Experience of type testing Harshaw advanced TLD system to new IEC-61066 standard

Abstract

The recently released IEC 61066:2006 standard [IEC 61066:2006. International Standard, Thermoluminescence Dosimetry Systems for Personal and Environmental Monitoring] is a new guideline for type testing a TLD dosimetry system. A few main changes made in this standard include harmonizing the reference radiation and calibration with ISO standards, integrating the basic uncertainty analysis, and aligning IEC uncertainty requirements on dosimetry systems with those stated in ICRP Publication 75. We tested to this standard with an advanced Harshaw TLD system: Model 8800 Plus Reader and LiF:Mg,Cu,P dosemeter. This work describes the more than 10 tests in four major categories and provides the learning experience in uncertainty analysis.
