well known theories, which have not always been as such. New evidence arises quickly and is contested just as fast, leading to great debate, but also to great revelations into the true nature of an effect as complicated as the oxygen effect in radiobiology.. A brief history of the study of the oxygen effect will give some insight into the intensity of study and the ever changing attitudes and theories surrounding it. The first acknowledged study was made by Swartz in 1912. His contribution was realized
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
Computed tomography (CT) offers the advantages of 3D imaging with volumetric and multi-planar reconstructions (21, 22). Given the relatively high radiation doses involved, CT should not be used in place of conventional radiography, and should be restricted to critically ill children who may need neurosurgical intervention (21). Iterative reconstruction and all appropriate dose reduction techniques should be used to reduce radiation exposure (22). Non-contrast-enhanced CT is the imaging modality
Radiation has always been in everyday life even before Roentgen discovered x-ray. The mountains give off natural radiation, other forms of radiation are coal burning power plants, x-rays from a TV, and an airplane ride. The average dose from background radiation is about 360 mrem every year. There are two types of radiation, nonionizing and ionizing radiation. Examples of nonionizing radiation are microwaves and radio waves broadcasting. Ionizing radiation refers to gamma and x-rays. Ionizing radiation
The discovery of fluoroscopy has revolutionised the means physicians view the functions within the body of the patient in order to diagnose and treat (Martin & Harbison, 2006). Although there are many instances where fluoroscopy can be used to benefit patients by providing them with accurate diagnoses, each procedure has risks involved. Fluoroscopic injuries became apparent abruptly after the discovery of x-rays by Roentgen. With time physicians and researchers learned how to efficiently design
In a recent patient review study, one patient answered, “Are the doctors communicating amongst themselves here? It would be so much better for the patient if they were collaborating as a team.” This statement goes for every health care professional in this hospital. Employee actions are not going unnoticed by patients. It’s essential for doctors to have a general understanding of radiology procedures in order to treat patients appropriately. Mandatory training for physician assistants on understanding
New Technology The technology that I have selected to discuss is handheld radiological monitoring. There are several new equipment models being marketed. One of the most recognizable and well-respected names in radiological monitoring is Canberra. One of Canberra’s latest offerings for handheld devices is the Radiagem™ 4000. The device provides the capability of monitoring dose rates and contamination levels. There are a variety of probes available for use with the meter itself. The unit is waterproof
What is radiation? Radiation is energy that comes from a source and travels in the form of waves or high speed particles. Radiation is mainly released from atoms, which is the smallest particle of matter. When radiation is emitted, it excites the orbiting electrons in atoms and causes the electrons to vibrate, which emits the energy. There are two types of radiation, namely Ionizing radiation and non-ionizing radiation. Non- ionizing radiation has a low energy level and therefore cannot change

An Associate's of Applied Science with a focus in Radiologic Technology is a total of seventy four credit hours, which is a total of seven semesters. Depending
sub-specialties include breast imaging, cardiovascular, Computed Tomography (CT), diagnostic radiology, emergency, gastrointestinal, genitourinary, Magnetic Resonance Imaging (MRI), musculoskeletal, neuroradiology, nuclear medicine, pediatric radiology, radiobiology, and Ultrasound (Schenter). After spending a vast amount of time on research and going to internship at the hospital, I have come to realize that my passion in science has greatly intensified. Furthermore, both experiences helped to shape up my
Such medical experimentations on monkeys created severe health problems and infected wounds, bones sticking, chewed-off fingers and toes as well as even resulted to death. For instance, at the Armed Forces Radiobiology Institute in Bethesda, Maryland, “monkeys were forced and even given electric shocks to run on a treadmill” (Owen 45). Such harsh and unethical human actions and abuse of monkeys for humans’ life betterment are unjustifiable as Regan states "fundamental
Animal Rights and Animal Testing Many humans use animals for testing each year. Animal testing is when the animals are put through something or injected to see how they react to what medical research they have been used for. Animals are used to find cures for diseases or to test drugs that have mild side effects. They are also used to test materials for cosmetic research. Except for severely limited medical research, animal testing should be outlawed. Animal testing endangers the animal’s lives

My whole childhood, my family has met at my great-grandparents for holidays. In my great-grandparents yard, they have huge trees that all of the grand kids get in trouble for climbing. Easter of 2003, my cousins and I were doing just what we had been told not to do numerous times and snuck into the biggest tree in the yard. Just as well all got up there and thought we had accomplished not getting caught in that tree, as one of us looks up, a snake is looking at us. Everyone jumped down as fast as
It was April 2nd, 2025, a Saturday in the beginning of summer when a teen, named Josh Arch was home on his dad’s farm in southern Texas working on an old 1972 Chevelle SS. Josh is 16, he has dark blonde hair and brown eyes. Josh was a mechanic for his dad’s business. Josh has a family of four, Josh’s dad and mom and little sister and himself. They lived next to a gas station about a mile from town, which has a population of around 4,000 people. Josh’s family has been around in the town ever since
