摘　　要：Objective:To investigate radon emanation in geothermal manifestations around Mount Tampomas,West Java,Indonesia,and assess radon concentrations in soil and water samples.Methods:Radon measurements were conducted using the Durridge Rad7 instrument,supplemented with a soil gas probe for in-situ soil radon measurements at a depth of 80 cm.In-situ water radon measurements were performed using the Rad Aqua instrument,while radon measurements for hot water samples were conducted separately.Radon measurements for hot water samples were corrected for decay using a radon decay correction factor.Results:The analysis of radon measurements revealed a wide range of concentrations in soil and water samples.Soil radon concentrations ranged from 15 Bq/m^(3) to 4,660 Bq/m^(3),with localized hotspots exhibiting exceptionally high concentrations.Water radon measurements showed elevated levels,ranging from 0.2 Bq/L to 13.4 Bq/L insitu,particularly in hot springs.In collected water samples,radon concentrations ranged from 1 Bq/L to 6 Bq/L.These combined results highlight significant variability in radon levels across different water sources influenced by geothermal activity.Conclusions:These findings indicate active emanation processes influenced by geological factors and underscore the role of subsurface geology and aquifer characteristics in radon transport mechanisms.The presence of localized radon hotspots suggests the need for comprehensive monitoring and proactive management strategies to mitigate environmental and public health risks associated with radon exposure.
