Characteristic of thoron (220Rn) in environment.


This paper describes importance of 220Rn (hereafter thoron) progeny measurement for the dose estimation. Although the spatial distribution of thoron activity concentration strongly depends on the distance from wall surface as an indoor thoron source), a homogeneous distribution was expected to be observed for 212Pb activity concentration which was one of… (More)
