Radioactive sources contain radioactive material of a particular radionuclide (an unstable form of an element emitting radiation), which can vary based on the application for which the source was ...

Congress asked the National Academies to review the civilian uses of radiation sources that contain radionuclides and the potential replacements for sources that pose a high risk to public health or ...

Synchrotron radiation sources generate highly brilliant light pulses, ranging from infrared to hard X-rays, which can be used to gain deep insights into complex materials. An international team has ...

How to keep stray radiation from 'shorting' superconducting qubits; a pair of studies shows where ionizing radiation is lurking and how to banish it. Now is the time to banish low-level radioactive ...

Get an x-ray, and you get a small dose of radiation to visualize your bones and body structures to help you medically. Buy a smoke detector, you’re inviting a tiny source of radiation, americium-241, ...

Sri Lanka is committed to enhancing its national programme to strengthen the radiation protection of workers, according to a recent IAEA review mission. The team of experts found that dose monitoring ...

Cosmic space is filled with continuous, diffuse high-energy radiation. To find out how this energy is produced, the scientists behind ESA’s Integral gamma-ray observatory have tried an unusual method: ...

Radiation therapy is a treatment that uses high doses of radiation to damage cancer cells, either killing them or slowing their growth. Unlike the low-dose radiation used in X-rays to see inside the ...

Ultraviolet light is one of the most familiar cancer risks on Earth, yet it still behaves like a slow, silent explosive in ...
