Abstract

This paper proposes a method for evaluating the standard uncertainty in the measurements with passive personal dosemeters using a numerical method (Monte Carlo). The paper builds on a previous paper where a two-stage measurement model for passive dosemeters was proposed. This model follows the course of events during the measurement, which also consists of two stages: (1) the exposure of the dosemeter in the workplace where a signal develops in the form of, e.g. electron/hole pairs in solid-state detectors and film or damages to a molecular structure in track films, the latent signal and (2) the evaluation at the service where the latent signal is ‘developed’ into an observable signal. In this paper, the study is extended to multielement dosemeters that have multiple outputs. The charm of the proposed method is that it needs no mathematical approximations and does inherently include any correlations that may exist between input quantities and, in the case of multiple outputs likeHp(10) andHp(0.07), between these outputs.
