In addition to EPA’s RadNet system, the U.S. The EPA’s system has not detected any radiation levels of concern. Environmental Protection Agency RadNet system is designed to protect the public by notifying scientists, in near real time, of elevated levels of radiation so they can determine whether protective action is required. WASHINGTON – The United States Government has an extensive network of radiation monitors around the country and no radiation levels of concern have been detected. JOINT EPA/DOE STATEMENT: Radiation Monitors Confirm That No Radiation Levels of Concern Have Reached the United States Safety is a critical element of the Department of Energy's mission, and to ensure that we fully evaluate all available information from our assessment of Department of Energy facilities and the lessons-learned from our continuing review of the Japan event, Deputy Secretary Poneman is convening a Department of Energy Nuclear Safety Workshop on June 6 - 7, 2011, in Arlington, Virginia. The recent events impacting the Fukushima Daiichi nuclear power station in Japan demonstrated that, while unlikely, a worst-case scenario event - an event beyond the design basis - is not impossible. For a link to the joint monitoring data posted on May 6, visit the MEXT webpage.įile footage of the Aerial Measuring System This data that was collected and analyzed jointly with the Government of Japan's Ministry of Education, Culture, Sports, Science and Technology (MEXT). Today, the Department provided the following update on the information gathered by the AMS. Department of Energy released data recorded from its Aerial Measuring System as well as ground detectors deployed along with its Consequence Management Response Teams. Check back in the coming month for information about this survey. Click on a point to see a chart of the measurements collected in that area.Ī small NNSA team returned to Japan this month to provide further data collection and analysis support as the Japanese plan another aerial monitoring campaign. The above map visualizes the field measurements collected by the Energy Department in the area around the nuclear power station. The raw data collected and analyzed from those flights and surveys are now available for public download and review on here, here, here, and here. NNSA scientists also collected thousands of field and soil samples. Air Force aircraft operated out of Yokota Air Base to collect data during more than 500 flight hours. NNSA also loaned the Government of Japan an aerial radiation detection system to augment its capability.įor 10 weeks following the natural disaster, NNSA scientists utilized U.S. The Energy Department and NNSA have provided ongoing assistance to Japan to support dose assessment through collaboration on data analysis and quality control. In the seven months since the March 11 earthquake and tsunami in Japan, the Energy Department and the National Nuclear Security Administration (NNSA) have worked diligently to support the government of Japan as it collects, monitors and analyzes the data from aerial and ground-based surveys measuring radiation levels associated with material deposited on the ground surrounding the Fukushima Daiichi nuclear power station. The teams are based out of Las Vegas, Nev., Washington, D.C., and Aiken, S.C. These trained experts are in charge of maintaining a state of readiness to respond to a radiological emergency at any time. The AMS uses specialized radiation detection systems mounted in aircraft to provide real-time measurements of ground contamination. The NNSA maintains the Aerial Measuring System (AMS) capability to respond to radiological and nuclear incidents in the U.S. The meeting was held at the NNSA Nevada Site Office in Las Vegas, Nev. In attendance were scientific experts from the NNSA Consequence Management and Aerial Measuring System programs. ![]() The purpose of the analyses is to obtain a better understanding of the radiological conditions during the early response period. The results from these analyses can aid in efforts to model the doses that may have been incurred during the incident. Scientists from the Japanese Atomic Energy Agency (JAEA) met with colleagues from National Nuclear Security Administration (NNSA) to work on on-going aerial and ground monitoring efforts following the accident at the Fukushima Daiichi nuclear power plant in March 2011.Ī key element of the meeting was the discussion of detailed analysis techniques which could be applied to the data collected in Japan by the NNSA response teams during the first month following the earthquake and tsunami. ![]() ![]() NNSA Meets with Japanese Scientists to Discuss On-Going Fukushima Work
