... 2 major nuclear accidents have occurred which leads to radioactive nuclei circumnavigating the globe. It is estimated that the 1986 Chernobyl melt down will have caused 20 million cases of human cancer by the year 2050. Note: Radioactive gases decay fast and are stored until levels are save and are ...

... OPTICALLY STIMULATED LUMINESCENCE (OSL) DOSIMETER OSL’s use two thin Al2O3 strips which when exposed to radiation record Photons (X & d Rays) in the 5 keV / 40 MeV range & Beta Particles in the 150 keV / 10 MeV range. During analysis, the Al2O3 is stimulated with selected frequencies of laser light ...

Background radiation
Background radiation is the ubiquitous ionizing radiation that people on the planet Earth are exposed to, including natural and artificial sources.Both natural and artificial background radiation varies depending on location and altitude.
