Dosimeters

back arrow       forward arrow

Dosimeters are used to measure the radiation dose to an individual. Dosimeters do not provide any protection from radiation. The dosimeter should be clipped to the clothing between the waist and neck. The collar is the recommended location of the dosimeter because it is typically the maximally exposed area of the body.

Luxel dosimeters:

Luxel dosimeters utilize inorganic crystals to measure radiation dose. These dosimeters are exchanged monthly or quarterly depending on the potential exposure of the individual. These dosimeters are hexagonal in shape. If a Luxel Dosimeter has been issued to an individual, he/she must always wear it when entering a therapy patient room and the dosimeter may not be worn by anyone else.

Extremity Rings:

Thermoluminescent Chips are placed in rings and are used to monitor exposure to the hands and fingers. Only personnel who may handle radiation sources should have these rings.

The University of Washington Radiation Safety Manual contains additional information on dosimeters.
