摘要：
A method for determination of aluminum and phosphorus in biological materials, based on activation in a nuclear reactor and measurement of Al-28, produced by the Al-27(n, gamma)Al-28 and P-31(n, alpha)Al-28 reactions, is described. Irradiations in the undisturbed and epicadmium spectra provide a two-equation system in order to determine the contributions of aluminum and phosphorus to the total activities. Germanium is used as an integral flux monitor,and comparator, through the reactions: Ge-74(n,gamma)Ge-75, Ge-76 (n,gamma)Ge-77, and Ge-72 (n,p)Ga-72.
