The 1800 Ring TLD Dosimeter is designed for occupational extremity monitoring where the dose to the fingers may be higher than the whole-body badge reading. It is commonly discussed for nuclear medicine, radiopharmacy, interventional radiology, isotope handling and other workflows where hands operate near radiation sources.

Typical applications
- Nuclear medicine departments
- Radiopharmacy and isotope preparation
- Interventional radiology support work
- Research laboratories using radioactive materials
- Industrial or service workflows requiring finger dose monitoring
Product-sheet specifications
- Ring size: Phi 18 x 12 mm
- Detector capacity: 1 TLD detector element
- Detector options: LiF(Mg,Ti), LiF(Mg,Cu,P)
- Color options: red and green
- Wearing position: finger
- Typical use: hand and finger dose monitoring
Detector and reader compatibility
Ring dosimeter enquiries often involve replacement for an existing dosimetry system. The ring holder, detector chip size, detector material and reader workflow should be confirmed before quotation. This is especially important when the customer refers to RADCARD, Harshaw or another existing reader system.
Compatibility note: do not assume a ring dosimeter is compatible only because it uses a common LiF detector material. Confirm the reader model, detector dimensions, ring loading method and readout workflow first.
