What are the safe ways to test nuclear energy? In terms of human exposure, the increased incidence of thyroid cancer in many areas of the world (heavily affected by radioactive contamination with radionuclide 131I) is one of the worst consequences of nuclear testing. All people born since 1951 have received some exposure to radiation due to consequences related to weapons testing. Some people who received higher doses of radiation may have a higher risk of cancer from this exposure, although scientists at CDC and NCI believe that this risk is small for most people. Your individual dose from fallout will depend on several factors, such as where you lived when you were tested, how much time you spent outdoors, the weather, the amount of milk you drank and the fresh fruits and vegetables you ate, and other individual and personal lifestyle factors.
The consequences of nuclear bomb tests in the 50s and 60s are appearing in the U.S. UU. Honey, according to a new study. Although radioactivity levels are not dangerous, they may have been much higher in the 1970s and 1980s, researchers say.
After World War II, the United States, the former Soviet Union and other countries detonated hundreds of nuclear warheads in aerial tests. The bombs expelled radiocesium, a radioactive form of the element cesium, into the upper atmosphere, and winds scattered it around the world before it fell from the sky in microscopic particles. For example, many more consequences dusted off the U.S. East Coast, thanks to regional wind and rain patterns.
So Kaste and her colleagues, including one of her college students, collected 122 samples of locally produced raw honey from across the eastern United States and tested them for radiocesium. They detected it in 68% of the samples, at levels greater than 0.03 becquerels per kilogram, approximately 870,000 radiocesium atoms per tablespoon. Highest levels of radioactivity occurred in a Florida sample 19.1 becquerels per kilogram. The findings, reported last month in Nature Communications, reveal that, thousands of kilometers from the nearest bomb site and more than 50 years after the bombs fell, radioactive fallout continues to circulate through plants and animals.
Even so, those numbers are nothing to worry about, the U.S. Food and Drug Administration Tells Science. Radiocesium levels reported in the new study fall well below 1200 becquerels per kilogram, the limit for any food safety problem, the agency says. Radiocesium decays over time, so honey in the past probably contained more.
So, while the new study shouldn't raise any alarm about current honey, understanding how nuclear pollutants move remains vital to assessing the health of our ecosystems and our agriculture, says Thure Cerling, a geologist at the University of Utah. We need to pay attention to these things. Don't have access yet? Subscribe to News from Science for full access to breaking news and analysis on research and science policies.
Since the holding of the three conferences on the humanitarian effects of nuclear weapons, the risk of the use of nuclear weapons has increased. Evidence of the harm caused by the use and testing of nuclear weapons acquires renewed importance in a world where the risk of nuclear weapons being used is increasing. Some studies and evaluations, including an evaluation by Arjun Makhijani of the health effects of nuclear weapons complexes, estimate that cancer deaths due to global radiation doses from nuclear test programs in the atmosphere of the five nuclear-weapon States amount to hundreds of thousands. The International Campaign to Abolish Nuclear Weapons (ICAN) is a coalition of non-governmental organizations in one hundred countries that promotes adherence to and implementation of the United Nations Treaty on the Prohibition of Nuclear Weapons.
Evidence of the foreseeable impacts of a nuclear detonation is an integral part of the risk assessment of nuclear weapons. In its preamble, the treaty banning nuclear weapons recognizes the disproportionate impact of nuclear weapons activities on indigenous peoples. Recognizing that even underground tests were causing serious damage, and eager to end the era of nuclear testing, the international community adopted in 1996 the Comprehensive Nuclear-Test-Ban Treaty. Based on research by existing and emerging experts, the meeting aimed to take stock of the environmental consequences of the use and testing of nuclear weapons, as well as the factors driving nuclear risk.
