Ring Dosimeters

Superior Responsiveness and Construction

Perfect for those who handle radioisotopes or who perform interventional radiographic procedures, GDS ring dosimeters provide accurate readings of the radiation you are receiving. By regularly reviewing Exposure Reports you'll be able to monitor radiation levels and limit the amount of exposure to your hands.

GDS offers a choice of three sturdily constructed ring dosimeters.

  1. MeasuRing™

    The MeasuRing consists of one natural lithium fluoride TLD element and offers immersible, bar-coded single-piece construction so you can work with it anywhere, even in wet environments.

  2. LiF 1 chip Flex Ring

    The GDS Hard Ring dosimeter consists of one lithium fluoride element placed in a flexible plastic ring holder with velcro closure straps.

  3. Ultra Ring

    The new Ultra Ring offers a ruggedly strong holder that's more resistant to breaking with a single chip of natural lithuim flouride TLD 100.


For low energy beta, x-ray or gamma radiation monitoring of hands and fingers. (There are fourteen specific source and mixture calibration factors available).
