Abstract

To date, the methods of taking into account emanation in the radiometric analysis and sampling of uranium ores have been developed in sufficient detail. For thorium and uranium-thorium ores these questions are poorly studied, because it is believed that thoron has a short half-life (TTp = 54.5 sec), so it quickly comes into equilibrium with the parent substance ...
