thermoluminescent dosimeter

(thĕr″mō-loo-mĭ-nĕs′ĕnt)
A monitoring device consisting of a small crystal in a container that can be attached to a patient or to a health care worker. It stores energy when struck by ionizing radiation. When heated, it will emit light proportional to the amount of radiation to which it has been exposed.

Thermoluminescent dosimeters (TLDs) were positioned on the breast phantom surface at the 12 o'clock, 3 o'clock, and 6 o'clock positions; at the nipple level equivalent; and underneath the breast phantom on the chest wall.
Uncertainties in dose estimates in the worker cohorts are caused by sampling variation in measurements from film badges and thermoluminescent dosimeters, adjustments made to doses below the limit of detection, and attenuation of externally measured dose by shielding (Gilbert 1998; Gilbert and Fix 1995).
Landauer expects these new technologies will combine the best features of current methods for monitoring personnel radiation exposure, namely photographic film and thermoluminescent dosimeters (TLD), as well as offer a number of distinct advantages.
