Estimated ground deposition of cesium-137 from nuclear-weapon fallout 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.

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.
