✦ Synopsis

In the Fast and Muhi--functionsl Radon Meumemeat Method, the " Po + positive ions are collected by the mtic electric field produced by electret. The reaponβ€’e factor obtained with this method is as high as 4.70 tracks β€’ cm'SBq -s rash -s and so the sensitivity of radon measurement is improved largely. The lower detecting limits for radon concentration measurement (for 10h sampling)and radon flux rate measurement (for lh sampling) are 0. 13 Bqm 4 and 0. 14mBqm% "1 ,respectively. The method has been widely applied.

A method for measuring thoron and radon gas concentrations has been developed. A sample of the radioactive gas is passed through a filter, to remove its short-lived decay products, and into a small chamber having a diffused-junction (SiDJ) detector, or a silicon-barrier (SiB) detector for gross a-pa
