ABSTRACT:
A method for the qualitative or quantitative analysis of isotopes, characterized by bombarding a substance with X rays or electrons of a previously determined dose and energy for analyzing an isotope in the substance to be detected or measured, to produce an excited state of atomic nuclei of the isotope and thereafter detecting the existence or measuring the dose of the gamma rays or internal conversion electrons emitted in the course of the deexcitation process of the atomic nuclei in the excited state to the ground state. According to the present invention, a particular isotope or element in a substance can qualitatively or quantitatively by analyzed in a simple and precise manner within an extremely short period of time without the necessity of using a large scale apparatus.
