Assessment of secondary radiation from the earth surface by availability of uranium - 238

Abstract

The indispensability of rare earth elements for global markets cannot be overestimated. The use of rare earth metals is found in any high-tech industry. Most deposits of rare earth metals are open. The remaining part is a placer or is located in places inaccessible for development. The development of remote methods for the exploration of deposits of rare earth metals in hard-to-reach places and their placers will reduce the financial costs of the economy, increase the country's raw material potential and help reduce carbon emissions. The article attempts to analyze the possibility of detecting the desired rare earth elements based on the remote method for secondary radiation generated by the alpha decay of uranium-238 and thorium-232. The results of the research will provide an opportunity to map local changes in the radiation background of the earth's surface based on the measurement of weak electromagnetic radiation in the frequency range of 1.4 - 1.7 GHz.
