Technical specifications

dosimeter for finger extremityWith this design, the TLD is safely encapsulated underneath the ring cap which is ultrasonically welded to the polyethylene ring base. Under  even the harshest working conditions, it’s difficult to remove the ring cap from the ring base, so the chain of custody between the chip and the wearer is always maintained.

The identification on the cap is laser engraved, preventing the print from smearing, peeling, or washing off. Rings can be worn in dry or wet working conditions. Smooth edges allow rings to slide and fit inside surgical gloves without risk of tearing. The dosemeter is to be worn with the sensor towards the irradiation source
