We introduce the status of the 300-MeV electron linear accelerator used for radioanalytical studies at Tohoku University. In the accelerator facility, several scientific programs for producing radioactivities and use have been performed in several fields, such as photon activation analysis, study of nuclear phenomena influenced by chemical nature, radioisotope production for trace elements, radiation chemistry and irradiation effects by electrons and photons, radioisotope labeling and its mechanism. We show the outlook of the facility, instrumental developments of a beam-course, an irradiation system and several measurement devices. Further, we display a radioanalytical topic in practice, evaluation of trace amount of potassium in high-purity reagent of Gd2O3 by photon activation analysis.
