Using a 252 Cf neutron source we have calibrated the response of Ge detectors to fast neutrons and deduced the expression for determination of the flux of fast environmental neutrons based on the intensity of the spectral structure at 691.3 keV. We a

We suggest that radioactive food contamination, as determined solely by a quantitative gamma-ray spectroscopic measurement, may, apart from the total activity per unit mass, be for quick reference conveniently characterized by another single figure w

An x-ray fluorescence (x.r.f.) method is described for the determination of platinum contents (0.3–0.6%) in some special types of platinum catalysts. Calibration graphs were linear in the range 30–700 μg g−1 platinum with a 3σ detection limit
