Question by player Booklover17

Answer: Move closer to the source

ALARA -- "As Low As Reasonably Achievable" -- is the bedrock principle for working around radiation. The radiation from a source falls off as one over the distance squared, so if you're a meter away, you'll get only 1/100 of the dose you would have received at 10 cm. You also want to spend as little time as possible near the source; it's a very good idea to rehearse your actions, so that you'll be able to perform them smoothly and quickly. Finally, you can add shielding between yourself and the source, like the lead apron that's used when you get dental X-rays.

The best kind of shielding will depend on the type of radiation that you expect, but there's always something that will help.
