The present study attempts to provide a proper explanation to define the monazite source region and reason for its enrichment in coastal belts of Kollam district, Kerala. As part of that, primary data on enrichment of naturally occurring radionuclides viz. 40 K, 226 Ra, and 232 Th in sand samples were collected from the study area and has been measured using NaI(Tl) detector. The radiological parameters were also calculated and compared with the Indian and World average values suggested by the UNSCEAR. The local variations in enrichment then connected with local lithology, drainage and sea wave direction for understanding the source and path of distribution. Connecting the dynamics of radioactivity concentration in a Geospatial study had finally provided details on source and locations of the parent material.

喀拉拉邦科拉姆区高本底辐射区独居石斑块来源和放射性核素浓度动态

本研究试图为定义独居石源区及其在喀拉拉邦 Kollam 区沿海带富集的原因提供适当的解释。作为其中的一部分，关于天然存在的放射性核素富集的原始数据即。40 K、226 Ra 和 232 Th 从研究区收集并使用 NaI(Tl) 检测器进行了测量。还计算了放射学参数，并与 UNSCEAR 建议的印度和世界平均值进行了比较。然后将局部富集变化与当地岩性、排水和海浪方向联系起来，以了解分布的来源和路径。在地理空间研究中连接放射性浓度的动态最终提供了有关母体材料来源和位置的详细信息。
