In medicine, gamma rays emitted by radioactive elements are used to detect tumors inside the human body. Isotopes and Their Uses The discovery of isotopes is best understood in the context of the spectacular advances in physics and chemistry that transpired during the last 200 years. and eliminate those with powerful gamma rays emissions, only about 30 isotopes are left. Sheets of metal used in construction must be the same thickness all the way through. Messing with the Mass If you have looked at a periodic table, you may have noticed that the atomic mass of an element is rarely an even number. This topic is school chemistry (or high school chemistry in the USA) up to 14-16 yrs, GCSE in UK. isotopes are separated from each other by passing a gas containing them through a strong magnetic field, which deflects them differentially according to their mass. Please visit their site for more information. But in pure form, it is highly inflammable. air for N, At%15N = 0. 2 Many elements also have radioactive (non-stable) isotopes. Battaglin, and Donald H.
