为减少被动积累法测定土壤中氡浓度的测量时间，探讨了一种快速测量土壤氡浓度的方法。该方法将未平衡时的测量结果通过最小二乘法拟合得到相关参数值，进而得到平衡时的土壤氡浓度。方法研究中，研制了一台土壤氡浓度快速测量仪。实验室和现场测量结果表明，拟合值和平衡时的氡浓度值之间的相对偏差在7％以下，测量时间缩短3h以上。

To reduce the time for measuring radon concentration in soil by passive accumulation method, a rapid method has been studied.The method can provide related parameter values that fitted from unbalanced result by least square method and then get the balanced radon concentration.On account of above conditions, a rapid measuring instrument for radon concentration in soil has been researched.Measured results show that the rela-tive deviation between the fitting values and the balanced values is below 7%,measuring time is shorten more than 3 hours than before.
