Thanks to stints as an X-ray technician in my early 20s followed by work in various biology labs into my early 40s, I’ve been classified as an “occupationally exposed worker” with regard to ionizing ...

What do the Curie couple, Henrie Becquerel, Louis Harold Gray, and Ralf Sievert have in common? These radiation pioneers defined the way we measure ionizing radiation. Pierre and Marie Curie created ...

Scientists at the National Institute of Standards and Technology (NIST) have developed a new technology for measuring how radiation damages DNA molecules. This novel technique, which passes DNA ...

Researchers have found a new way to measure radiation damage in materials, quickly, cheaply and continuously, using transient grating spectroscopy. Materials exposed to a high-radiation environment ...

Some types of cancer and other diseases are treated with a drug containing radioactive material that targets the tumor. However, the drug can also be deposited in healthy organs, potentially damaging ...

For the first time since 1981, when China deployed the DF-5 intercontinental ballistic missile, a new state has gained the capability to target the United States with a nuclear weapon. On July 4 and ...

This paper presents a novel digital instrument designed for measuring radiation doses in Ethanol-Chlorobenzene (ECB) dosimeters, based on oscillometry method. ECB dosimeters are versatile tools for ...

Radiation, used to treat half of all cancer patients, can be measured during treatment for the first time with precise 3D imaging developed at the University of Michigan. By capturing and amplifying ...

The US Food and Drug Administration (FDA) has finalized guidance detailing the types of data and study considerations necessary to support the approval of diagnostics intended to measure levels of ...

Researchers have developed a better bolometer, a device for measuring electromagnetic radiation. The new technology is faster, simpler, and covers more wavelengths. Bolometers, devices that monitor ...

NASA wants to build a permanent base on the moon by the 2030s — a place astronauts could stay for extended visits at the lunar south pole. But a new study found that any astronauts who go there would ...
