II. Basic Physics of Ionizing Radiation
... • EM radiation with wavelengths shorter than 100 nanometers can remove electrons from the outer atomic shells. • This process produces ions. • Ions can interact with living tissue to produce biological damage. • A major source of ionizing radiation is nuclear transformation. ...

Radiation Safety - 7
... 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, which cause it to become luminescent in proportio ...

John Gofman
John William Gofman (September 21, 1918 – August 15, 2007) was an American scientist and advocate. He was Professor Emeritus of Molecular and Cell Biology at University of California at Berkeley.Gofman pioneered the field of clinical lipidology, and was honoured with the title of ""Father of Clinical Lipidology"" by the Journal of Clinical Lipidology in 2007. With Frank T. Lindgren and other research associates, Gofman discovered and described three major classes of plasma lipoproteins, fat molecules that carry cholesterol in the blood. The team he led at the Donner Laboratory went on to demonstrate the role of lipoproteins in the causation of heart disease.Gofman's earliest research was in nuclear physics and chemistry, in close connection to the Manhattan Project. He co-discovered several radioisotopes, notably uranium-233 and its fissionability ; he was the third person ever to work with plutonium, and, having devised an early process for separating plutonium from fission products at J. Robert Oppenheimer’s request, he was the first chemist ever to try and isolate milligram quantities of plutonium.In 1963, Gofman established the Biomedical Research Division for the Livermore National Laboratory, where he was on the cutting edge of research into the connection between chromosomal abnormalities and cancer.Later in life, Gofman took on a role as an advocate warning of dangers involved with nuclear power. From 1971 onward, he was the Chairman of the Committee for Nuclear Responsibility. He was awarded the Right Livelihood Award for his work on the effects of the Chernobyl disaster's low-level radiation exposure on the population.
