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

concepts we have learned throughout chapter one presented in the film. Ray Kinsella hears voices speaking to him on the farm and this concept is listening to God. Ray also responds to God’s call which is the concept of Responding to God. Ray shows a great amount of Sacramental blindness also when he gets frustrated and asks what is in it for him. Ray was in the fields working one day when he heard a sudden voice talk to him. Ray thinks he is going insane and asks his wife sitting on the porch if she

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

with an electric current flow in a partially evacuated glass tube known as a cathode-ray tube. 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)
