Abstract

Abstract:

In order to study the regional mapping method of radon concentration in soils, the survey work was performed in a total survey area of 1,800 km2 in Zhongshan, Guangdong Province. The electronic radon monitor RAD7 and the permeameter RADON JOK were used to measure radon222 concentration and gas permeability of soils, acquiring 67 valid data. The radon 222 concentrations of soils in Zhongshan vary between 0.74 kBq/m3 and 1,199.24 kBq/m3, and the average concentration is (100.41±154.64) kBq/m3. The gas permeability of the weathered granite soil is dominantly high and medium, and that of most Quaternary sediments is low. Based on these data, the radon risk of soils in the study area is accurately classified, and the result shows that the classification method of radon risk of soil based on the radon concentration and gas permeability is proved to be feasible.

Key words: soil radon, gas permeability of soil, radon mapping, RAD7, RADON JOK
