The X-Ray imaging system has one function‚ and that is to provide a constant flow of electrons that are strong enough to produce and x-ray beam to create an image. There are many different sizes and types of imaging systems but no matter what system you use‚ every type will have three main sections. Those sections are the control console‚ the high voltage generator and the x-ray tube. The x-ray tube is located in the exam room‚ the control console is located in an adjoining room that is separated

Food irradiation is a food safety technology that can eliminate disease-causing germs from foods. Like pasteurization of milk‚ and pressure-cooking of canned foods‚ treating food with ionizing radiation can kill bacteria that would otherwise cause food borne disease. The process can also control insects and parasites‚ reduce spoilage‚ and inhibit ripening and sprouting. (5) The effects of irradiation on the food and on animals and people eating irradiated food have been studied extensively

He noticed that‚ whenever the tube was in operation‚ a piece of barium platino cyanide in line with it gave off light. According to Roentgen “the interaction of electrons striking the tube’s glass wall formed an unknown radiation that caused the fluorescence”. He called the mysterious phenomenon X radiation‚ or X rays. Further experiments revealed that X radiation produces an image on photographic plates

Food Irradiation: Good idea or bad? Food irradiation is using gamma rays‚ x-rays‚ or high voltage electron on the foods we eat to kill parasites and bacteria that will allow food to last longer‚ delay sprouting‚ increase the shelf life‚ and make food safer to eat. This is because these short wavelengths will damage and the microorganisms that spoil and deteriorate food beyond repair. To use food irradiation‚ you need two things a source or radiant energy and a way to confine the energy. (1)

Some of the greatest medical advancements in the modern age involve the use of many different types of radiation. Radiation therapy is used in treating multiple different types of cancer‚ and radiation from certain elements are put in X-ray tubes to save countless lives and prevent permanent injury wherever possible. Many organisations also use it for security‚ as well as the general use in the everyday home. These advancements and many more were based on the work of Marie Curie‚ renowned female

However‚ in the medical industry‚ radiation is used for x-rays‚ therapeutic uses‚ and in nuclear medicine procedures. The most common of these medical procedures involve the use of x-rays — a type of radiation that can pass through our skin. When x-rayed‚ our bones and other structures cast shadows because they are denser than our skin‚ and those shadows can be detected
