| Abstract: | A device consisting of poly allyl diglycol carbonate (PADC) foils with a polyethylene and polyvinyl chloride (PVC) radiator
was calibrated in order to perform the dosimetry of an 241Am-Be source covering a dose range from 0 to 3.1 mSv. Working conditions were established for a good visualization and counting
of tracks: chemical attack was made in two steps with different solutions and etching times. A good fit was obtained for the
dose as a function of the number of tracks per unit surface area. The calculated decision threshold was 0.12 mSv. |
