Abstract: A company is equipped with a horizontal industrial electronic irradiation accelerator to irradiate the cable due to production needs and the height restrictions of the existing workplace. The main unit of the accelerator is installed on the equipment platform and shielded with lead plate & steel plate. Due to unqualified testing, additional lead plates were attached later. The effectiveness and economy of this protection method are analyzed by combining theoretical calculation results and field verification test results.

Key words: Industrial electronic irradiation accelerator, Protection design, Theoretical calculation, Verification test
