Environmental monitoring report for calendar year 1980
The accelerator operated routinely at 400 GeV during CY-1980 with about half the number of protons accelerated during CY-1980 as in CY-1979. The total number of protons accelerated in 1980 was 1.2 x 10/sup 19/. The lower total was the result of an extended shutdown from the end of June until the middle of November for construction and because of a shortage of operating funds. During CY-1980 there were no abnormal occurrences which had an impact on the facility and its operation. The maximum potential radiation exposure at the site boundary during CY-1980 was 0.3 mrem compared to 2 mrem last year. The total potential radiation exposure to the general off-site population from Fermilab operations during CY-1980 was 1 person-rem compared to 3 person-rem last year. Airborne radioactivity was released across the site boundary in small amounts throughout the year from the stacks ventilating a Neutrino Area enclosure where the proton beam strikes a target. The radioactive gas was primarily /sup 11/C, total quantity released was 1.3 kCi, and the maximum dose at the site boundary was 0.3 mrem for 1980. There was also a controlled release of tritium produced in helium gas near a target in the Meson Area. The total amount of tritium released was 240 mCi. The average tritium concentration at the site boundary was about 0.00001 percent of the Concentration Guide (Sections 3.2 and 4), resulting in a negligible off-site exposure. The off-site release of tritium in surface water totaled 240 mCi, five times last year's release, primarily because water flowed off the site for 7.5 months compared to less than two months in 1979.
