The indoor radon concentration was estimated based on the radon flux in soil and groundwater. The indoor radon concentration in Budhakedar area of Garhwal Himalaya, India is estimated to be 3.0-131.4 Bq/m(3) in summer and 4.6-92.4 Bq/m(3) in winter. Based on the available data from study area, the calculated value of diffusion coefficient for the soil ranges from 0.1×10(-2) to 3.0×10(-2)cm(2) s(-1) in the summer season and 0.1×10(-2) to 0.4×10(-2)cm(2) s(-1) in the winter season. The calculated value of diffusion flux in the study area is found to vary from 0.1×10(-2) to 16.1×10(-2)Bq m(-2) s(-1) in summer season and 0.1×10(-2)-12.2×10(-2)Bq m(-2) s(-1) in winter season. The formulation was tested by comparing the results of radon values from two different seasons of a year.
室内氡浓度是根据土壤和地下水中的氡通量估算得出的。印度加瓦尔喜马拉雅地区布德哈凯达尔地区的室内氡浓度，夏季估计为3.0 - 131.4贝克勒尔/立方米，冬季为4.6 - 92.4贝克勒尔/立方米。根据研究区域的现有数据，土壤扩散系数的计算值在夏季为0.1×10⁻²至3.0×10⁻²平方厘米²/秒，冬季为0.1×10⁻²至0.4×10⁻²平方厘米²/秒。研究区域内扩散通量的计算值在夏季为0.1×10⁻²至16.1×10⁻²贝克勒尔·米⁻²·秒⁻¹，冬季为0.1×10⁻²至12.2×10⁻²贝克勒尔·米⁻²·秒⁻¹。通过比较一年中两个不同季节的氡值结果对该公式进行了检验。
