Simplification of analysis for comparison of radioactive characteristics and its application to some minerals for radon therapy

Research output: Contribution to journalArticle

Abstract

To simplify the analysis of the radioactive characteristics of the minerals for the radon therapy, we developed a simple method to calculate the ratio of the uranium series to the thorium series (U/Th) without using activity. The ratios calculated by this method agreed well with the ratios calculated using the activity. We applied this method to some minerals for the radon therapy. As a result, the U/Th's for the sludge of Misasa, the hokutolite, the mineral of Badgastein, and the two kinds of commercially available minerals were 22, 50, 0.94, 0.26, and 0.20, respectively.
