Advanced active dosimetry instrumentation to measure absorbed dose, charged particle spectra, and linear energy transfer spectra inside a manned spacecraft has been designed and tested. This system employs a tissue equivalent Bragg-Gray ionization chamber and silicon solid state detectors in a single small lightweight, rugged, and man-space qualified unit. The instrument measures dose rates from 0.2 milliradhour to 25 radhour, linear energy transfer spectra from 3.5 to 42.4 Kevmicron, and proton and alpha particle energy spectra from 0.5 to 75 Mev. The active dosimeter is equipped with a portable radiation sensor for use in astronaut on-body and spacecraft shield surveys during passage through significant space radiation fields. This report presents the culmination of the first phase of the development of the advanced active dosimeter. It is scheduled for flight test as part of Department of Defense Radiation Effects Experiment D008 on the first Apollo Applications Flight. Author
