Description

The aim of this work is to present the methods in use for environmental dose assessment with passive detectors at Campus Tecnologico e Nuclear (CTN) of Instituto Superior Tecnico, in Portugal. The methods are based on LiF:Mg,Ti (TLD-100) detectors inserted in Harshaw holders placed at four locations and exchanged on a quarterly basis. An initial group of measurements allowed the estimation of the time interval necessary to attain a stable value, the determination of a fading factor, as well as the calculation method for the assessment of the ambient dose equivalent rate.
