http://nucleardata.nuclear.lu.se/toi/ WebGamma rays are photons (particles of light) with energies ranging from 104 ev (electron volts) to 10 7 ev. Gamma ray logs are used to detect in situ radioactivity from naturally occurring radioactive materials such as potassium, thorium, and uranium. In general, shale contains more radioactive materials than other rock types.
