Pollution control equipment

直接觀察操作開放型放射性物質，通常都在有適當通風的通風櫃或手套箱內進行。

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

通風櫃

Fume hood

通風櫃是放射性同位素實驗室常用的汙染控製設備.可根據操作放射性核素的種類、活度、操作性質等進行設計。其主體結構宜采用不鏽鋼製作通常為尺寸通常為1.2-1.8mx0.8-0.85mx 1.5m(長 x深x 高 )，將其放置在試驗台而上。

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.

其操作麵宜采用平衡拉窗，（可分兩扇)式.拉窗上安裝矽酸鹽玻璃;過濾器設置在通風櫃的上部，采用離心式排風機，將其安裝在頂部，以便使廢氣管道內保持負壓;通風櫃操作口的截麵風速應不小於Im.s-1，並利用自動的旁路來防止櫃門關閉時，風速的驟然增加。

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.

通風櫃的內表麵應采用易去汙材料.如不誘鋼板或PVC板。拒的底部可采用耐酸瓷磚或不鏽鋼板;櫃內設置煤氣、冷熱水、汙水排出口;用暗裝日光燈作為通風櫃內部照明.其照明標準為150一300 Lx(勒克斯)，電源插座設置在通風櫃外部。

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.

電動推拉門、電動平開門：門體鋼骨架結構，上懸掛地軌兩種載荷方式，設計鉛當量1-6mmpb，雙麵外飾不鏽鋼板或鋼塑板，鋁塑板等外飾麵，配置:進口、國產精密電腦控製電動門機，紅外傳感器，光電限位，兩組固定按鈕，遙控開關，門機聯鎖，輻射警示標誌，工作指示燈。
