Rem

Short for Remington

Rem is a unit measuring radiation absorbed by human tissue, from "roentgen equivalent man." It quantifies biological damage rather than raw energy, making it useful for setting safety limits: The annual exposure limit for radiation workers is five rem.

Largely replaced by the sievert in scientific contexts, but rem persists in U.S. regulations and medical settings.
