Dose estimation in thin plastic tubings and wires irradiated by electron beam

High energy ionising radiation can be used to beneficially change the properties of plastic materials used in the manufacture of coated wires, cables and extruded tubings. For realisation of this process it is preferable to use electron accelerators as radiation sources. In the present study a scanned 2-MeV electron beam was used to irradiate the simulated objects and the real products. The determination of absorbed dose distribution in the irradiated objects was performed by using the thin polyethylene film equivalent to the insulating material. Equations of dose evaluations for 'figure eight' irradiation technique for the real products (thin wires and tubes) are given. (author)
