Radioactive decay can be described by the following equation In A = In Ao – kt where Ao is the original amount of the substance, A is the amount of the substance remaining after time t, and k is a constant that is characteristic of the substance. -1 For the radioactive isotope lead-210, k is 3.30 x 10 years If the original amount of lead-210 in a sample is 60.0 mg, how much lead-210 remains after 24.6 years have passed? mg
This experiment will use a technique known as neutron activation analysis (NAA) to determine the half-lives of two unusual isotopes, 28 Al and 20F. The only stable isotopes of these elements are 27 Al and 19F. Trace amounts of 26 Al and 18F occur naturally, but the isotopes we will generate today are even more unstable and have no significant natural abundance. To produce these very unstable isotopes in measurable concentration, samples containing Al and F are placed next to a source of energetic neutrons. A number of neutron sources can be used; in this lab the samples are placed inside an operating nuclear reactor that emits energetic neutrons. This source has the advantage of a high neutron output that creates the desired isotopes rapidly and at higher concentrations, but it is only feasible for researchers that have access to nuclear reactors. At Oregon State University, the campus TRIGA reactor is set up for NAA experiments. SECTION 2 Based on the description from the last…
