Abstract

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) (32^nd to 36^th) 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above mentioned expeditions are already published previously and hence mentioned very briefly in the text whereas the unpublished data are presented and discussed in this article for the first time.

南极洲东部拉尔斯曼山巴拉蒂站周围本底辐射水平和环境放射性调查--概述

使用不同类型的探测器对南极洲东部拉尔斯曼山地区巴拉蒂站及其周围的本底辐射水平进行了测量。测量了土壤、岩石、湖水、冰和空气样本中宇宙源（特别是中子）和陆地源（伽马射线和中子）造成的辐射水平，以及原始放射性核素存在造成的天然放射性水平。土壤和湖水中放射性核素活度的数据用冲浪者图来表示。研究还进一步扩展到对土壤孔隙中氡/钍浓度的原位测量。还对空气样本中的α和β总活度进行了测量。这些研究是在 2012 年至 2017 年期间多次印度南极洲科学考察（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已在之前发表，因此在文中简要提及，而未发表的数据则在本文中首次介绍和讨论。

期刊介绍： Polar Science is an international, peer-reviewed quarterly journal. It is dedicated to publishing original research articles for sciences relating to the polar regions of the Earth and other planets. Polar Science aims to cover 15 disciplines which are listed below; they cover most aspects of physical sciences, geosciences and life sciences, together with engineering and social sciences. Articles should attract the interest of broad polar science communities, and not be limited to the interests of those who work under specific research subjects. Polar Science also has an Open Archive whereby published articles are made freely available from ScienceDirect after an embargo period of 24 months from the date of publication. - Space and upper atmosphere physics - Atmospheric science/climatology - Glaciology - Oceanography/sea ice studies - Geology/petrology - Solid earth geophysics/seismology - Marine Earth science - Geomorphology/Cenozoic-Quaternary geology - Meteoritics - Terrestrial biology - Marine biology - Animal ecology - Environment - Polar Engineering - Humanities and social sciences.
