CALIBRATION OF THERMOLUMINESCENCE AND FILM DOSEMETERS FOR SKIN DOSES FROM HIGH-ACTIVITY MICROPARTICLES.

The use of EXT-RAD (TM) extremity TLDs and radiochromic film to measure doses from primarily beta-emitting microparticles is discussed. Specific calibration techniques have been developed, using both Monte Carlo modelling and experiments. Results for a Sr-90/Y-90 microparticle are presented to illustrate the general techniques and to demonstrate reasonable agreement between the dosimetry methods.
