A radiation detector is a device used to detect, track, or identify high- energy particles, such as those produced by nuclear decay, cosmic radiation, and reactions in a particle accelerator. Modern detectors are also used as calorimeters to measure the energy of detected radiation.
There are many radioactive substances with very different properties. Some are gaseous, others liquid or solid. Some are highly chemically reactive, others inert. As radioactivity depends only on properties of the …
Alpha, Beta, and Gamma Research begun by people such as New Zealander Ernest Rutherford soon after the discovery of nuclear radiation indicated that different types of rays are emitted. Eventually, three types were distinguished and named alpha (alpha), bet a (beta) and gamm a (gamma) because, like x-rays, their identities were initially unknown.
That''s right, bananas contain naturally occurring radionuclides — radioactive potassium-40, to be exact — which, according to the EPA, means they can emit .01 millirem (0.1 microsieverts). So, eating a banana actually presents more radiation exposure than if you were standing next to a spent nuclear fuel dry cask or nuclear power …
An atomic battery, nuclear battery, radioisotope battery or radioisotope generator is a device which uses energy from the decay of a radioactive isotope to generate electricity. Like nuclear reactors, they generate electricity from nuclear energy, but differ in that they do not use a chain reaction .
Betavoltaic batteries contain radioactive emitters and semiconductor absorbers. As the emitter material naturally decays, it releases beta particles, or high …

We conclude that all smoke detectors are not radioactive, but some contain Americium which has a long half-life and emits low levels of radiation. If you are still concerned about the radiation levels from your smoke detector, you can purchase a model that does not contain any radioactive material.
Radioactivity occurs when an atom has an excess of energy, mass, or both, making its nucleus unstable. To reach a lower, more stable energy level, it releases energy in the form of radiation. This radiation can be emitted as particles or electromagnetic waves, depending on the nature of the decay. ...
Frequent Questions: Radiation Sources | US EPA
Lithium compounds in finished batteries generally contain lithium in ionic form, which is less reactive than lithium metal and presents fewer flammability hazards. Exposure to ionic lithium, which is present in both anode material and electrolyte salts, has both acute and chronic health effects on the central nervous system.
With alternate, sustainable, natural sources of energy being sought after, there is new interest in energy from radioactivity, including natural and waste radioactive materials. …
Sealed radioactive sources such as the sources involved in the Indian accident are used widely in medicine, indus-try, and agriculture. The radioactive substance within a source is sealed within a protective container. Radioactive substances emit energetic
4 Among its many activities to improve the safety and security of sealed sources, the IAEA has been investigating the root causes of major accidents and incidents since the 1980''s and publishes findings so that others can learn from them. There are growing ...

In the field of microelectromechanical systems (MEMS), nuclear engineers at the University of Wisconsin, Madison have explored the possibilities of producing minuscule batteries which exploit radioactive nuclei of substances such as polonium or curium to produce electric energy. As an example of an integrated, self-powered application, the researchers have created an oscillating cantilever beam that is capable of consistent, periodic oscillations over very long time periods wi…

Carbon-14 and other naturally occurring radioactive substances in our bodies contribute to the background radiation we receive. The small number of decays per second found for a kilogram of carbon in this example gives you some idea of how difficult it is to detect (^{14}C) in a small sample of material.
