- Abstract
- The demand for industrial using through accelerators is increasing. There are variousmethods to measure the absorbed dose of the sample irradiated with electron beam, but amongthese, a comparatively easy and simple method is used to evaluate the B3 film dosimeter developedby the Riso Institute of Denmark. Accordingly, the B3 dosimeter was used to check the PenetrationDepth Distribution (PDD) for each medium and determine the optimal dose according to theexperiment. After verifying the linearity of the dose according to the conveyor speed in order tosecure the reliability of the results and confirm the stability of the operation, the experiment wasconducted based on ISO / ASTTM 51649, which is known as a guideline for dose evaluation in thefield of radiation processing. The PDD graph was respectively checked on the Polyethylene (PE),Polyethylene terephthalate (PET), Acrylic, Polyvinyl chloride (PVC) and Aluminum plate withdensity of 0.722, 1.206, 1.289, 1.611, and 2.667 g·cm-3. The optimal depth was reached at about34 cm for low density materials and about 17 to 24 cm for high density. It was verified throughexperiments that it was dominant in density, but it was found that in the case of acrylic, about 5 cmof thickness was required to reach the optimum depth compared to PET with low density. Throughthis, in addition to physical factors such as density, the mechanism according to the binding state ofthe polymer material should be identified and will be studied in the future work.
