In order to improve the safety performance of a γ-irradiator to meet related standards, an interlock system based on programmable logic controller was designed. By the ladder diagram design, the system realized the sequential inspection, delay timer, exception alarm and son on. The results show that the programmable flexible design is advantageous in improving safety of the irradiator.
