Abstract

This study presents a comprehensive assessment of atmospheric particulate radioactivity in Trombay, Mumbai, conducted from 2016 to 2022. Particulate samples were collected using high volume samplers and analysed for gross α and β activities. Average activities were 0.19 ± 0.11 and 1.77 ± 0.86 mBq m⁻³, respectively. A positive correlation (r² = 0.37; Spearman coefficient = 0.66) indicated common or related sources. The mean α/β ratio was 0.11 ± 0.05. Seasonal trends showed elevated activity in winter. However, no statistically significant change in average activity was observed over time. The findings suggest stable natural sources dominate atmospheric radioactivity, with variations influenced by seasonal and meteorological conditions.

孟买特罗姆贝地区空气颗粒物中总α和总β活性的评价

本研究对2016年至2022年孟买特罗姆贝的大气颗粒放射性进行了全面评估。采用大体积采样器采集颗粒样品，分析总α和β活性。平均活度分别为0.19±0.11和1.77±0.86 mBq m−3。正相关（r2 = 0.37； Spearman系数= 0.66）表明有共同或相关的来源。平均α/β比值为0.11±0.05。季节性趋势显示，冬季活动增加。然而，随着时间的推移，平均活动量没有统计学上的显著变化。研究结果表明，稳定的自然来源主导着大气放射性，其变化受季节和气象条件的影响。
