The cosmic pinwheel that astronomers feared could one day shower Earth with lethal gamma rays may not be as dangerous as once ...

Changing these interactions can lead to different chemical reactions and malfunctioning cells in our bodies. Gamma rays are a particularly damaging form of ionizing radiation because their high ...

That isn’t the only way to measure gamma radiation, though ... The detector circuit uses a miniature solar cell and a JFET wired up in a small brass tube to block most of the light and to ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film ...

A new study explains how thunderstorm electric fields produce strong gamma‐ray glows with oscillating gamma‐ray rates, and that these oscillations develop into intense pulse trains that closely ...

Nuclear power has long been a reliable energy source, supplying nearly 20% of electricity in the United States. While it does ...

"This field did not exist before 1989 when the first gamma ray source was detected. At that point, we knew of four sources in the world," said Dave Kieda, professor in the Department of Physics ...

Our skin and mucous membranes protect us like vigilant sentinels against the onslaught of harmful pathogens. This extraordinary defense owes its strength to epithelial cells—specialized tissues woven ...

This site presents the energy and photon intensity of gamma rays as seen in thermal-neutron capture in two tables, one in ascending order of gamma energy and a second organized by Z, A of the target.

For that, you need something like this gamma-ray spectroscope. Dubbed the Pomelo by [mihai.cuciuc], the detector is a homebrew solid-state scintillation counter made from a thallium-doped cesium ...

The ionizing power of gamma rays is low, but they are difficult to ... because it is highly ionizing and is easily absorbed by cells; beta and gamma radiation are not as dangerous because they ...
