ENVIRONMENTAL STATUS OF THE HANFORD SITE FOR CY-1975

摘要

Environmental data collected during 1975 showed continued compliance of Hanford operations with applicable State and Federal regulations regarding ambient pollutant levels in the environs. Levels of radioactivity in the atmosphere measured at 21 onsite stations, 17 perimeter stations and 5 dis¬tant stations showed no conclusive observable effect from Hanford operations. Levels of radioiodine, tritiated water vapor, 90Sr, plutonium, and gamma-emitting radionuclides were measured during the year. No apparent differ¬ences between levels measured at onsite, perimeter, and distant stations were detected.
