The photoelectron rates were estimated for commercial photon sources of Am-241, Sn-119m, Te-125m and Cd-109 with activities of 0.55-3.7 GBq. Photoelectrons ejected by Am-241 gamma- and X-rays from Co convertors were measured with two different electron spectrometers and obtained energy spectra were compared with Monte Carlo predictions.
