There are several types of chemotherapy the use of which depends on the type of cancer‚ various existing disease like diabetes‚ heart disease. Your doctor will choose the type of chemotherapy you need. The use of high-energy radiation from x-rays‚ gamma rays‚ neutrons‚ protons‚ and other sources to kill cancer cells and shrink tumors. Radiation may come from a machine

they are invisible or silent to humans without man-made devices. One small change in a wave can make a world of difference in its entire energy outcome. Waves are very interesting items that effect our lives both positively and negatively. UV. Radiation in sunlight is divided up into three separate parts which are based on wavelengths‚ or more commonly read as energy. These parts are UV-A ‚ UV-B.‚ and UV-C.. UV-A. is 320-400 nanometers. In general shorter wavelengths are more harmful to living organisms

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

Clinical medical physicists are often found in Diagnostic and Interventional Radiology‚ Nuclear Medicine and Radiation Oncology. However‚ areas of specialty are widely varied in scope and breadth e.g.‚ clinical physiology‚ neurophysiology (Finland)‚ and audiology (Netherlands). In the case of research based university departments‚ the scope is even wider and may

valid points concerning the fear of radiation‚ how easily it finds metal guns and knives‚ and the provacy issue that surrounds X-ray technology (5). Throughout this essay Thomas Frank was able to write about the facts surrounding X-rays and keep hs opinion out of the article therefore giving his readers the chance to form their own belief. This essay was written to analyze which belief to choose. Should the public be against the backscatter X-ray because of radiation exposure or is safety against terrorists

A radioisotope is an isotope of an element with different masses‚ whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha‚ beta‚ and gamma rays (Radioactive Isotopes‚ 2017). Radioisotopes have many different uses in the real world‚ but some of the most beneficial uses are in the field of medicine. Technetium‚ more specifically technetium-99m‚ is used in tens of millions of medical diagnostic procedures annually‚ making it the most commonly

Heat Transfer • Thermal radiation = infra-red radiation (beyond red part of visible spectrum) • Surface of sun is 5500 degrees. • Greenhouse effect is the idea that the earth is a greenhouse‚ and the atmosphere is glass that stops substances exiting or entering. • DARK‚ MATT SURFACES emit more radiation than shiny‚ light ones‚ and absorb radiation better. • Conduction: free electrons are given energy where heated and diffuse – this energy is passed on as electrons
