Site environmental report for calendar year 1987
Fermilab conducted a full year of high-energy physics research in CY-1987. The colliding beam physics program began in early January and extended into May. During the colliding beams run a total of 54 curies (Ci) of /sup 11/C, /sup 13/N, and /sup 41/Ar were released from the Antiproton Source stack. During the fixed target program a total of 27 curies of radioactive gas, primarily /sup 11/C, were released from the Neutrino Area stack. There was a negligible exposure from penetrating radiation during the colliding beams experiments; however, muons from the new Muon Laboratory gave a maximum site boundary potential exposure equal to the highest previous annual potential exposure which occurred in 1976. This result gave a total potential radiation exposure of 13 millirem (mrem) at the site boundary during CY-1987 compared to an average of 3.3 mrem per year for the previous years. The total potential radiation exposure to the general off-site population from Fermilab operations during CY-1987 was 5.3 person-rem, or about twice the average of 2.4 person-rem per year from previous operations. Since the exposure is from penetrating radiation, the 50 year dose commitment from operations in 1987 will be the same as the exposure received in 1987. The total release of airborne radioactivity was 81 Ci from venting of air containing short half-life radionuclides. The off-site release of tritium surface water totaled approximately 266 mCi. 43 refs., 11 figs., 10 tabs.
