某1 MeV工业电子加速器辐照室内部及周围臭氧浓度监测与评价

Monitoring and Evaluation of Ozone Concentration in and Around a 1 MeV Industrial Electron Accelerator

为掌握1 MeV工业电子加速器辐照室内部及周围臭氧浓度,判断加速器开机产生的臭氧对周围环境、物体及人体的影响,本研究按国家标准规范对某1 MeV工业电子加速器辐照室内部及周围臭氧浓度进行为期两日的监测。监测结果表明,加速器辐照室内臭氧浓度范围值为0.075～0.077 mg/m^3,室外臭氧浓度范围值为0.034～0.058 mg/m^3。辐照室在保持通风状态时,内部及周围臭氧浓度均远低于国家标准要求,对人体及设备不会产生不良影响。

In order to know the ozone concentration in the interior and surrounding of the 1 MeV industrial electron accelerator irradiation chamber and determine the influence of the ozone generated by the accelerator on the surrounding environment, objects and human body, this study was conducted in accordance with national standards for the irradiation of the interior of a 1 MeV industrial electron accelerator chamber and its surroundings. The concentration was monitored over two days. The monitoring results show that the range of ozone concentration in the accelerator irradiation chamber is 0.075 ～ 0.077 mg/m3, and the range of outdoor ozone concentration is 0.034 ～0.058 mg/m3. When the irradiation chamber is maintained in a ventilated state, the concentration of ozone inside and around is far below the national standard, and no adverse effects on the human body and equipment.
