摘要
Field measurement of soil radon concentrations was carried out and the corresponding soil samples were collected in Zhuhai area for analyzing uranium content.The linear simulation was used to analyze the measured data.The result shows that soil radon concentrations are positively correlated with the uranium content of the soil.The probability of soil radon concentrations greater than 20 000 Bq/m3 has a good linear relationship with uranium content of soil.The level of the soil radon concentrations is influenced by a number of factors and the measured values are not stable,and hence the study of the probability of the excess is more scientific.According to the relational model and risk classification,we can quickly evaluate regional soil radon hazards.
