[The methodology of establishing the radiation hazard to cosmonauts on long-term mission based on the generalized dosimetric functional].
The paper describes an original methodology for evaluation of the radiation hazard to cosmonauts on mission based on generalized dose from ionizing radiations. This is a new dosimetric functional that allows convert the complex radiation of space to standard radiation. The conversion is achieved by calculation of mean tissue equivalent doses from each source of radiation hazard in space flight and scaling factors which take into account the radiobiological effect of intricate macrospatial and temporal dose distributions along the human body. Besides, consideration is given for the impact of non-radiation factors inherent to space flight. The generalized dose which is the dose from standard radiation inducing radiation damage similar to the multicomponent space radiation can be used to ascertain the character and degree of performance degradation, and radiation risk for cosmonauts both in and long after mission.
