Abstract
A chemical dosimeter improved for individual use which gathers particles or vapours in a filter which are present in an air current pumped through the dosimeter at a constant velocity, the improvement is the use of a controllable pump which is connected to the filter, driven by an electric motor and is controlled by a feedback circuit of an integrator and an amplifier and maintains a constant flow of air through the dosimeter; the integrator receives a signal from a pressure switch that detects flow changes in the air current through the dosimeter through a change in a drop in the air pressure which is pumped through a hole; the dosimeter is carried by an individual, and after a period of time, for example, one working day, the filter is removed and the contents gathered are analysed by conventional techniques such as gas chromatography in order to determine the level of exposure of the individual who used the dosimeter.
