The accelerator operated routinely at 400 GeV during CY-1981 with about the same number of protons accelerated during CY-1981 as in CY-1980. The total number of protons accelerated in 1981 was 1.4 x 10/sup 19/. Typical operation was at about 45 percent of the design intensity of 5 x 10/sup 13/ protons per acceleration cycle. During CY-1981 there were no abnormal occurrences which had an impact on the facility and its operation. Copper sulfate was used this year to control algae and weed growth in ditches and is suspected of causing the death of three birds. The maximum potential radiation exposure at the site boundary during CY-1981 (fence line assuming 24 hr/day occupancy) was 1.8 mrem compared to 0.3 mrem last year. The total potential radiation exposure to the general off-site population from Fermilab operations during CY-1981 was 11 person-rem compared to 1 person-rem last year. The increase in potential exposure occurred as a result of the off-site neutron dose this year. All exposure was from external radiation. Airborne radioactivity was released across the site boundary in small amounts throughout the year from the stack ventilating a Neutrino Area enclosure where the proton beam strikes a target. The radioactive gas was primarily /sup 11/C, total quantity released was 1.45 kCi, and the maximum dose at the site boundary was 0.3 mrem for 1981. The average concentration at site boundary based on measurements at the stack was 0.06 percent of the Concentration Guide.There was also a controlled release of tritium in tritiated water evaporated as a means of disposal for the first time at Fermilab in CY-1981. The total quantity released to the atmosphere was 420 mCi.
