Implementation of radiation protection requirements in the limitation of the release of radioactive effluents

The paper describes procedures of implementation of the radiation protection requirements referring to the control of radioactive effluents. Derived limits are introduced on the basis of environmental models of the concentration factor type. Optimization of control is discussed for the case where decision between several levels of protection is required, an example being presented. A procedure for restricting future exposures by limiting the dose commitment per unit practice is discussed. An appendix summarizes assessments of collective dose commitments from environmental releases in the nuclear fuel cycle. (author)
