Abstract: In this work, it is presented an experimental assembly based on electric capture of radionuclides in order to discriminate the alpha activity of Po-214 (radon decay product) from Po-212 (thoron decay product) one. The alpha activity was registered with CR-39 analyzing etch pit diameters and optical density. This discrimination may allow for the estimation of the relative contribution of the alpha activity due to thoron decay products compared to the total activity due to radon decay products.
