Characteristics of a Radon Diffusion Chamber With Electrical Collection Using Plastic Nuclear Track Detectors.
NTIS: PB/84-184209 Available for Reference At Bureau of Mines Libraries :17 pages
A portable radon diffusion chamber was tested with electrical collection of radon daughter nuclei for enhancement of sensitivity. The detector was small enough to be worn suspended from a belt. With a battery-supplied high voltage, the sensitivity was found to be 1.43 Tracks/cm2 per pci-h/l of ambient radon at 50% relative humidity. The track densities on the surfaces of the cr-39 plastic nuclear track detectors were found to be nonuniform, making the determinations of average densities with high accuracy difficult. The fabrication of electrets for use in the detector was investigated in accordance with published techniques with negative results.
