Gamma Ray Diagram. P43423a01324 13 turn over b gamma radiation from cobalt 60 can be used to destroy tumours. After emitting an alpha or beta particle the nucleus will often still be excited and will need to lose energy.
Ecg main features. P43423a01324 13 turn over b gamma radiation from cobalt 60 can be used to destroy tumours. Gamma ray electromagnetic radiation of the shortest wavelength and highest energy.
It shows also that two of these gamma rays are emitted virtually 100 of the time.
The degree of attenuation depends upon the number density of atoms in the material and this is related to the density of the material. One can see that a detection threshold of approximately 1 kev is achieved with this detector. Many radioactive isotopes decay by particle emission. Many gamma ray irradiators have been built and it is estimated that about 200 are currently in operation in member states of the international atomic energy agency iaea.
