摘要：
The recording efficiency of gamma radiation is examined for direct measurement of the concentrations of radionuclides deposited on cylindrical aerosol filters or the walls of air ducts or pipes that are coaxial with cylindrical crystals. Analytic solutions are obtained and recording efficiencies are calculated for a hollow cylindrical source with a diam of 50 cm and a length of 50 cm and standard scintillation crystals.
