电离室是历史悠久的射线探测器之一,早期是不密封或半密封的空气电离室,主要用于伦琴标准及剂量测量。后来出现了全密封,工作介质是高压或常压惰性气体(或其他特殊气体)的充气电离室。 四十年代以来,随着反应堆的发展,堆用硼电离室可算第一批真正全密封的充气电离室,至今仍是反应堆的主要探测元件之一。 Ionization chamber is one of the long-established radiation detectors, the early is not sealed or semi-sealed air ionization chamber, mainly for Lun Qin standards and dose measurement. Later appeared sealed, the working medium is high pressure or atmospheric inert gas (or other special gas) inflatable ionization chamber. Since the 1940s, with the development of the reactor, the first batch of truly sealed gas-filled ionization chambers can be considered as one of the main detection elements of the reactor.
