摘　　要：双源法测量土壤潜势氡浓度是利用土壤表面氡析出率和浅层土壤氡浓度,确定土壤潜势氡浓度的方法。为了实现双源法快速测量土壤潜势氡浓度,项目对Mathematica、Excel及C语言程序3种计算土壤潜势氡浓度的方法进行研究。通过计算,验证了3种方法计算结果一致,其中Mathematica和Excel需依靠PC机进行,不便实时给出测量结果;而C语言程序易于移植,便于土壤潜势氡浓度测量仪的开发,为土壤潜势氡浓度的测量提供了技术支持。Dual-source method uses the way which takes advantage of soil surface radon exhilaration rate and shallow soil radon concentration to determine the potential soil radon concentration .In order to achieve the rap-id measurement by using the dual -source method to measure the soil radon concentration ,we made some re-search on three ways that are Mathematic ,Exce and C language program to calculate the potential radon concen -tration.These comparative experiments show that three methods can have the same result .Because Mathemtica and Excellrelied on the PC ,there is inconvenience on achieving the real -time measurement results;The C lan-guage program is easy to transplant ,easy to develop the measurement instrument of potential soil radon concen -tration which can provide technical support for the potential soil radon concentration measurement .
