|Title:||A Possibility Of Monitoring Indoor Radon Daughters By Using Cr-39 As An Alpha-spectrometer|
|Abstract:||Alpha-spectroscopy using CR-39 has been employed by us in monitoring radon and its daughters. By means of measuring the track diameters (considering only the tracks whose ratio between the major and the minor diameters is ≤ 1.100), one can find the energy distribution of the incident α-particles and, in this way, obtaine information about the plate-out rate of radon daughters on material surfaces and also about the concentration of radon and daughters present in the air. In this work, it is shown how radon and daughters monitoring can be improved by using this technique. © 1995.|
