What is the radiation exposure limit at 1 meter from a Yellow III package?

The radiation exposure limit at 1 meter from a Yellow III package is indeed set at 200 mR/hr. Yellow III packages are classified under the Department of Transportation's (DOT) transportation classification system for radioactive materials. This classification is important because it helps define the safety standards and radiation limits that must be adhered to during the transportation of radioactive materials.

The 200 mR/hr limit at 1 meter from the package is established to ensure safety while allowing for the practical transport of radioactive substances. The classification indicates that while the package can emit radiation, it is designed to protect handlers and the general public by maintaining a level that is considered acceptable for transport under controlled conditions.

In terms of safety protocols, these limits take into account the expected distance of personnel from the source, ensuring that exposure remains below levels that could pose health risks in the short term.
