91TRIUMF — is Canada’s national laboratory for particle and nuclear physics located on the University of British Columbia campus in Vancouver, British Columbia. The name, formerly abbreviated from TRI University Meson Facility, is now no longer an… …
92Isotopes of niobium — Naturally occurring niobium (Nb), element 41, is composed of one stable isotope (93Nb). 93Nb is the lightest nuclide theoretically susceptible to spontaneous fission, and although this has never been observed, it makes niobium theoretically the… …
93Cadmium — (pronEng|ˈkædmiəm) is a chemical element with the symbol Cd and atomic number 48. A relatively abundant (price 3.55 USD/lb as of 2008 02 15), soft, bluish white, transition metal, cadmium is known to cause cancer and occurs with zinc ores.… …
94Isotopes of cadmium — Naturally occurring cadmium (Cd) is composed of 8 isotopes. For two of them, natural radioactivity was observed, and three others are predicted to be radioactive but their decays were never observed, due to extremely long half life times. The two …

96Technetium-99 — (99Tc) is an isotope of technetium which decays with a half life of 211,000 years, emitting soft beta rays but no gamma rays, and has a fission product yield of 6.0507% for thermal neutron fission of uranium 235. It is the most significant long… …
97Extinction (astronomy) — Extinction is a term used in astronomy to describe the absorption and scattering of electromagnetic radiation by matter (dust and gas) between an emitting astronomical object and the observer. Interstellar extinction also called Galactic… …
98Ruthenium — (pronEng|ruːˈθiːniəm) is a chemical element that has the symbol Ru and atomic number 44. A rare transition metal of the platinum group of the periodic table, ruthenium is found associated with platinum ores and used as a catalyst in some platinum …
99Fission products (by element) — On this page, a discussion of each of the main elements in the fission product mixture from the nuclear fission of an actinide such as uranium or plutonium is set out by element. Krypton 83 86 Krypton 85 is formed by the fission process witha… …
