Pollution control equipment

直接观察操作开放型放射性物质，通常都在有适当通风的通风柜或手套箱内进行。

Direct observation of open radioactive materials is usually carried out in a properly ventilated fume hood or glove box.

通风柜

Fume hood

通风柜是放射性同位素实验室常用的污染控制设备.可根据操作放射性核素的种类、活度、操作性质等进行设计。其主体结构宜采用不锈钢制作通常为尺寸通常为1.2-1.8mx0.8-0.85mx 1.5m(长 x深x 高 )，将其放置在试验台而上。

Fume hood is a common pollution control equipment in radioisotope laboratory. It can be designed according to the type, activity and operation property of radionuclides. The main structure should be made of stainless steel, usually with the size of 1.2-1.8mx0.8-0.85mx 1.5m (length x depth x height), and placed on the test bench.

其操作面宜采用平衡拉窗，（可分两扇)式.拉窗上安装硅酸盐玻璃;过滤器设置在通风柜的上部，采用离心式排风机，将其安装在顶部，以便使废气管道内保持负压;通风柜操作口的截面风速应不小于Im.s-1，并利用自动的旁路来防止柜门关闭时，风速的骤然增加。

The operation surface should adopt balanced sliding window, which can be divided into two types; The filter is arranged on the upper part of the fume hood, and the centrifugal exhaust fan is adopted, which is installed on the top, so as to maintain negative pressure in the waste gas pipeline; The cross-section wind speed of the fume hood operation port shall not be less than im. S-1, and the automatic bypass shall be used to prevent the sudden increase of wind speed when the cabinet door is closed.

通风柜的内表面应采用易去污材料.如不诱钢板或PVC板。拒的底部可采用耐酸瓷砖或不锈钢板;柜内设置煤气、冷热水、污水排出口;用暗装日光灯作为通风柜内部照明.其照明标准为150一300 Lx(勒克斯)，电源插座设置在通风柜外部。

The inner surface of the fume hood shall be made of easily decontaminated materials, such as stainless steel plate or PVC plate. Acid resistant ceramic tile or stainless steel plate can be used at the bottom of the filter; Gas, hot and cold water and sewage outlets are set in the cabinet; The lighting standard is 150-300 LX, and the power socket is set outside the fume hood.

电动推拉门、电动平开门：门体钢骨架结构，上悬挂地轨两种载荷方式，设计铅当量1-6mmpb，双面外饰不锈钢板或钢塑板，铝塑板等外饰面，配置:进口、国产精密电脑控制电动门机，红外传感器，光电限位，两组固定按钮，遥控开关，门机联锁，辐射警示标志，工作指示灯。
