Ionizing radiation

Food irradiation is the exposure of a carefully measured amount of ionizing radiation to food. This is done in a processing room or a sealed chamber for a specified amount of time. With food irradiation, energy from radiation breaks chemical bonds, leaving the food fresh and nutritious, but with specific benefits, depending on the treatment type. (1) Food irradiation kills bacteria in the food and interferes with its molecular bonds to stop it from multiplying. (2) There are three ways that food

Exposure to ionizing radiation is of concern to many medical practitioners. The risks of radiation exposure are well documented within the scientific literature and include cataract formation, skin cancer, thyroid disease and leukaemia.1 Medical staff who work in the operating theatre are a sizable population potentially at risk for these complications.2 With advances in medical technology in past decades and an ongoing trend towards minimally invasive techniques, there has been a significant increase

I have found that radiation can either be very helpful or very dangerous, this all depends on the amount and how it's used.The definition of radiation is the process by which energy is emitted as either particles or waves(mirion 2010).Radiation is measured in waves or curies. Curies is named after one of the radiation founders Marie Curie. Radiation was discovered by many different people. Radiation is used in many helpful ways such as medical and home use. It can also used to kill bacteria and parasites

innovations; however, progress of the past is, systematically, detrimental to the future. Not long after the revolutionary invention of the X-ray in the late 19th Century, an unprecedented number of medical examiners noticed (unknown to the time) radiation burns all over their body; decades later, an extraordinary surge in cancer cases had arisen. Perhaps, during the course of these years, scientists and researchers desired to further progress the x-ray (into the immense subsidiaries that are here

Introduction It is difficult to determine the birth of nuclear medicine due to the many contributions made my scientists of carious fields. However, most notably, during bla blah Understanding the uses, benefits and side effect of nuclear medicine is crucial due to its significant and ongoing contribution to the medical field. Throughout this paper focus will be placed on how radioactivity has benefited the detection, control and at times, complete elimination of cancer. Background Nuclear medicine

Introductions Beta Radiation is a high-energy electron that carries a negative charge. That is send out by some radioactive nuclei. And it is ionizing than Alpha radiation and more ionizing than gamma rays. This makes travel through many centimeters or even meters. And millimeters through the skin and tissue. Effects on living things The Washington State Department of Health takes note of that beta particle exposure can have deferred wellbeing impacts on the body. Any quantity of radiation exposure may

Cancer has become an epidemic across America. About 13 million Americans have cancer and a little over 1 million are diagnosed every year. For years Oncologist have been looking for treatments to cure this horrible disease(American Cancer Society, 2013). Chemistry has such a major impact on the research of cancer. The chemistry within Oncology & Cancer Research has greatly increased our knowledge and capabilities for developing new treatments or actually finding a significant cure (American Cancer

of the 20th century, and speculation about its future commercial prospects. Researchers in the United States and Great Britain filed patents in 1905 for using ionizing radiation to kill food-borne bacteria (Spiller, J. (2004)). Therefore, food irradiation has over 100 years of history. Food irradiation (the application of ionizing radiation to food) is a technology that improves the safety and extends the shelf life of foods by reducing or eliminating microorganisms and insects (“U.S. Food and Drug

determine the effect of different amounts of gamma rays radiation on the growth of corn (Zea mays) and to observe the damage it has brought in relation to the amount used for the treatment. The specific objectives were: 1. To observe the changes in the plant growth and the effect of each treatment to the plants in terms of % germination and survival rate. 2. To explain why the plants has acted such towards different doses of radiation. 3. And to describe which amount is helpful and optimum

just structure. The result is that many diseases and cancers can be diagnosed much earlier. Nuclear medicine procedures utilize very small doses of short-lived isotopes (ones that only stay radioactive for a few hours or days), the amount of radiation received is generally less than or equal to that of an x-ray. Whole body and healthy tissue doses can be minimized while the radioisotope is targeted toward the affected tissue or organ. The isotope is then eliminated by the body through the urine
