Background Radiation

This 'deceptively simple' question demands a dip into the murky waters of quantum physics.

An experiment designed to answer questions about the radiation environment for manned space missions was launched from Kennedy Space Center today.

Most of the matter in the universe is missing. Scientists believe around 85% of the matter in the cosmos is made of invisible dark matter, which has only been detected indirectly by its gravitational effects on its surroundings.

A lunar safeguard.

The Chernobyl and (to a lesser extent) Fukushima nuclear accidents contaminated large areas of land with low-level radioactivity. After both accidents, huge efforts were taken to decontaminate the affected areas.

Women were given chapatis containing radioactive isotopes as part of trial into iron deficiency

The United States dropped nuclear bombs on Hiroshima and Nagasaki in August 1945, killing hundreds of thousands of people to force Japan's surrender in World War II. A video on social media falsely claims the cities "were never nuked," reasoning that nuclear bombs would have made those cities "uninhabitable for thousands of years."

The Biden administration has agreed to provide Ukraine with depleted uranium shells to equip M1A1 Abrams tanks that the U.S. is sending there. Britain has already delivered tanks to Ukraine equipped with depleted-uranium shells.

What is dark matter? What are neutrinos all about? How do stars work and what was actually going on in the universe in the first minutes after the Big Bang? To answer these questions, you need very sensitive detectors and a lot of skill. Only a few laboratories in the world have been able to perform such sensitive measurements so far. Recently, however, an ultra-sensitive detector has been set up in Germany, which…

The carcinogenic risk from space radiation has always been a health risk issue of great concern during space exploration. In recent years, a large number of cellular and animal experiments have demonstrated that space radiation, composed of high-energy ...

The Senate has until January 3 to pass a bill that would protect the Grand Canyon and its communities from uranium mining.

U.S. Naval Research Laboratory scientists launched the second Strontium Iodide Radiation Instrument (SIRI-2) instrument in December 2021 onboard Space Test Program (STP) Sat-6. SIRI-2, a gamma-ray spectrometer, will demonstrate the performance of europium-doped strontium iodide gamma ray detection technology with sufficient active area for Department of Defense (DoD) operational needs.

In a former gold mine a mile underground, inside a titanium tank filled with a rare liquified gas, scientists have begun the search for what so far has been

"If radioactivity is the thing that makes Vaseline glass cool, it's not what makes Vaseline glass glow."Let's say you're that tchotchkes dealer's ...

QCT delivers far more radiation and exaggerates spinal bone loss, so why is it on the rise?

Depleted uranium is about 40% less radioactive than natural uranium, but it's still toxic

The free how-to dispels myths and minimizes the hazards of hunting and hoarding these special specimens.

Long gone are the days when astronomers only studied the skies with simple optical telescopes. Today, unveiling the mysteries of the Universe involves ever-larger and more complex facilities that detect things like gravitational waves and different forms of electromagnetic radiation – the spectrum o...

None of these are legit, even though they were shared widely on social media. CLAIM: Climate, weather or meteorological events that we would classify as...
