Preliminary investigation of radon-222 flux density in the soil surface: a case study of campus, China

AbstractRadon-222 (222Rn) is a global indoor health issue. A total of 74 points were measured in the woodland and grassland with the RAD7 device on the Hongxiang Campus of the University of South China. The results showed that the222Rn flux (RF) was 39.0 ± 30.3 mBq m−2 s−1 and 39.7 ± 29.3 mBq m−2 s−1 in the woodland and grassland, respectively. The value of RF map was lower than 50 mBq m−2 s−1 in most campus areas. The results serve as essential reference data for future222Rn risk-health assessment and management strategies on the campus.
