On the one hand, the progress of science and technology brings convenience to our life and production, but at the same time, it also brings us some adverse effects. Radiation poses a serious threat to our health. With the deepening of people's understanding of radiation, more and more attention has been paid to radiation protection, and various radiation protection materials have emerged as the times require.

放射線防護(hù)服防護(hù)材料，以往對(duì)高輻射劑量多用鉛細(xì)纖維，對(duì)低劑量多用鉛系粉末與橡膠、塑料等填充層制成。

In the past, the protective materials for radiation protective clothing were mainly made of fine lead fibers for high radiation dose and filling layers for low radiation dose, such as lead powder, rubber and plastics.

鉛細(xì)纖維由于重復(fù)彎曲、而引起鉛纖維斷裂，導(dǎo)致屏蔽不良。另外用鉛系粉末與橡膠、塑料制成的填充材料，為了達(dá)到良好地屏蔽效果，須要做得非常厚，結(jié)果撓性變差。

Lead filament breaks due to repeated bending, resulting in poor shielding. In addition, filling materials made of lead powder, rubber and plastics must be very thick in order to achieve good shielding effect, resulting in poor flexibility.

目前鉛玻璃主要分為兩類，類為無機(jī)鉛玻璃當(dāng)前在我國(guó)應(yīng)用比較廣泛，另-類為有機(jī)鉛玻璃,這種鉛玻璃比無機(jī)鉛玻璃耐沖擊性要高但不耐鹼和酒精無機(jī)鉛玻璃主要用于X射線機(jī)房、CT機(jī)房、ECT機(jī)房等觀察窗和制作鉛眼鏡用,有機(jī)鉛玻璃除上述應(yīng)用外,由于該種材料易于加工、質(zhì)輕、耐沖擊性能強(qiáng)、透明性好,因此還廣泛用于制作各種防護(hù)屏風(fēng)和其它防護(hù)用品,如防護(hù)面罩等.

At present, lead glass is mainly divided into two categories, one is inorganic lead glass which is widely used in our country, the other is organic lead glass. This kind of lead glass has higher impact resistance than inorganic lead glass, but not alkali-resistant and alcohol-resistant inorganic lead glass is mainly used for X-ray machine room, CT machine room, ECT machine room and other observation windows and for making lead glasses. In addition to the above applications, glass is also widely used to make various protective screens and other protective devices, such as protective masks, due to its easy processing, light weight, strong impact resistance and good transparency.

建材類射線防護(hù)的防護(hù)材料指的是各種類型的混凝土、磚、重晶石、防護(hù)涂料(填料)、成型防護(hù)板材或板塊等用于射線裝置機(jī)房、放射源室、輻照室、核設(shè)施等基建屏蔽防護(hù)工程的防護(hù)材料.在實(shí)際應(yīng)用中,應(yīng)根據(jù)射線源的種類、強(qiáng)度、能量和防護(hù)材料的特性來設(shè)計(jì)符合防護(hù)要求的基建異蔽設(shè)施.

Radiation protection materials for building materials refer to various types of concrete, bricks, barite, protective coatings (fillers), forming protective plates or plates used in radiation equipment room, radiation source room, irradiation room, nuclear facilities and other protective materials for infrastructure shielding and protection projects. Strength, energy and properties of protective materials are used to design infrastructure shelter that meets the protection requirements.
