A continuous monitoring program has been maintained since 1951 (before plant start-up) to determine concentrations of radioactive materials in a 1200-square-mile area outside SRP. Although some gaseous and liquid radioactive materials are discharged from SRP operations, concentrations and doses to the surrounding population continued to be far below levels considered significant from a public health viewpoint. The concentration of radioactivity added by SRP to its environs during 1976 was too small to be distinguished from natural background radiation and fallout from worldwide nuclear weapons tests. Beta activity in particulate air filters was about 1.5 times the 1975 level and was due entirely to global fallout. This concentration, both at the plant perimeter and 25 miles away (0.07 pCi/m/sup 3/), represents 0.07% of the Concentration Guide (CG) (defined in the Applicable Standards section which follows). Tritium oxide in air at the plant perimeter was greater than in air at more distant locations; the average concentration at the plant perimeter (50 pCi/m/sup 3/) was less than 0.1 of the Concentration Guide. Tritium, cesium-137, and strontium-90 were the only radionuclides of plant origin detectable in river water by routine analyses.Special research programs using ultra-low-level techniques have detected trace quantities of other radionuclides of plant origin. Radioactive materials in river fish also continued very low. Monitoring in a five-square-mile swamp bordering the Savannah River immediately below the SRP boundary has shown radioactivity (primarily cesium-137) above the natural background level in soil and vegetation.
