  • Title: [Total radiation risk from interplanetary and orbital missions to cosmonauts by the end of career and over the life time].
    Author: Shafirkin AV, Venediktova VP.
    Journal: Aviakosm Ekolog Med; 1999; 33(5):57-64. PubMed ID: 10590812.
    Abstract:
    Models of radiation rate of mammalian mortality and algorithm for calculating the generalized dose from space radiations laid the basis for mathematical description of the probability of cosmohaut's survival in a delayed period after exposure as a function of generalized dose. Derived relations are intended to estimate the total radiation risk by any time point following exposure; expressions can be used to predict reduction inf mean expected lifetime after exposure of cosmonauts to different radiation doses. Presented are calculations of total radiation risk to cosmonauts from interplanetary and orbital missions of varying length by the end of career and over the whole lifetime. Additionally, calculated reduction in mean expected lifetime in consequence of space radiation exposure is given and the dependence of delayed radiation effects on mission length, spacecraft shielding, solar cycle, and age at the launch is analyzed.
