| gamma rays |
Part of the electromagnetic spectrum similar to X-rays but with shorter wavelengths and greater penetrative power (they can only be stopped by layers of lead or thick concrete).

| gamma rays |
High-energy electromagnetic radiation emitted by certain radionuclides when their nuclei transition from a higher to a lower energy state. These rays have high energy and a short wave length. All gamma rays emitted from a given isotope have the same energy, a characteristic that enables scientists to identify which gamma emitters are present in a sample. Gamma rays are very similar to x-rays.

| gamma rays |
Gamma rays are essentially light packages or "photons" which are emitted from some unstable atoms which have just undergone a transformation by emitting a charged particle. Depending on the radioisotope, there may be one or several gamma rays emitted with differing energies. In addition the probability or frequency of their emission can vary from 100% to well under 1% as each transformation or decay occurs. ...
