Radioactive label on containers aboard a US Navy ship. Any quantity of packages bearing the RADIOACTIVE YELLOW III label (LSA-III). Some radioactive materials in "exclusive use" with low specific activity radioactive materials will not bear the label, however, the RADIOACTIVE placard is required.
Division 1.3: Substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard Note : The asterisks are replaced by the class number and compatibility code
Lutetium tantalate (LuTaO 4) is the densest known stable white material (density 9.81 g/cm 3) [51] and therefore is an ideal host for X-ray phosphors. [52] [53] The only denser white material is thorium dioxide, with density of 10 g/cm 3, but the thorium it contains is radioactive.
A chemical hazard symbol is a pictogram applied to containers and storage areas of dangerous chemical compounds to indicate the specific hazard, and thus the required precautions. There are several systems of labels, depending on the purpose, such as on the container for transportation, containers for end-use, or on a vehicle during transportation.
The reactant is 'labeled' by replacing specific atoms by their isotope. Replacing an atom with its own radioisotope is an intrinsic label that does not alter the structure of the molecule. Alternatively, molecules can be radiolabeled by chemical reactions that introduce an atom, moiety, or functional group that contains a radionuclide.

Salmonella bacteria cause about 1.3 million infections, 26,500 hospitalizations and 420 deaths in the U.S. every year, with food being the source for most of the illnesses, according to the ...
A chart or table of nuclides maps the nuclear, or radioactive, behavior of nuclides, as it distinguishes the isotopes of an element.It contrasts with a periodic table, which only maps their chemical behavior, since isotopes (nuclides that are variants of the same element) do not differ chemically to any significant degree, with the exception of hydrogen.
