Abstract: A kit of parts is for assembling a diffusive dosimeter for the detection of pollutants, said kit of parts includes a housing (1, 50), a first adsorbant (2) to be placed inside the housing and a first spacer (3) to be placed on top of the adsorbant, to define a thickness (L) and a first surface area (A) of a diffusive layer. The kit also has a first protective layer (5) placed on top of the spacer and a first cover (6) having an opening (7), to be placed on top of the protective layer, in a manner to close off the assembled dosimeter at its circumference. The kit has at least one or more additional spacers (15,16,17), each additional spacer being able to replace the first spacer and each spacer defines a different surface area, so that each spacer allows a measurement with a different uptake rate.
