  • Ring dosimeters contain a Lithium Fluoride Thermoluminescent dosimeter (LiF TLD).
  • They are worn on your dominant hand at a point where you believe the greatest potential for exposure will occur.
  • Whole body dosimeters are worn on the collar to measure whole body exposure as well as exposure to the skin and lens of the eyes.
  • Data gathered at the UW data for over 20 years indicates that even when 10 mCi or greater is used, very little personal exposure occurs (less than 10 mrem lifetime dose for most researchers).
