MONORING®: Comfort, hygiene and reliability in a single ring dosimeter
MONORING is a ring dosimeter providing you with optimum wearing comfort.
Made of shape memory polyethylene, it fits perfectly to the shape of your finger:
- thin and lightweight so as not to interfere in your activities
- with rounded edges enabling the use of gloves without the risk of tearing them
- rugged to withstand daily wear
The only one-piece ring dosimeter on the market
To ensure easy cleaning and disinfection, the ring is one-piece, with no corner or gap.

Ergonomy
Reliable
MONORING includes a TLD badge made of lithium fluoride.
The badge is placed in a cavity sealed ultrasonically with a lens. This process ensures a secure fit throughout the wear period.
The information engraved on the lens are revealed by laser, making it permanent.

Technical performance
MONORING is the only dosimetric ring on the market certified by the French Accreditation Committee (COFRAC) according to ISO 17025. It is used to measure Hp(0.07) photon and beta doses to extremities from 0.1 mSv. Moreover, its high measuring dynamic and extreme accuracy allow dose measurement up to 10 Sv with a standard deviation greater than 7%.
Its performance has been assessed and validated by the Laboratoire National Henri Becquerel (LNHB), an independent and accredited laboratory.
Physical characteristics
MONORING complies with standard EN 62387:2016 Radiation protection instrumentation – Passive Integrating Dosimetry Systems For Environmental And Personal Monitoring of photon and beta radiation.
