ABSTRACT:
A compact low cost track registration detector for radon gas and radon daughter products includes a housing with a removable closure cap for retaining a strip of track registration material having the property of forming damage tracks along paths traversed by alpha particles. The strip is retained within the housing by integrally formed upstanding ribs located closely adjacent diametrically opposite inner side wall portions of the housing, a first set of ribs forming a pedestal support and second set of longer ribs providing transverse support. A microporous filter impervious to particles and radon daughter products admits only radon gas to the interior of the housing. The apertured closure cap has a central solid portion providing a radiation shield for the upper surface of the strip to enable the lower exposure surface to be readily distinguished after the detector has been retrieved from an exposure site. The housing is fabricated from a pure polyethylene material free from any residual alpha particle radiation. A flexible strip wrapped about the exterior of the housing affords both a hanging strap and an information sheet for user entry of exposure information.
