Introduction (5:03) 1. What is the name for all the electromagnetic waves that exist? Names of the electromagnetic waves that exist are Gamma Rays‚ X-Rays‚ Ultraviolet Waves‚ Visible Light‚ Microwaves‚ and Radio Waves. 2. What are electromagnetic waves produced from? What two things do they have? Electromagnetic waves are produced by the vibration of charged particles and have electrical and magnetic properties. 3. What is the name for the section of the electromagnetic spectrum that

Transuranic Elements and their Production Transuranic elements are elements that have an atomic number greater than 92. Transuranic elements have been synthesised in nuclear reactors or in high-energy particle accelerators. Neptunium and plutonium were the first transuranic elements to be synthesised in 1940 by Glenn Seaborg’s research team in the USA. Uranium 238 is bombarded with neutrons produced by the nuclear fission of U-235. Initially an isotope of uranium (U-239) forms which decays

about different variations of treatments‚ those in which have helped millions combat diseases. It uses radiation to administer information about the functioning of a person’s organs or to treat diseases. It detects early signs in the tissue. Nuclear medicine procedures are very safe and do not require anesthesia. A small dose of radiopharmaceuticals is introduced into the body with low radiation and still provide a definite medical evaluation. That is why it has been around for so long. It is important

radiant energy and a way to confine the energy. (1) The source for gamma radiation can either be the radioactive form of the element cobalt‚ which would be Cobalt 60‚ and the element cesium‚ and that would be Cesium 137. These substances do not give off neutron which means that they don’t make anything around them radioactive. When not in use‚ this source is kept in a pool of water which completely absorbs the radiation. To irradiate the food‚ the source is pulled from the pool and into a chamber

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

Radioactive Isotopes Radioactive isotopes are any of several species of the same chemical element with different masses whose nuclei are unstable and dissipate excess energy by spontaneously emitting radiation in the form of alpha‚ beta‚ and gamma rays. Every chemical element has one or more radioactive isotopes. More than 1‚000 radioactive isotopes of the various elements are known.. Approximately 50 of the isotopes are found in nature; the rest are produced artificially as the direct products

spread out from the focal spot‚ through the tube window and onto the region to be examined. How is an image formed? X-ray films that are used in dental radiography consist on an emulsion/gelatine mix containing chemicals that are sensitive to x-ray radiation. This is a silver halide - either bromide or chloride. The emulsion/gelatine mix and their suspension is set onto a flexible‚ transparent tinted blue base. Emulsion is used in all types of analogue photography‚ but the type used in x-ray photography

of imaging‚ the number of adverse events has only increased in clinical settings across the past decade. MRI is considered the safest imaging modality because it can produce the most information from a patient while not delivering any ionizing radiation‚ unlike x-rays‚ fluoroscopy‚ etc. New safety screening technologies and safety practices have much promise in reducing these adverse events. MRI is a noninvasive diagnostic technology that can also be used with pregnant women‚ growing children‚ but

few types of weeds and insects but Rachel Carson poses the question “Can anyone believe it is possible to lay down such a barrage of poisons on the surface of the earth without making it unfit for all life?” (614). Carson also touches on man-made radiation releasing harsh chemicals into the air‚ such as Strontium 90‚ which comes down as rain and soaks into the earth or even “…in time takes up its abode in the bones of a human being‚ there to remain until his
