Self-shielded e-beam for polymer industries

Industrial electron accelerators have been used for cross-linking and modification of polymeric products and such demand for highly-reliable, compact equipment has promoted the design of self-shielded system. The self-shielded accelerators, with stainless steel and lead, make it possible to avoid construction of special buildings, as well as to make effective use of space. Depending on the applications, the energy of accelerated electrons is in the range of 0.05 ∼ 0.7 MeV and the beam power up to 20 kW. The self-shield structure also varies with electron energy and applications, such as processing of polymer film, sheet and other materials. And the self-shield structures are designed to fit the guideline of International Council for Radiation Protection (ICRP) and the regulation of Korean Government with Monte Carlo simulation methods (MCNP).
