A radioactive tracer, radiotracer, or radioactive label, is a chemical compound in which one or more atoms have been replaced by a radionuclide so by virtue of its radioactive decay it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products.
Moreover, what does un2911 mean?
Excepted packagings are authorized for limited quantities of radioactive material that would pose a very low hazard if released in an accident. (Note: 2910 means Radioactive material, excepted package-limited quantity of material.)
One may also ask, what is the transport index of a radioactive material? The transport index (TI) is derived from the maximum dose equivalent rate at one meter from the surface of a package containing radioactive material.
Accordingly, which radioactive label is for packages with high radiation levels?
RADIOACTIVE WHITE-I is the lowest category and RADIOACTIVE YELLOW-III is the highest. For example, a package with a transport index of 0.8 and a maximum surface radiation level of 0.6 millisievert (60 millirems) per hour must bear a RADIOACTIVE YELLOW-III label.
Which label is used for packages with low radiation levels?
The Radioactive White-I label is attached to packages with extremely low levels of external radiation. The maximum contact radiation level associated with this label is 0.5 mrem/hour.

Excepted packages may only contain limited quantities of radioactive material, which are so small that the potential radiological hazards that might pertain during transport are very low.How does radiation contaminate?
Contamination occurs when material that contains radioactive atoms is deposited on materials, skin, clothing, or any place where it is not desired. It is important to remember that radiation does not spread or get "on" or "in" people; rather, it is radioactive contamination that can be spread.What is radioactive LSA?
