The activity of 15O and 13N per unit volume of air produced by a 25 and a 45-MeV medical accelerator was determined by direct measurement. The accelerators were operated in such a fashion as to produce maximum activation of the treatment room air. Levels of the order of 1% or less of the maximum permissible concentration in air for 15O and 13N were found immediately after accelerator shutdown. Three different techniques for calibrations of the air detector were investigated.
通过直接测量确定了一台25 MeV和一台45 MeV医用加速器每单位体积空气中产生的(^{15}O)和(^{13}N)的活度。加速器以能使治疗室空气产生最大活化的方式运行。加速器停机后立即发现，(^{15}O)和(^{13}N)的水平为空气中最大允许浓度的1%或更低。研究了三种不同的空气探测器校准技术。
