据观察，源自大气氡子体的伽马射线对环境辐射的贡献约为 10% 至 25%。在测量环境伽马射线强度和大气氡子体浓度的日变化时，我们发现它们之间存在循环相关性。通过模型计算，证实这一现象的原因是海拔高度氡子体浓度的日变化。
The contribution of gamma-rays originating from the atmospheric radon daughters to the environmental radiation is observed to be from ∼ 10 to 25%. In the measurement of diurnal variation of the environmental gamma-ray intensity and the atmospheric radon daughters concentration, we have found a looping correlation between them. By using a model calculation, the cause of this phenomenon is confirmed to be the diurnal variation of the altitudinal radon daughters concentration.
