Estimated ground deposition of cesium-137 from nuclear-weapon fallout
The graph shows the estimated ground deposition of cesium-137 from nuclear weapon testing fallout. Cesium- 173 deposition from nuclear- weapon fallout have severe effects on human health. Based on estimaed doses to the Arctic population, nuclear weapon fallout will contribute to 750 additional cases of fatal cancer.

Cesium 137 from nuclear weapon testing fallout (1995 figures)
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.
