Lightning produces afterglow of gamma radiation

Lightning can produce X-rays and gamma radiation. In the past, researchers thought that this phenomenon only lasted for a very short time, about one ten-thousandth of a second. However, the ionizing radiation of lightning ...

Explaining why the universe can be transparent

Two papers published by an assistant professor at the University of California, Riverside and several collaborators explain why the universe has enough energy to become transparent.

Chernobyl, three decades on

It was 30 years ago that a meltdown at the V. I. Lenin Nuclear Power Station in the former Soviet Union released radioactive contaminants into the surroundings in northern Ukraine. Airborne contamination from what is now ...

Focused laser power boosts ion acceleration

An international team of physicists has used carbon nanotubes to enhance the efficiency of laser-driven particle acceleration. This significant advance brings compact sources of ionizing radiation for medical purposes closer ...

Study could change nuclear fuel

The adverse effects of radiation on nuclear fuel could soon be better controlled thanks to research involving UT's College of Engineering.

Space travel is a bit safer than expected

Analysis of data from the MATROSHKA experiment, the first comprehensive measurements of long-term exposure of astronauts to cosmic radiation, has now been completed. This experiment, carried out on board and outside of the ...
