Radiography nuclear medicine

What types of tests are necessary Taboratory testing, radiography, nuclear medicine, physical therapy, or other services should be contacted about the proper method of sending samples, ordering tests, and paying for services. Some institutions may offer research discounts for tests. 

Soft, silvery metal whose isolation is difficult. Ytterbium fluoride is added to dental fillings (as X-ray contrast agent). Ytterbium is a constituent of rust-free special steels. Yb2Co13Fe3Mn holds the magnetic world record, but is too expensive for commercial purposes. The element is occasionally applied in nuclear medicine and radiography. It also activates phosphors that convert infrared rays into visible light. 

In justifying each type of diagnostic examination by radiography, fluoroscopy or nuclear medicine, relevant guidelines will be taken into account, such as those established by the WHO (1983, 1987, 1990). 

Radioisotopes are used fi>r a wide variety of applications. Cobalt-60, for example, is used to treat cancer and to sterilize medical products. Other radioisotopes are used in nuclear medicine as tracers that can be injected into the human body to help dispose and treat illness. In industrial radiography, radioisotopes allow engineers to inspect the internal integrity of industrial castii and welds. 

Class 7 Radioactive substances and articles (sources In nuclear Industry, Industrial radiography, military, nuclear medicine, radiotherapy)... 

Radioactive heavy elements such as uranium, thorium, or plutonium are used as nuclear fuel radium is used in the radiography of metals and radon is used as a surface label to study surface reactions, as well, in the determination of radium or thorium. Among the lighter isotopes, Ni is used in electron capture detectors for GC analysis, in radiocarbon dating and as a tracer, and tritium in nuclear fusion and as a tracer in the studies of reactions. Many radioactive elements are used as a source of radiation, in medicine to diagnose disease, and for treatment. 

Manmade sources of radiation include industry (mining, food sterilisation, radiography of pipes, luggage and buildings), medicine (imaging, radiotherapy), nuclear power and weaponry. Weak radiation sources are also found in smoke detectors.
