Influences and their corrections for the new H*(10) TL area dosemeter Seibersdorf

A new area dosimeter for environmental and workplace monitoring based on LiF:Mg,Ti (TLD-100) thermoluminescence detectors was developed at the Austrian Research Centers in Seibersdorf for measuring ambient dose equivalent, H*(10), in photon radiation fields. After a prototype design phase using a novel combination method of experimental and Monte Carlo simulation techniques the dosemeter is now in its test and optimization phase. Two versions of the Seibersdorf H*(10) area dosemeter with one and two TL cards each with four TLD-100 chips are investigated. Dosimetric and practical properties are evaluated according to standard (ÖNORM, DIN, IEC) recommendations and correction methods for various influence quantities (individual detector sensitivity, energy and angular response, coefficient of variation, linearity) are developed. Additionally, uncertainty estimates of those influence quantities are presented and discussed based on a dosimetric model containing average TL readings up to 1 Sv.
