title: Study of long term radon transport by measuring the difference of the 210Pb and 226Ra activity in soil as a function of the depth.
abstract: Long term radon transport has been studied by measuring the activity difference of 210Pb and 226Ra in soil as a function of the depth. The results are from test pits of 1-2 m depth made at a dam of a tailings pond and at the plateau of a waste rock pile. Soil samples of about 1 kg were taken at a successive distances of 5 cm and analyzed by means of gamma-ray spectroscopy using low background germanium n-type detectors. It is shown that by this method nearly model independent information about the radon transport over a period of several decades can be inferred from the data.
