Environmental impact of nuclear power materials decay, they release particles that can damage the body and lead to cancer, particularly cesium-137 and iodine-131. In the Chernobyl disaster, releases of cesium-137 contaminated land. Some communities, including the entire city of Pripyat, were abandoned permanently. One news source reported that thousands of people who drank milk contaminated with radioactive iodine developed thyroid cancer. The exclusion zone (approx. 30 km radius around Chernobyl) may have significantly elevated levels of radiation, which is now predominantly due to the decay of cesium-137, for around 10 half-lives of that isotope, which is approximately for 300 years. Due to the bioaccumulation of
Antibiotic use in livestock government regulates antibiotic use in the cattle production industry. China produces and consumes the most antibiotics of all countries. Antibiotic use has been measured by checking the water near factory farms in China as well as through animal feces. It was calculated that 38.5 million kg (or 84.9 million lbs) of antibiotics were used in China's swine and poultry production in 2012. The abuse of antibiotics caused severe pollution of soil and surface water in Northern China. In 2012, U.S. News & World Report described the Chinese government's regulation of antibiotics in livestock production as "weak". On the UK 5
