Which of the following does NOT need to be double-bagged?

A surplus source that is not leaking.
A leaking radioactive source.
A damaged radioactive source.
A source with unknown leakage.

The correct answer is: A surplus source that is not leaking.

The situation involving the surplus source that is not leaking is the only one that does not necessitate double-bagging. In radiation safety practices, double-bagging is a protective measure to contain potential leaks and ensure that any hazardous materials do not escape into the environment. When handling a leaking radioactive source, a damaged radioactive source, or a source with unknown leakage, double-bagging is crucial. These circumstances present a risk of exposure or contamination, and double containment provides an additional layer of safety. The first choice, however, pertains to a surplus source that is stable and not leaking, which does not pose an immediate risk of radioactive material escaping. Thus, single containment is sufficient in this case, highlighting the importance of assessing the condition of the radioactive source to determine the appropriate safety measures.
