摘要： Albedo dosimeter encapsulation for measuring neutron and gamma radiation in at least two dosimeter zones, comprises a casing having cadmium or boron containing walls which have neutron absorbing capability. The casing has a front side which faces a radiation field and a rear side which faces a body which carries the encapsulation. The rear side of the casing is closed by a cadmium or boron containing rear wall having a first portion and a second portion. A cover is located at the front side of the casing and has a cadmium or boron containing wall portion and a window portion. The casing has a first zone for holding a first dosimeter means and a second zone for holding a second dosimeter means. The first zone is aligned with the cadmium or boron containing wall portion of the cover and the first portion of the rear wall. The second zone is aligned with the window portion of the cover and the second portion of the rear wall. The cadmium or boron containing wall portion of the cover has a neutron absorbing capability which is different from the neutron absorbing capability of the first portion of the rear wall. The first portion of the rear wall has a neutron absorbing capability which is different from the neutron absorbing capability of the second portion of the rear wall.
摘要翻译：用于在至少两个剂量计区域中测量中子和γ射线的反照率剂量计封装包括具有中子吸收能力的具有镉或硼的壁的外壳。壳体具有面向辐射场的前侧和面向承载封装体的背面。壳体的后侧由具有第一部分和第二部分的含镉或硼的后壁封闭。盖位于壳体的前侧，并且具有含镉或硼的壁部分和窗口部分。壳体具有用于保持第一剂量计装置的第一区域和用于保持第二剂量计装置的第二区域。第一区域与盖的镉或硼的壁部分和后壁的第一部分对准。第二区域与盖子的窗口部分和后壁的第二部分对准。盖的含镉或硼的壁部分具有与后壁第一部分的中子吸收能力不同的中子吸收能力。后壁的第一部分具有不同于后壁的第二部分的中子吸收能力的中子吸收能力。
