内容記述 | The imaging plate is employed as a radiation sensor for obtaining two-dimensional radiation images of natural radioactivity. We used it to evaluate the autoradiography of several types of Archean and Proterozoic granitoids and ultramafic rocks from South Africa for obtaining the distribution of radiation emitters. The semiquantitative dose of natural radioactivity, represented by PSL value in the imaging plate measuring system (the intensity of photostimulated luminescence per unit area), is shown in terms of the potassium content. Both beta and gamma ray doses were estimated on the basis of functional relationship between potassium content and respective PSL values. Comparing Japanese granitoids analyzed in this study, Archean and Proterozoic granitoids from South Africa used here show relatively high radiation effects caused by disintegration of uranium, thorium and actinium decay series. | |||||
