Abstract

The feasibility of detecting gamma rays with energies below 1.5 MeV by means of a large-volume liquid-filled Cerenkov counter has been examined, together with the characteristics and limitations of an experimental counter. Various liquids (water, glycerol, sodium iodide solution; and glycerol plus a wavelength shifter) were investigated as possible Cerenkov media. A rectangular counter containing 1.2 liters of the latter medium could detect 10 nCi of 58Co or 59Fe at 10 cm in a counting time of 1000 s.

摘要

研究了利用大体积充液切伦科夫计数器探测能量低于1.5兆电子伏的伽马射线的可行性，以及一个实验计数器的特性和局限性。研究了各种液体（水、甘油、碘化钠溶液；以及加了波长移位剂的甘油）作为可能的切伦科夫介质。一个装有1.2升后一种介质的矩形计数器在1000秒的计数时间内，在10厘米处能够探测到10纳居里的58钴或59铁。
