Radioactive Emissions

Radioactive emissions are electromagnetic radiations which occur due to the spontaneous disintegration of unstable nuclei. Natural elements with atomic number greater than 83 and isotopes of some lighter elements are found to be radioactive. They are categorized as alpha, beta and gamma radiations. Alpha particles are positively charged helium-4 nuclei , beta particles are high energy-high speed electrons while gamma rays unlike alpha and beta radiation have no mass and charge and are short electromagnetic waves consisting of high energy photons. While alpha and beta radiations have low and moderate risk of damage, gamma rays can cause severe damage to internal organs and even death on skin exposure. A brief description of various types of radioactive emissions is given below…

Ionising radiation in medical imaging

Contemporary medical practice is heavily reliant on mediconuclear and radiological procedures and investigations. To derive important diagnostic information, medical personnel must carry out investigations which may expose patients and the medical personnel to certain levels of risk. With the continued advancement of medicine and diagnostic examinations, many procedures which utilize relatively high loads of radiation to produce images are becoming more and more popular. To protect patients and radiologists from the harmful effects of radiation exposure, protection practices and standards are grounded on the understanding that any level of radiation may cause detrimental health effects, including genetic damage and cancer development. However, while protection standards have been crucial in reducing the level of exposure to harmful radiation, these estimates are…

Harmful Effects of Television

Television is a medium of communication, information, and entertainment. It is the most popular system for transmitting images and sounds to people. In fact, television can have negative effects due to radioactivity, falsehood and obsession. First of all, television releases radiation. A lot of people believe that television is harmless. However, scientific studies prove that unlike any other household equipment television sends out a lot of radioactive rays. Indeed, radiation deteriorates vision. As well, it can damage it. For example, some people like to sit close to TV sets. Their eyes are too close to the screen and radioactive rays are constantly getting in their eyes. For that reason, television harms people’s vision. Television sends out radiation that has negative…

Radiology. Lonizing radiation

I. Introduction A.(Opening Device) I’m sure most of you in here have broken, fractured, or sprained something in your body before. And you had to take that dreadful trip to the ER after whatever crazy and or stupid thing you just did. Or it might even just been from you playing the sport you love. My favorite part of that trip is when they finally bring in the x-rays and you get to see the part of your body that should not look like it does in the picture. I’d love to share how some of the equipment they use to see these things work! B.(Thesis Statement) When I grow up, I want to be a radiologist. C.(Preview of Main…

Li-Fi Technology

I. Introduction Li-Fi or Light Fidelity is a technology that uses light emitting diodes to transmit data wirelessly. It was first demonstrated at a TED talk in 2011 by German physicist Harald Haas. This is a free band that does not need any license. Hence it is cheaper than Wi-FI. Wi-Fi, is a popular technology that allows an electronic device to exchange data or connect to the internet wirelessly using radio waves the visible light spectrum is larger than the radio spectrum which provides better flexibility in its use. Communications over a very high speed with a theoretical limit of 10 GB per second. The technology is capable of transferring thousands of streams of data simultaneously, in parallel, at higher speeds,…

Radioactivity

People consider me as a caring, patient, friendly, and responsible person. I am very energetic; whenever I start working on something I never want to give up. I have a passion for becoming a nurse since I enjoy helping people around me. I get along with others very well, which make me always being cooperative with my co-workers and work with them toward a share goal. I graduated from Highline Community College last year with honor degree. Even though I already obtained my AA degree in Pre-Nursing, gaining my knowledge in the medical field is not enough for me. I want to gain more clinical patient experience and help people with all my heart. In order to strengthen my clinical…
