... natural environment and the cosmic radiation coming from space. Scientists estimate that around 100,000 cosmic ray neutrons and 400,000 secondary cosmic rays penetrate our bodies every hour. Additionally, around 200,000,000 gamma rays which are emitted from the ground also pass through our bodies every...

...; and on the type of radiation emitted. Alpha particles, beta particles (electrons) and gamma rays all damage materials in different ways. But the important point is that they all carry energy, which they lose in passing through matter. It is the transfer of this energy that causes the damage. The same...

.... Indeed, gamma radiation is one of the few phenomena which can penetrate casing and wellbore fluids and be easily detected in-situ. Subsequently, gamma ray emitting tracers have been used as a diagnostic tool in the petroleum industry for quite some time. Production logging practices have routinely...
