For sometime after the accident, EPA scientists measured radioactivity in the Black Sea and Kiev Reservoir in cooperation with the former Soviet Union. returned to their March 1986 levels of 0.1 pCi/m 3 or lower.ĮPA sent experts to Europe to monitor and assess levels of radioactivity around U.S. In July 1986, monthly maximum air beta levels across the contiguous U.S. The slideshow below shows the fluctuations in air beta levels across the contiguous U.S. Although radioactivity levels were somewhat elevated, they were well below levels requiring protective actions. RadNet's predecessor, the Environmental Radiation Ambient Monitoring System (ERAMS), first detected radiation from the accident at ground level on the West Coast one week after the accident. Arranged daily press conferences to keep the public up-to-date and to give EPA an opportunity to answer the public's concerns.Established an information center to gather and distribute facts and data about the accident.Established a group to provide advice on preventing contamination of the food supply and protecting public health.Increased the Environmental Radiation Ambient Monitoring System (abbreviated ERAMS, now RadNet) sampling and analysis frequency.The Agency immediately took several steps: In response to Americans' concern about potential health effects in the United States, the White House assigned the responsibility for leading the U.S.

Almost no data were available on the extent of radioactive fallout fallout Radioactive particles that fall to the ground after a nuclear explosion. in Europe and the rest of the world. In the days following the accident, the Soviets released little data on the severity of the accident.
