Effective equipments for measuring cosmic radiation dose

Systems for measuring cosmic radiation necessary for assessment of spacemen's health management and of biological space experiment results are now insufficient. The biological and medical purposes of measuring cosmic radiation are monitoring of the circumstantial radiation for examination of spacecraft transport code, personnel monitoring for radiation protection and biology experiments for assessing the radiation effects. Equipments possibly suitable for the measurement are semiconductor, scintillation and Cherenkov detectors for the transport code, photo-luminescence dosemeters, solid track detectors (for high LET components) and semiconductor detectors (for works outside the spacecraft) for the personnel monitoring and photo-luminescence dosemeters, solid track detectors responsible for 4π direction and equipments with a remote-controlled detectors for experiments. Development of those practical equipments is awaited.(K.H.)
