JON CHASE:'The decay of these unstable elements is known as ionising radiation. 'There are three main types - alpha, beta or gamma. JON CHASE:'Gamma radiation is pure energy, 'but alpha and beta ...
An international collaboration of scientists is now closer to an answer. They succeeded in the measurement of the bound-state ...
After emitting an alpha or beta particle, the nucleus will often still be ‘excited’ and will need to lose energy. It does this by emitting a high energy electromagnetic wave called a gamma ray.
