摘要： 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.
摘要翻译：用于氡气和氡子产品的紧凑型低成本轨迹配准检测器包括具有可拆卸闭合盖的壳体，用于保持具有沿着由α粒子穿过的路径形成损伤轨道的特性的轨道配准材料条。带材通过一体形成的直立的肋条被保持在壳体内，该直立肋条紧邻壳体的直径相对的内侧壁部分，形成基座支撑件的第一组肋条和提供横向支撑件的第二组较长的肋条。不渗透颗粒和氡子产品的微孔过滤器仅将氡气仅允许到壳体的内部。有孔闭合盖具有中心固体部分，为带的上表面提供辐射屏蔽，使得能够在检测器从曝光位置取回之后容易地区分下曝光表面。外壳由不含任何残留的α粒子辐射的纯聚乙烯材料制成。围绕外壳的外部缠绕的柔性条带提供悬挂带和用于输入曝光信息的信息表。

摘要： A personnel neutron dosimeter consisting of a single recorder and a (n, .alpha.) radiator wherein exposure to two levels of neutron energy produces differing plural forms of damage sites in the recorder, which damage sites, upon development, will differ sufficiently in character or as to location on the recorder to permit separate identification and measurement of the neutron dose received from two portions of the neutron spectrum.
