Cesium 137 from nuclear weapon testing fallout (1995 figures)
Philippe Rekacewicz, UNEP/GRID-Arendal
Nuclear explosions - especially the atmospheric tests in the Arctic and from US, UK and Chinese tests at other sites in the world - are the primary source of radioactive contamination in the Arctic. With the times needed for decomposition of nuclear fallout, these higher radiation levels subsists for longer times.
