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 ...

Terahertz waves, known as non-ionizing radiation, can turn into ionization radiation when sufficiently many terahertz photons are focused in space and time. A team led by scientists in Korea and the U ...

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 ...

During flights, airplane crews are exposed to cosmic radiation, yet regulatory protections for these workers are insufficient ...

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 ...

The IAEA’s expertise in medical physics and dosimetry is enhancing the capacities of countries around the globe to use ionizing radiation in medical procedures safely and effectively, the Scientific ...

Bob Benjamin was observing the Milky Way when he noticed something odd. The professor in the University of Wisconsin-Madison's astronomy department, and co-author of a new study, saw a red, tilted ...

This chapter presents models that allow one to estimate the lifetime risk of cancer resulting from any specified dose of ionizing radiation and applies these models to example exposure scenarios for ...

When cells are exposed to ionizing radiation, more destructive chain reactions may occur than previously thought. An international team led by researchers has now observed intermolecular Coulombic ...
