Description/Abstract:
OAK RIDGE TENNESSEE...ONE OF THE MEASUREMENTS BEING CARRIED OUT IN THE NASA SUPPORTED APOLLO SHIELDING PROGRAM AT OAK RIDGE NATIONAL LAB IS THE DETERMINATION OF THE TOTAL PHYSICAL DOSE AT A SPECIFIC POINT IN SI MULATED TISSUE THAT RESULTS FROM THE INTERACTIONOF HIGH ENERGY PROTONS WITH MATERIALS OF THE SPACE CAPSULE OR WITH THE TISSUE ITSELF. THE P HOTOGRAPH SHOWS THE APPARATUS DESIGNED FOR SUCH MEASUREMENTS IN CONNEC TION WITH EXPERIMENTS USING HIGH ENERGY PROTON ACCELERATORS. WITHIN T HE 42 CM DIAMETER WATER FILLED SPHERE CALLED A "PHANTOM" BECAUSE IT SI MULATES A SPHERE OF HUMAN TISSUE) CAN BE SEEN A SMALL ----- ARGON OR E THYLENE FILLED IONIZATION CHAMBER. THIS CHAMBER CAN BE TRAVESED FROM THE FRONT TO THE BACK OF THE SPHERE WHICH IN TURN CAN BE ROTATED IN LA TITUDE AND LONGITUDE THUS PERMITTING A COMPLETE MAPPING OF THE VOLUME. THE ENERGY DEPOSITED AT ANY POINT WITHIN THE PHANTOM CAN BE RELATED TO THE IONIZATION PRODUCED IN THE CHAMBER AT THE OINT OF INTEREST. IT SHOULD BE EMPHASIZED THAT THIS APPARATUS MEASURES ONLY PHYSICAL DOSE AND NOT BIOLOGICAL DOSE. EVALUATION OF THE LATTER QUANTITY WOULD REQU IRE MUCH GREATER DETAIL IN THE NATURE OF THE RADIATION AND CONSIDERABL E BIOOGICAL INTERPRETATION.
