ABSTRACT:
Personal dosimeter, which provides great ease in immediately obtaining reading results, includes a plastic tube, open on the bottom, and containing near its top, a well through the bottom of which is inserted a piece of inert wick and a cover made of a soft plastic placed over the top of the tube. When the dosimeter is to be put into use, a predetermined amount of liquid reagent is injected into the well formed near the top, which reactant moves by capillary action into the inert wick where it adsorbs, absorbs or reacts with a toxic substance to be measured by the dosimeter. After the required time period for measuring exposure, the dosimeter is turned over, additional reactant placed in the tube from the bottom and mixed with the reactant therein, the reactant then being used to determine the concentration of the toxic substance.
