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 ...

COLLEGE STATION, Texas (KBTX) - The Texas A&M Engineering Extension, also known as TEEX, demonstrated how to identify and locate a radiation source in the middle of a disaster on Friday. 18 students ...

The ionizing radiation symbol, featuring three curved blades emanating from a central point, has been used since 1946 to warn workers, scientists and the public of the presence of radioactive material ...

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 ...

Sources of high-energy cosmic rays in the vicinity of the microquasar V4641 Sag, on the left with energies above a teraelectronvolt, on the right – hundreds of teraelectronvolts. The location of the ...

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 ...

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: ...

Think about a garden where flowers bloom beside nuclear reactors. It sounds impossible, yet it's happening right now. Since the Chernobyl disaster in 1986, scientists have watched in amazement as ...
