The epoch of cosmic reionization marks a fundamental phase transition in the Universe when the pervasive neutral hydrogen was ionized by the first luminous sources. Central to this process is the ...

The radiation inside a microwave oven isn't the same kind associated with X-rays, and a properly working machine keeps ...

A new congressionally mandated National Academies report is bringing renewed attention to those questions, recommending a ...

Our new study of the nearby starburst galaxy Haro 11 has shown that strong X-ray-emitting superwinds may be a key mechanism enabling galaxies to leak ionizing radiation, which is believed to have ...

For a human, experiencing a mere five grays (Gy) of ionizing radiation for just a few minutes can be lethal. But the bacterium Deinococcus radiodurans is made of tougher stuff. In liquid culture ...

Recent release of the waste water from Japan's Fukushima nuclear disaster stirred apprehension regarding the health implications of radiation exposure. Classified as a Group 1 carcinogen, ionizing ...

A recent study published in the BMJ evaluated the effects of long-term exposure to low-dose ionizing radiation on cancer mortality. Study: Cancer mortality after low dose exposure to ionising ...

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 ...

Detecting radiation is key to technologies ranging from particle accelerators and scientific instruments to medical imaging ...

Most people interpret radiation as a bad thing—but it isn’t always. In fact, radiation is a very normal phenomenon. For now, let’s just say that radiation is when an object produces energy. When a ...
