According to the radioactive element and the specific site conditions, bacteria can enzymatically immobilize radionuclides directly or indirectly. Their redox potential is exploited by some microbial species to carry out reductions that alter the solubility and hence, mobility, bioavailability and radiotoxicity. This waste treatment technique ...
2007 ISO radioactivity danger symbol intended for IAEA Category 1, 2, and 3 sources defined as dangerous sources capable of causing death or serious injury [1]. This article lists notable civilian accidents involving radioactive materials or involving ionizing radiation from artificial sources such as x-ray tubes and particle accelerators.
Radioactive iodine-131 is a common fission product; it was a major component of the radioactivity released from the Chernobyl disaster, leading to nine fatal cases of pediatric thyroid cancer and hypothyroidism. On the other hand, radioactive iodine is used in the diagnosis and treatment of many diseases of the thyroid precisely because of the ...
Climate change increasingly threatens some of the nation's most sensitive sites, including research laboratories, military facilities and power plants with radioactive material. Many sites are ...
One of the most dangerous radioactive materials is plutonium, said Edwin Lyman, director of nuclear power safety at the Union of Concerned Scientists. It can cause cancer, is most dangerous when ...
During this event, radioactive material was transported by groundwater across borders into neighboring countries. In Belarus, just north of Chernobyl, about 250,000 hectares of previously usable farmland were held [clarification needed] by state officials until deemed safe. [162] Off-site radiological risk may be found in the form of flooding.
The intake of radioactive iodine was calculated based on the radioactive caesium intake and other factors: the airborne iodine-to-caesium ratio on the days that the people worked at the reactor compound and other data. For one worker a reading was found of more than 1,000 millisieverts. [125]
A clean-up crew working to remove radioactive contamination after the Three Mile Island accident. Nuclear safety in the United States is governed by federal regulations issued by the Nuclear Regulatory Commission (NRC). The NRC regulates all nuclear plants and materials in the United States except for nuclear plants and materials controlled by ...
