Wednesday, December 17, 2008. Stochastic vs Non-Stochastic Effects. I was asked a question about the difference between stochastic and non-stochastic effects of radiation, and I decided to make my answer public. Everyone is concerned about how radiation dose affects their body. The way the human body responds to radiation dose (dose-response) is classified into two broad categories of health effects: stochastic. Non-stochastic is also called deterministic. Teratogenic mutations are caused by exposure of ...

Saturday, September 27, 2008. A Geiger Muller counter is used to detect Radioactivity. Radioactivity- Alpha and Beta Particles.Gamma Rays. An Alpha particle is like the nucleus of the Helium atom. It has two neutrons and two protons bound together. Because of its composition, it has a much greater mass than the Beta particle which has the mass of an electron. Alpha particles have minimal penetrating ability. They are absorbed by a sheet of paper. However, their ability to ionize is extremely high. Beta p...

Thursday, March 12, 2009. The x-ray circuit is composed of two major secondary regions or circuits:. 1 the filament circuit (outlined in red on the diagram below), and. 2 the high voltage or high tension circuit (outlined in blue). The filament circuit gets its power supply directly from the autotransformer and supplies current to the filament of the x-ray tube. The major components of the filament circuit are:. 1 the mA selector. 2 the focal spot selector. 3 the step-down transformer. Is a switch that a...
