applications of x-ray Introduction: X-radiation (composed of X-rays) is a form of electromagnetic radiation. X-rays have a wavelength in the range of 0.01 to 10 nanometers‚ corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×1016 Hz to 3×1019 Hz) X-rays up to about 10 keV (10 to 0.10 nm wavelength) are classified as "soft" X-rays‚ and from about 10 to 120 keV (0.10 to 0.01 nm wavelength) as "hard" X-rays‚ due to their penetrating abilities.[3] Hard X-rays can penetrate some

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
