Possible extended utilization of a 68Ge/68Ga source as a surrogate 18F reference source was studied. Some effects and uncertainties might arise from the difference of constructions between chambers that were used in the source calibration and those p

Empirical calibrations of full-energy peak and total efficiency curves for well-type and coaxial p-type germanium detectors were carried out using several combinations of practical nuclides. As a result, reliable efficiency functions of both types of

Radioactive impurities might cause significant error in the activity determination of a target nuclide using ionization chambers. In the present study, an impurity correction technique for (201)Tl sources was performed by applying two different respo

In the use of photon detectors having sensitivity to β-rays or internal conversion electrons (CEs), β-γ and/or X-CE coincidence summing may arise. In particular, an n-type germanium detector has a thin dead layer and window, causing considerably h
