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.
Some radioactive elements glow because of their radioactive decays. They emit electrons or alpha particles, changing from one kind of element to another, and as the electrons in the atoms rearrange themselves to the new atom's configuration, they emit light. Radium was used for watch dials because it glows green.horium, a naturally ocurring radioactive element, is used in making mantles for gas and kerosene lamps because thorium oxide glows brightly when heated. The radioactive elements uranium and plutonium are used in the generation of electricity in nuclear power plants.
