Ionizing radiation

electrons. An ion is formed when an atom loses or gains a electrons . Radioactivity is when energy is emitted from the nucleus due to the nucleus being unstable. The 3 types of radiation are Alpha ,Beta and gamma. Alpha particles have 2 protons and two neutrons. Examples of radioactive nuclei that emit alpha radiation. Are : uranium, thorium, actinium, and radium They are very ionising so they give energy off onto whatever they are in contact with. Therefore, it loses energy more quickly. They

Introduction Understanding the effects of radiation in utero is an important area of research. Expectant mothers may require examinations involving exposure to radiation to diagnose or treat a medical condition (Nguyen & Goodman, 2012). Radiologists are exposed to radiation each day at work, which is particularly concerning when health professionals become pregnant. In utero development involves massive proliferation and organization of new cells. Ionizing radiation pulls electrons away from atoms and

Introduction Power lines are cables that carry electrical power (Google definitions 2015). This electrical power is generated by Eskom, an electrical energy supplier company, and carried via the power lines to many areas around the country. To be able to produce so much current to the whole of country, AC generators are normally used (Horner, Davies & Toerien 2012). A generator is a device that turns mechanical energy into electrical energy (Olivier 2015). A generator is usually either

pros and cons to each. This paper will discuss MRI, CT, and ultrasound. They each have important things to know regarding radiation dose, cost, and reasons to use one over another. MRI provides both anatomic and physiologic information. It is the modality of choice when cartilage, nerves, or organs are of interest. Magnetic resonance imaging does not give off any ionizing radiation. Instead, the magnetic force reacts with the hydrogen in our bodies to show the images. Because of this fact, it is the

Food and food products purchased in supermarkets around the world are known to have chemicals to kill bacteria, improve food safety, and increase shelf life. According to an article on Waking Times, meat and poultry purchased in markets are known to have at least 10 chemical additives including Sodium Benzoate, Sodium Proprionate, Benzoic Acid, Nitrites and nitrates, as well as traces of antibiotics that were given to the animals (Longo). However there is another way to fight off bacteria and harmful

Beginning with the accident at Three Mile Island in 1979, a widespread belief has proliferated that all levels of ionizing radiation are dangerous. Since 1980, radiation hormesis studies have shown there is actually a threshold of danger with high level exposures, but below that threshold low dose radiation is essentially safe and quite possibly beneficial to life. Yet, this relatively new, seemingly contradictory understanding of radiation's health effects has gone essentially unknown to the general

X-rays are a form of electromagnetic radiation similar to visible light. However, unlike visible light x-rays can pass through most objects, including the body (NIBIB, n.d). The radiation hits a detector on the other side of the patient and the image produced is a shadowed representation of the tissues and structures in the body (NIBIB, n.d). However, due to the type of radiation being superimposed over the body it is worrying knowing that this form of radiation can, in some cases, cause some very

(Kleinsmith, Lewis J. M.D). Some cancers may be cured and this depends on certain variables such as the type of cancer, where the cancer is, and how early it has been detected. One method of treatment for cancer is Radiation therapy (Radiotherapy). This is the medical use of ionizing radiation to control or kill these malignant cells. However, there is doubt among society about the use of radiotherapy. This is mainly because some long-term side effects include the growth of scar

Bomb Radiation Radiation from nuclear bombs releases radiation that is very harmful and has many weird effects to people and the environment. Radiation is defined as the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization. Beside shock, blast, and heat a nuclear bomb generates this high intensity radiation. This radiation has basically two different kinds, electromagnetic and particulate, and is emitted not only at

The key principle behind radiocarbon-14 dating is plants and animals exchange carbon with their surroundings and thus contain the same ratio of carbon-12 to carbon-14 once an organism dies it no longer exchanges carbon with its surroundings. The carbon-14 will slowly decay at a known rate decreasing the ratio of carbon-12 to carbon-14. Since the decay rate and original ratio of carbon-12 to carbon-14 is known we can determine how old a sample is by the amount of carbon-14 remaining. There are two
