的扩散系数的测量表明，它是一个函数的长度：所使用的扩散管的流量比（或年龄），并导致的结论是，有没有单一的扩散系数的RaA和假设，扩散系数取决于化学性质的反应产物之间形成的RaA和气体环境。RaA在各种气体气氛中的静电收集效率与气体的电离势相关。有必要进一步调查氡子体的化学性质，以了解其剂量测定和在人肺中的沉积。
Measurement of the diffusion coefficient of RaA showed that it was a function of the length: flowrate ratio of the diffusion tube used (or of age) and led to the conclusion that there was no single diffusion coefficient for RaA and to the hypothesis that diffusivity depended on chemical nature of the reaction product formed between RaA and the gaseous environment. Electrostatic collection efficiency of RaA in atmospheres of various gases correlated with ionization potential of the gases. There was a need to investigate further the chemistry of radon daughters to understand their dosimetry and deposition in the human lung.
