The authors compare two different methods to determine the activity of the air induced by the bremsstrahlung of medical accelerators. The activities of the air resulting from maximum photon energies of 16 to 42 MeV are measured with a proportional counter tube ("direct measurement") and by means of activation analyses of imidazole, triazole, malonic acid, and urea specimens ("indirect measurement"). The results are compared.
作者比较了两种不同的方法来测定医用加速器轫致辐射所产生的空气的活性。使用正比计数管（“直接测量”）以及通过对咪唑、三唑、丙二酸和尿素样本进行活化分析（“间接测量”）来测量最大光子能量为16至42 MeV时所产生的空气的活性。对结果进行了比较。
