Present and future radiation dosimetry for Russian cosmonauts.

This report describes the features of the cosmic-radiation monitoring system defined by the parameters of cosmic radiation and by the conditions of operation of dosimeters in space. The objectives of the operative and personal monitoring on board Russian spacecraft have been defined and substantiated. Accordingly, the operating characteristics of the dosimeters used during the flights of Russian manned spacecraft are given. The feasibility of perfecting the radiation monitoring facilities to be used in future manned space missions is discussed. The methods used by the Radiation Safety Service during manned space missions are described.
