Earn your Bachelors of Science in Nursing (BSN) while you workâno matter where you live. All eight of the Indiana University School of Nursing campuses across the state of Indiana joined to create the RN to BSN Degree Completion Option. This means that nursing courses are distance accessible, using Web-based and video technologies rather than requiring you to come to campus.
Radioactive materials used in medicine: radionuclides and radioactive isotopes. A radionuclide is any type of radioactive material, including elements and the isotopes of elements. An isotope of an element is a particular atomic version of it. Isotopes are atoms of the same element with different atomic structures.
Definition. Radioactivity in minerals are caused by the inclusion of naturally-occurring radioactive elements in the mineral's composition. The degree of radioactivity is dependent on the concentration and isotope present in the mineral.For the most part, minerals that contain potassium (K), uranium (U), and thorium (Th) are radioactive. This table lists all of the naturally-occurring radioactive isotopes.Mineral radioactivity is due to alpha, beta, and gamma radiation from the unstable isotopes in the composition.efinition.
