The Surface Air Sampling Program

The Surface Air Sampling Program (SASP) database provides information on EML's archived air filter samples and sample measurements. The program was established in 1957 to track the global dispersion of radioactive debris resulting from atmospheric testing of nuclear bombs. Air filter samples were collected at locations throughout the world and analyzed for nuclear debris. In the 1980's, the program focused on the global distributions 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.
