The full impact of the Japanese nuclear crisis remains to be seen, but the health risks posed by radioactive contamination are well documented. In 2006, the National Academies of Science issued a definitive report on radiation exposure that concluded that even low levels of radiation can cause human health problems, including cancer, heart disease, or immune disorders. A major avenue for exposure to radioactive contamination comes through food and water. Decades after the Chernobyl accident, the United Kingdom still maintains restrictions on large sectors of the countrys sheep production because radioactive cesiumdispersed through wind and rainstill contaminates grazing lands. The U.S. imported around 150 million pounds of food from Japan in 2010, a small percentage of what Americans consumed, but not an insignificant amount. Imports from Japan included nearly 600,000 pounds of crab and anchovies and nearly 5 million gallons of bottled water, soft drinks and other non-alcoholic beverages containing water, products that may be potentially higher risk if contamination continues to spread to the ocean and fresh water sources.
