The objective of the study was to find the significant impact of season on the outdoor gamma dose rate including statistical analysis. Outdoor gamma dose rates were studied for 52 locations of the Balod district, Chhattisgarh, India, in summer and winter. Statistical analysis confirmed that there was no significant difference in dose rate between summer and winter. Geology of the area was the most important factor, and meteorological parameters had less influence; consequently, in this investigation, the impact of these parameters were checked through linear regression, cluster, principal component and factor analysis.

影响室外伽马剂量率和季节影响因素的统计研究

该研究的目的是找出季节对室外伽马剂量率的显着影响，包括统计分析。在夏季和冬季，研究了印度恰蒂斯加尔邦 Balod 区的 52 个地点的室外伽马剂量率。统计分析证实，夏季和冬季的剂量率没有显着差异。该地区的地质是最重要的因素，气象参数的影响较小；因此，在本次调查中，通过线性回归、聚类、主成分和因子分析来检查这些参数的影响。
