (ISEA)（第 32 次至第 36 次）期间进行的。上述考察期间产生的一些数据之前已经发表，因此在文本中非常简短地提及，而本文首次介绍和讨论未发表的数据。
