射線防護門在一些醫(yī)療場所的應(yīng)用較為廣泛，主要用于需阻擋射線通過的進出口，機房和礦區(qū)中。主要應(yīng)用于射線防護，其一般作用于屏蔽室、高和低能量直線加速器室、質(zhì)子室、放射外科室、CT圖像引導(dǎo)調(diào)強放射室、IMRT/IGRT室等。對保障工作人員的健康和防止射線對外擴散而引起不必要的傷害起到了關(guān)重要的作用。
Radiation protection door is widely used in some medical places, mainly used in the import and export, machine room and mining area which need to block the ray. It is mainly used in radiation protection. It is generally used in shielding room, high and low energy linear accelerator room, proton treatment room, radiosurgery treatment room, CT image-guided intensity-modulated radiation therapy room, IMRT / IGRT room, etc. It plays an important role in protecting the health of workers and preventing unnecessary injury caused by the external spread of radiation.
為適應(yīng)醫(yī)學檢查室的設(shè)計特點，在選擇射線防護用品的要求上也需要有針對性。如，不同的射線防護門類型就存在著較大的結(jié)構(gòu)設(shè)計差異，為此，我們就先來了解一下射線防護門有哪些設(shè)計形式：
In order to adapt to the design characteristics of medical examination room, the requirements of selecting radiation protection equipment also need to be targeted. For example, different types of radiation protection doors have great differences in structural design. Therefore, let's first understand the design forms of radiation protection doors
一：平開防輻射鉛門，可分為內(nèi)開門和外開門，門體的結(jié)構(gòu)和材料是根據(jù)放射線機的功率大小(KV)及門洞口大小來決定的，五金件為進口專用件。
1： The structure and material of the door body are determined according to the power (kV) of the radiation machine and the size of the door opening. The hardware parts are imported special parts.
二：推拉防輻射鉛門，開啟方向是沿著墻壁平行移動，門體的結(jié)構(gòu)與
2： Push and pull the radiation proof lead door, and the opening direction is parallel to the wall
二：推拉防輻射鉛門，開啟方向是沿著墻壁平行移動，門體的結(jié)構(gòu)與材料是根據(jù)放射線機的功率大小(KV)及門洞口大小來決定的，門框結(jié)構(gòu)與平開門結(jié)構(gòu)有所區(qū)別。
2： The opening direction of push-pull radiation proof lead door is parallel to the wall. The structure and material of the door body are determined by the power of the radiation machine (kV) and the size of the door opening. The door frame structure is different from the side door structure.
三：電動防輻射鉛門一般適合較大的門體，由于重量較重，人力開啟比較吃力，所以采用電動開啟方式。開啟形式可分為平開式和平移式。
3： The electric radiation proof lead door is generally suitable for larger door body. Due to its heavy weight and hard manual opening, the electric opening mode is adopted. Open form can be divided into flat open type and moving type.
鉛玻璃里面含有鉛，能夠有效的防止輻射，所以多應(yīng)用在醫(yī)院等輻射較多的地方。鉛玻璃雖然是含有氧化鉛，但是其外表看起來是透明的。只是稍微發(fā)黃色，但是并不明顯。防護玻璃一般指防X射線或γ射線或防中子的玻璃。由于物質(zhì)對放射性輻射的吸收能力隨其含有的金屬元素的原子序數(shù)的增大而提高，所以防護玻璃都含有較多量的重金屬氧化物。例如防X射線玻璃含較多量的PbO、BaO等，防γ射線的玻璃含較多量的PbO、WO3、Bi2O3等。由于γ射線的穿
Lead glass contains lead, can effectively prevent radiation, so it is widely used in hospitals and other places with more radiation. Although lead glass contains lead oxide, its appearance is transparent. It's just a little yellow, but it's not obvious. The protective glass generally refers to the glass which can prevent X-ray, gamma ray or neutron. As the absorption capacity of materials to radioactive radiation increases with the increase of atomic number of metal elements, protective glass contains more heavy metal oxides. For example, the anti X-ray glass contains more PBO and Bao, while the anti gamma ray glass contains more PbO, WO3, Bi2O3, etc. Because of the penetration of gamma rays由于γ射線的穿透能力較X射線強得多，所以γ射線防護玻璃的比重和鉛當量較X射線防護玻璃高得多。
Because the penetration ability of gamma ray is much stronger than that of X-ray, the specific gravity and lead equivalent of γ - ray protective glass are much higher than that of X-ray protective glass.
鉛玻璃的主要性能在光學上是清楚的、透明的防護屏蔽而使用的一種具有規(guī)定衰減性能的低光學質(zhì)量的防護玻璃板,其衰減性能每一毫米為0.22mmpb。醫(yī)用鉛玻璃表面涂敷涂料當時，絕關(guān)于來說把金屬表和條件隔開了，這種維護效果可稱為屏障效果。
The main performance of lead glass is clear and transparent in optical protection. A low optical quality protective glass plate with specified attenuation performance is used. Its attenuation performance is 0.22mmpb per millimeter. Medical lead glass surface coating, absolutely speaking, separated the metal surface and conditions, this maintenance effect can be called barrier effect.
