    • A radiation detection assembly includes an ionization chamber for detecting radiation. The ionization chamber includes a volume of pressurized gas. An exterior enclosure houses the ionization chamber within an interior volume. The exterior enclosure includes a frangible section. A relief assembly defines a gas flow path from the ionization chamber to the frangible section of the exterior enclosure. The frangible section releases pressure from within the ionization chamber when the pressurized gas within the ionization chamber exceeds a predetermined pressure such that at least some of the pressurized gas flows through the relief assembly and through the frangible section of the exterior enclosure. The pressurized gas is then released to an exterior of the exterior enclosure. A method of reducing pressure within a radiation detection assembly is also provided.
    • 放射线检测组件包括用于检测放射线的电离室。 电离室包括一定体积的加压气体。 外壳将电离室容纳在内部容积内。 外壳包括易碎部分。 减压组件限定从电离室到外壳的易碎部分的气体流动路径。 当电离室内的加压气体超过预定压力时,易碎部分从电离室内释放压力,使得至少一些加压气体流过减压组件并穿过外壳的易碎部分。 然后将加压气体释放到外壳的外部。 还提供了一种减少放射线检测组件内的压力的方法。
