If a source of radon isotopes is adsorbed on the surface of an artificially prepared crystal, the radioactive gas emanation does not depend on the size of the crystal, although emanation is proportional to the specific surface on cocrystallization of radium with an isomorphous salt. The radioactive gas emanation of minerals depends only slightly on a change in specific surface. An increase of radioactive gas emanation as a function of mesh size depends on preservation of the mineral sample and maintenance of the conditions of distribution of radium in the sample. As a rule, the evolution of thoron from uranium minerals differs from that of radon and actinon, while in thorium minerals, the evolution of actinon, and sometimes that of radon, differs from that of thoron. An explanation of this behavior is very essential in age determinations from the lead isotope content. The anomalous behavior of actinon may have disrupted the ratios of AcX and Ra in the minerals.
