目的分析某轮胎公司X射线轮胎检测系统对周围环境的辐射影响。方法依据国家相关标准规定的限值及监测方法作为评价标准和监测手段。结果 X射线机非工作状态下,检测室周围环境X、γ空气吸收剂量率监测结果范围为43.7~71.3 nGy/h,处于该市天然放射性本底水平范围内。X射线机工作状态下,检测室周围环境X、γ空气吸收剂量率监测结果范围为45.5~73.9 nGy/h,监测值均低于《工业X射线探伤放射卫生防护标准》(GBZ 117-2006)所规定的2.5μGy/h的标准限值。结论该项目对职业工作人员和公众人员是安全的,对周围环境产生的影响较小。
Objective To analyze the radiation effects on the surrounding environment of a tire company’s X-ray tire testing system. Methods Based on the limits and monitoring methods stipulated by relevant national standards, the method was used as the evaluation standard and monitoring method. Results X-ray machine non-working state, the detection room ambient X, γ air dose rate monitoring results range 43.7 ~ 71.3 nGy / h, in the city’s natural radioactive background level range. X-ray machine working conditions, the ambient air around the detection room X, γ air dose rate monitoring results range 45.5 ~ 73.9 nGy / h, the monitoring values were lower than the “X-ray industrial radiological testing” (GBZ 117-2006) The standard limit of 2.5 μGy / h is specified. Conclusion The project is safe for professional workers and public officials with little impact on the surrounding environment.
