本文介绍了一种灵敏耐用裂变计数器的设计和性能。该计数器通过U235裂变探测热中子。计数器的灵敏度为0.7计数/中子·cm−2，背景计数率为5计数/秒。有用的范围是10至2×105个中子/cm 2·秒，并且计数器将在存在1010个伽马射线/cm 2·秒的情况下在此范围内运行。
The design and performance of a sensitive rugged fission counter is described. The counter detects thermal neutrons by means of U235 fission. The sensitivity of the counter is 0.7 count/neutron·cm−2 for a background counting rate of 5 counts/sec. The useful range is 10 to 2×105 neutrons/cm2·sec, and the counter will operate over this range in the presence of 1010 gamma rays/cm2·sec.
