Radiological exposure to naturally occurring radionuclides can give rise to non-trivial radiation doses, but most of this exposure cannot be avoided. Only in the case of excessive radon concentrations in housing have some corrective measures been taken locally. A description of the main treatment and disposal routes for very low radioactive material is provided and a summary of currently accepted criteria and rules for exemption from the system of notification, registration and licensing, at both national and international levels, is given. The essential features of an evolving international consensus on exemption principles are also presented. Scenarios resulting in the highest exposure have been selected and calculations have been performed, with the aim of finding acceptable concentrations for specific radionuclides and groups of radionuclides. A short review of available hardware and software for measuring and controlling very low levels of radioactivity is also given.
