Description
Summary:Due to the necessity of pilot scale test facility for continuous treatment of wastewater and gases on site, a mobile electron beam irradiation system mounted on a trailer has developed. This mobile electron beam irradiation system is designed for the individual field application with self-shielded structure of steel plate and lead block which will satisfy the required safety figures of International Commission on Radiological Protection (ICRP). Shielding of a mobile electron accelerator of 0.7MeV, 30mA has been designed and examined by Monte Carlo technique. Based on a 3-D model of electron accelerator shielding which is designed with steel and lead shield, radiation leakage was examined using the Monte Carlo N-Particle Transport (MCNP) Code. Simulations with two different versions (version 4c2 and version 5) of MCNP code showed agreements within statistical uncertainties, and the highest leakage expected is 5.5061×10−01 (1±0.0454) μSv/h, which is far below the tolerable radiation dose limit for occupational workers. This unit could treat up to 500m3 of liquid waste per day at 2kGy or 10,000Nm3 of gases per hour at 15kGy. •A mobile electron beam irradiation system mounted on a trailer has developed.•It is designed for treatment of wastewater and flue gas on site.•Shielding of 0.7MeV, 30mA accelerator has done by a Monte Carlo technique.•It can treat up to 500m3/d of liquid waste at 2kGy or 10,000Nm3/h of gas at 15kGy.
