Medical researchers use radioactive materials to develop and test the effectiveness of new medicines and treatments. To do this, some researchers use specialized detectors called “tracers” that track how material travels through a person or animal. Tracers show where medicines or treatments interact with the body, so doctors can diagnose and treat disease. There is a special field in medicine called radiopharmaceuticals that focuses on the use of radioactive materials to help treat or cure diseases. The creation and testing of new radiopharmaceuticals requires the use of radioactive materials. Learn more about Nuclear Medicine.

Those agreements authorize individual States to regulate the use of specific radioactive materials within their borders. This includes radioisotopes used in medicine and industry. States that meet these conditions and agree to regulate materials using the same standards as the NRC are called Agreement States.
What is the NRC's role in the National Materials Program?
Toward that end, the NRC retains a leadership and oversight role in the program through the Integrated Materials Performance Evaluation Process ( IMPEP ). In particular, IMPEP ensures uniform nationwide regulation by reviewing the regulatory performance of both the NRC and the States using a common set of performance criteria.

The NRC also cooperates with State regulatory programs by providing technical support and maintaining databases of regulatory information. To facilitate that cooperation, the NRC's regional offices have designated staff, known as Regional State Agreement Officers, who serve as the primary point-of-contact with Agreement States. Similarly, the Regional State Liaison Officers serve as the contacts for non-Agreement States, and for all States in matters involving reactors or other Federal jurisdiction.

If radioactivity is much higher than background level, handling TENORM may cause problems in many industries and transportation.

Brazil nuts are probably the most radioactive food you can eat. They provide 5,600 pCi/kg (picocuries per kilogram) of potassium-40 and a whopping 1,000-7,000 pCi/kg of radium-226. Although the radium is not retained by the body for very long, the nuts are approximately 1,000 times more radioactive than other foods.

Some of these objects may pose a health risk, but most of them are a harmless part of your everyday environment. In almost all cases, you get more exposure to radiation if you take a ride in a plane or get a dental x-ray. Still, it's good to know the sources of your exposure.
What foods contain radon?
This includes potatoes (radioactive french fries), carrots, lima beans and red meat. Carrots, potatoes, and lima beans also contain some radon-226. When you get right down to it, all food contains a small amount of radioactivity. You eat food, so you are slightly radioactive, too.
Is cat litter radioactive?
Cat litter is sufficiently radioactive that it can set off radiation alerts at international border checkpoints. Actually, it's not all cat litter you need to worry about — only the stuff made from clay or bentonite. Radioactive isotopes naturally occur in clay at the rate of about 4 pCi/g for uranium isotopes, 3 pCi/g for thorium isotopes, and 8 pCi/g of potassium-40. A researcher at Oak Ridge Associate Universities once calculated American consumers buy 50,000 pounds of uranium and 120,000 pounds of thorium in the form of cat litter each and every year.

It is more likely to contain alpha-emitting actinides such as Pu-239 which is a fissile material used in bombs, plus some material with much higher specific activities, such as Pu-238 or Po.
Where does radioactive waste come from?
Radioactive waste comes from a number of sources. In countries with nuclear power plants, nuclear armament, or nuclear fuel treatment plants, the majority of waste originates from the nuclear fuel cycle and nuclear weapons reprocessing. Other sources include medical and industrial wastes, as well as naturally occurring radioactive materials (NORM) that can be concentrated as a result of the processing or consumption of coal, oil, and gas, and some minerals, as discussed below.
How much of the UK's nuclear waste is HLW?
HLW accounts for over 95% of the total radioactivity produced in the process of nuclear electricity generation but it contributes to less than 1% of volume of all radioactive waste produced in the UK. Overall, the 60-year-long nuclear program in the UK up until 2019 produced 2150 m 3 of HLW.
How does radioactivity change with time?
The radioactivity of all radioactive waste weakens with time. All radionuclides contained in the waste have a half-life — the time it takes for half of the atoms to decay into another nuclide. Eventually, all radioactive waste decays into non-radioactive elements (i.e., stable nuclides ). Since radioactive decay follows the half-life rule, the rate of decay is inversely proportional to the duration of decay. In other words, the radiation from a long-lived isotope like iodine-129 will be much less intense than that of a short-lived isotope like iodine-131. The two tables show some of the major radioisotopes, their half-lives, and their radiation yield as a proportion of the yield of fission of uranium-235.
What are the health effects of ionizing radiation?
Exposure to radioactive waste may cause health impacts due to ionizing radiation exposure. In humans, a dose of 1 sievert carries a 5.5% risk of developing cancer, and regulatory agencies assume the risk is linearly proportional to dose even for low doses. Ionizing radiation can cause deletions in chromosomes. If a developing organism such as a fetus is irradiated, it is possible a birth defect may be induced, but it is unlikely this defect will be in a gamete or a gamete-forming cell. The incidence of radiation-induced mutations in humans is small, as in most mammals, because of natural cellular-repair mechanisms, many just now coming to light. These mechanisms range from DNA, mRNA and protein repair, to internal lysosomic digestion of defective proteins, and even induced cell suicide—apoptosis
Why is radioactive waste regulated?
The storage and disposal of radioactive waste is regulated by government agencies in order to protect human health and the environment.
What is the front end of nuclear fuel?
Front end. Waste from the front end of the nuclear fuel cycle is usually alpha-emitting waste from the extraction of uranium. It often contains radium and its decay products. Uranium dioxide (UO 2) concentrate from mining is a thousand or so times as radioactive as the granite used in buildings.
