Final answer:
LSA stands for Low Specific Activity, which refers to radioactive materials that have a low radioactivity level in relation to their mass, important for safe handling and transportation.
Step-by-step explanation:
The acronym LSA in the context of packaging RAM for shipment stands for Low Specific Activity. Option B is the correct answer. Low Specific Activity refers to a classification for radioactive materials which have a low level of radioactivity in comparison to their mass.
This term is used specifically in the nuclear materials industry and plays an important role in the safety protocols for handling, packaging, and transporting these materials, ensuring that they are done so in a manner that minimizes exposure and risk to people and the environment.
