Among the most fascinating phenomena are gamma rays, the most energetic form of electromagnetic radiation. Recently, ...

That isn’t the only way to measure gamma radiation, though, and [Alan] has a great circuit to measure even relatively weak radiation sources. It uses a very small photodiode, and draws so little ...

Gamma rays originate from a variety of sources in both the Marvel Universe and the real world. Primary among non-fictional cosmic gamma-ray sources, are supernovas, neutron stars, and gamma-ray ...

The team tested the battery prototype with cesium-137 and cobalt-60, common radioactive byproducts of nuclear reactors. Using cesium-137, the battery produced 288 nanowatts of power, while cobalt-60 ...

Gamma rays can be directed through the body to target tumours that cannot be treated with conventional surgery. The positioning and the intensity of the gamma ray sources are carefully calculated ...

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.

The isotope used must: be a source of gamma rays so that they pass out through the body to be detected by the gamma camera or GM tube; have very short half-lives - sources used typically have half ...
