Instrumental Photon Activation Analysis with Short-Time Irradiation for Geochemical Research

This paper introduces instrumental photon activation analysis (IPAA) utilizing short-lived products of photonuclear reactions, mainly (γ, n) and p), initiated by bremsstrahlung from the MT-25 microtron. A rapid nondestructive IPAA method for geochemical major element is introduced as a tool basic characterization rocks. Procedures were developed parameters such beam energy irradiation-decay-counting times optimized with representative set reference materials, an scheme was applied in various geological samples. complete analytical combined long-time irradiation possibility utilization photoexcitation reactions γ′) are briefly outlined.
