As manned space missions are becoming routine operations, the complex arsenal of instruments for personal radiation monitoring ought to be simplified. The necessary compromises concerning accuracy and completeness of record should be carefully evaluated. The report analyzes the dosimetrically relevant parameters of the three main contributions to the astronauts radiation exposure in space trapped protons, tissue disintegration stars, and neutrons. It is shown that interference and superposition effects from different components impose certain principal limitations on resolution. Possible ways and means for a system of restricted dosimetry which would record only certain parameters and establish the total dose equivalent from known characteristics of the radiation field are discussed.
