Phantom—dosimeter for estimating effective dose onboard International Space Station

The dose values in body's critical organs are necessary for estimating the effective dose. The tissue-equivalent phantom is used for such assessment as a rule. The spherical phantom is best fit for this goal. Therefore, the method developed on the basis of such phantom application becomes a good mean of effective dose estimating onboard the International Space Station. The main problems connected with developing a method of assessing an effective dose in the human's body organs with usage of a spherical phantom are presented in the paper. Proposed method can be used for monitoring the daily effective dose of crewmembers exposure for undisturbed radiation conditions of the flight.
