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)

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

X-rays are electromagnetic rays that pass through the patient allowing the radiographer to see inside the patient due to the different types of attenuation of the body. These x-rays can cause harm to a person if used improperly or overexposed. The way they do that is through ionizing radiation. Ionizing radiation is when the x-ray particle goes into the body and they carry enough energy to remove an electron from
