Earth is naturally radioactive, so we are all constantly exposed to a small amount of background radiation. Additionally, gamma rays are used in medicine, including in radiotherapy-based cancer ...

Called electromagnetic radiation, such waves travel at the speed of light and bring us almost all the information we have about the universe. Gamma rays are much shorter in wavelength than visible ...

It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma radiation does not consist of particles but as short wavelength, high energy electromagnetic radiation emitted ...

“Peat soils have a unique ability to block this type of naturally occurring radiation, drastically reducing the number of gamma rays detected by the sensor mounted on the Tellus aircraft when ...
