Determination of tissue calcium by nondestructive neutron activation analysis.
A method is described for measuring the concentration of calcium in arterial tissue by neutron activation analysis. The principal advantage is that the method is nondestructive and is ideal for analytical situations in which multiple biochemical measurements are required on a few-milligram sample. Application of the method is illustrated here by a study of aortic calcium metabolism in pigeons a...

15 صفحه اولDetermination of chromium in biological materials by radiochemical neutron activation analysis (RNAA) using manganese dioxide
A procedure based on radiochemical neutron activation analysis was developed for the determination of chromium in biological materials. The procedure consists of irradiation of reference and test samples in a nuclear reactor, microwave sample digestion, selective and quantitative radiochemical separations of chromium and gamma-ray spectrometric measurement of 51Cr. Separation of chromium from t...
