Who needs a radiation dose monitor (film badge)?

If it is likely that your radiation dose will exceed 10 percent of the U.S. Nuclear Regulatory Commission’s limits or 25 percent of the State of CT Department of Energy & Environmental Protection limits, you will need to wear a personal radiation monitoring badge.

All users of medical x-ray equipment (C-arms, fluoro units, therapy units) must wear badges. Those using larger quantities of radioactive materials will also be provided badges. Those using 10 millicuries or more of P-32 or other high-energy beta (or gamma) emitters will also be provided ring badges to monitor their hand exposures. Those using only H-3, C-14 and S-35 will not be provided badges as radiation from these low-energy beta emitters cannot be recorded on the badge monitor.
