Up to 300 samples are placed in sealed vials or test tubes, and move along a serpentine track on a horizontal plane. One at a time, they move down inside a shielded detector, set to measure specific energy windows characteristic of the particular isotope. Depending on the half life and concentration of the sample, measurement times vary from 0.02 minute to one minute.

About the term s use in physics File What are Gamma rays.ogv thumb 300px What are Gamma rays? File Gamma Decay.svg 240px thumb Illustration of an emission of a gamma ray &gamma from an atomic nucleus Gamma radiation , also known as gamma rays or hyphenated as gamma rays and denoted as gamma &gamma , is electromagnetic radiation of high frequency and therefore energy. Gamma rays are ionizing radiation and are thus biologically hazardous. Gamma rays are classically produced by the decay from high energy states of atom ic nuclei gamma decay , but also in many other ways. Natural sources of gamma rays on Earth include gamma decay from naturally occurring radioisotope s such as potassium 40 , and also ... rare terrestrial natural sources that produce gamma rays that are not of a nuclear origin, are lightning strike s and terrestrial gamma ray flash es, which produce high energy emissions from natural high energy voltages. Gamma rays are produced by a number of astronomical processes in which very high energy electrons are produced. Such electrons produce secondary gamma rays by the mechanisms of bremsstrahlung ... gamma rays are screened by Earth s atmosphere and must be detected by spacecraft. Notable artificial sources of gamma rays include Nuclear fission fission such as occurs in nuclear reactors, and high energy physics experiments, such as pion neutral pion decay and nuclear fusion . The first gamma ray source to be discovered historically was the radioactive decay process called gamma decay. In this type of decay, an excited nucleus emits a gamma ray almost immediately upon formation. Isomeric transition , however, can produce inhibited gamma decay with a measurable and much longer half life. Paul Villard , a French chemist and physicist, discovered gamma radiation in 1900, while studying ... s radiation was named gamma rays by Ernest Rutherford in 1903. ref Rutherford named rays on page ... , Series 6, vol. 5, no. 26, pages 177 187. ref Gamma rays were named in order of their penetrating ... more details
