This computer-based tool is used to calculate the concentration in mg/m³ that is equivalent to a "non-detected" result for a passive dosimeter. This downloadable file was directly inspired by the preliminary work of Louise Pâquet, an industrial hygienist on CLSC Montréal-Nord's occupational health team. A 3M passive dosimeter user's guide is also available.
