Measurements and modeling of gamma absorbed doses due to releases from a linear proton accelerator: experimental design and preliminary results
External radiation levels due to positron annihilation radiation from /sup 11/C, /sup 13/N, and /sup 15/O released by the 800 MeV linear proton accelerator at the Los Alamos Meson Physics Facility (LAMPF) have been monitored at a fence-line location both by thermoluminescent dosimeters (TLDs) and high pressure ionization chambers (HPICs). The accelerator is located in irregular terrain consisting of mesas and canyons. Fifteen-minute, accumulated external radiation levels were recorded with the HPICs. Instruments on a nerby meteorological tower concurrently measured wind speed and direction at three levels, temperature at two levels, solar radiation, and rainfall. Real-time radionuclide release rates and stack velocities were measured at the release point with in-stack monitors. This paper presents analyses of short-term radiation levels using HPICs and long-term levels using TLDs. Work being done to develop a computer model to predict external radiation levels based on meteorological data is also discussed.
