The Global Fallout Program

The Global Fallout Program database provides information on EML's archived deposition samples and sample measurements. In 1958, the laboratory instituted a global network of sampling sites to determine the global transport and fate of radionuclides released into the atmosphere during the testing of nuclear weapons. A single fission product, strontium-90, was measured in the samples collected during the first 32 years of the program. Strontium-89 was also measured on selected samples. In recent years, the program focused on the global deposition of the naturally occurring radionuclides, beryllium-7 and lead-210. The resulting database is the most comprehensive and extensive record of its kind in the world.

Note:
Development of the archival database was funded by the Office of Nonproliferation Research and Engineering (NN-20) in the Office of Defense Nuclear Nonproliferation, U.S. Department of Energy.

The EML Sample Archives makes available environmental radiological data collected for programs funded through the U.S. Atomic Energy Commission, the U. S. Energy Research and Development Administration and the U. S. Department of Energy. All of these programs have been terminated. The databases were last updated in 1999. No additional data will be added to these databases. Any inquiries about these programs should be made to webmaster@eml.st.dhs.gov.
