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

electricity. In addition‚ radiation has uses in such areas as agriculture‚ space exploration‚ law enforcement‚ geology and many others. 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

Diagnostic Imaging: X-Ray Diagnostic Imaging is medical tools used by doctors to see inside our bodies without actually opening the body. Diagnostic imaging can involve the use of radiation which could be dangerous if exposed to large amounts of. Diagnostic imaging allows doctors to find tumors‚ broken bones‚ pneumonia‚ etc. In general‚ diagnostic imaging is very helpful. X-Rays: This was one of the first types of diagnostic imaging. It uses radiation called Electromagnetic Waves. These

Examples of ionizing radiation include: • alpha particles • beta particles • neutrons • gamma rays • x-rays Non-ionizing radiation does not have enough energy to ionize atoms in the material it interacts with. Examples of non-ionizing radiation include: • microwaves • visible light • radio waves • TV waves • Ultraviolet radiation (except for the very

When “The Pedestrian” by Ray Bradbury was written‚ mankind had made great progress with inventions such as the television. However‚ with these amazing technological advances‚ children become more prone to be in front of a screen rather than playing outside. In the story‚ Bradbury wrote about the effects of these improvements. Through imagery‚ he created the illusion of isolation through lonely‚ unhappy‚ and descriptive language. This leaves readers shocked with the realism of the story. Bradbury

understanding of their condition. One benefit of digital x-ray has become common in most hospitals and clinics is that it creates a digital picture archive within hospital communication systems allowing doctors to have easy access their patient images. It is designed to replace film in just about any existing X-ray imaging equipment used today and does not require film developers‚ processing chemicals or storage space. Another benefit is that digital X-ray images can be obtained almost instantly and their

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

At just 30 years old‚ Ray Hinton was convicted of killing two restaurant managers and was sentenced to die in Alabama. At the age of 57‚ the United States Supreme Court‚ overturned that death sentence‚ which allowed him to have a new trial that resulted in his exoneration.
