Abstract

After radon gas diffuses into a diffusion chamber, 218Po will be formed. Due to its short half-life, a fraction f of 218Po decays before deposition onto available inner surfaces of the chamber, and the deposition fraction (1-f) represents the part which decays after deposition. In the present work, f has been experimentally determined for six diffusion chambers with different materials and dimensions using the radial distribution of track density on the LR115 detectors inside the diffusion chambers. For all the six studied diffusion chambers, f was found to be ∼0.4. Therefore, the deposition fraction does not depend on the shape and dimensions of the diffusion chambers, the surface to volume ratios or the internal surface materials of the diffusion chambers. © 2003 Elsevier Science Ltd.
