Ring dosimetry monitoring is essential for personnel who work close to radiation sources where hand or extremity exposure may exceed whole-body dose. ProxDose™ offers both OSL and TLD ring dosimeters to support clinical, nuclear, and research environments. Ring dosimeters are designed for comfort, durability, and reliable extremity dose documentation.
The ORA™ OSL Ring uses tissue-equivalent OSL technology to deliver precise extremity dose measurement with excellent stability. Its compact design supports daily wear without interfering with clinical or technical tasks.
Key Advantages
Common Use Cases
TLD ring dosimeters provide durable, regulation-familiar extremity monitoring using thermoluminescent technology. They are well suited for environments where ruggedness and long-standing regulatory acceptance are priorities.

Ring dosimeters are required or recommended when extremity exposure (hands or arms) may exceed whole-body dose, such as in nuclear medicine, interventional procedures, or research environments.
OSL rings offer re-read capability and excellent sensitivity, while TLD rings provide ruggedness and long-standing regulatory familiarity. Both provide accurate extremity dose measurement.
Ring dosimeters are typically worn on the dominant hand, with the sensitive element facing the radiation source. Placement guidance is provided with each program.
Yes. Both OSL and TLD ring dosimeters are designed to be lightweight, low-profile, and comfortable for extended wear.
Yes. Depending on the application, ring dosimeters may be used to monitor exposure to the forearm or lower extremities when appropriate.
Ring dosimeters are reported separately from whole-body badges to clearly document extremity dose.
