Chapter 1 Introduction According to Bushong (2009)‚ radiation is an energy that moves through space or matter at a very high speed. This energy can be in the form of particles‚ such as alpha or beta particles‚ which are emitted from radioactive materials‚ or waves such as light‚ heat‚ radiowaves‚ microwaves‚ x-rays and gamma rays. He also mentioned that radioactive materials which is also known as radionuclides or radioisotopes are atoms that are unstable. So‚ there is a tendency for unstable atoms

simulations show that a combined use of textiles with the right properties as a shield provides great possibilities for reduction of the RF effects over the human body. This can be proved from the results obtained at probe 1 which estimate the amount of RF radiation below the skin layer‚ are showing that the average SAR level with all kinds of shielding materials is ≥ 400 % lower than in the case without shielding (in the case with both shielding materials the reduction is > 300 times in the strength of the

Sterilization The radioisotope therapy has been available to those disease conditions in which extensive cellular malfunction exists. Diagnostic radiopharmaceuticals are used to derive detailed description of the morphology and dynamic functioning of the various internal organs of the body. The radiopharmaceutical accumulated in an organ of interest emit gamma radiation which are used for imaging of the organs

element‚ however‚ unlike elements‚ they feature a differing mass number‚ meaning the amount of protons and neutrons is imbalanced. (Gothard‚ 2004) Sometimes‚ an isotope exists with an unstable nucleus‚ spontaneously emitting excess energy through radiation known as alpha (α) particles‚ beta (β) particles or gamma (?) rays.

15% in Ukraine and Russia and the other 15% dispersed over the rest of the world. Most of Europe receives additional radiation and even as far as North America‚ a significant rise in the daily intake of radiation can be noted. A 30% increase in child mortality was registered in May and June of 1986 in New Jersey‚ while southern Germany measured a 70% rise. 3 80-90% of the radiation dose received by the inhabitants of the affected areas was and is internal‚ due to the oral intake of contaminated

We went there to job shadow the nurses that work in our department. While job shadowing our goal is to follow the nurses and observe them giving basic care to patients. Upon arriving at Grand View Hospital I was feeling nervous with the thought of going to Radiation Oncology. I was nervous because I have

Food poisoning is an illness caused by eating contaminated food. Food poisoning is a term given to infections with bacteria‚ viruses‚ or toxins from germs that affects humans via contaminated food or water. Today I would to talk about causes‚ symptom‚ and treatment of food poisoning. Food Poisoning caused by a lot of problem. That is clean‚ check‚ separate‚ cook‚ chill‚ throw away. First is clean.

Alcohol Poisoning Not many people know about or what alcohol poisoning is. You can get it from excessive drink which will result in not only harming yourself‚ but others around you too. Some people find that drinking is a joke or think it’s funny‚ but it’s not. Every time you drink alcohol‚ your liver has to filter out the poisonous alcohol from your blood. Alcohol is absorbed quickly into your body (much quicker than food)‚ but the body can only process around one unit of alcohol each hour. If
