Description
相关申请
本申请要求2008年10月6日提交的美国临时申请(申请序列号为61/102,997)的优先权,将该申请全部内容引用于此。
技术领域
本发明通常涉及一种在辐射屏蔽应用中使用的组合物。
背景技术
辐射屏蔽结构的应用非常广泛,尤其在核技术领域和任何产生辐射的设备中。典型的辐射源包括宇宙射线、医疗设备中的X-射线、核反应堆、阴极射线管(如电视和电脑显示器)等等。在多种装置中都需要仔细检测辐射剂量,人体照射水平的管理标准也有很多。辐射屏蔽在限制辐射对敏感设备的照射量上也十分重要。例如,要保护核反应容器不受γ射线的照射。再比如,需要对其它医疗设备进行保护,以免受到放射辐射的医疗设备的影响。
混凝土或水泥是辐射屏蔽中常用的候选材料。例如,美国专利No.5,786,611曾提出储存用过的核废料的容器,该容器含具有稳定的氧化铀集料的混凝土和B2O3、HfO3或者Gd2O3等中子吸收材料。美国专利No.4,727,257曾提出一种辐射屏蔽组合物,其含基于含集料的水泥的灰浆(mortar),其中集料含抹灰凝胶剂(floated gelata)和硼矿物(boron mineral)。美国公开No.2002/0165082曾提出一种磷酸盐陶瓷辐射屏蔽组合物,其含镁、钾和磷粘合剂,以及用于散热的物质例如B4C、Bi2O3、Fe2O3、Fe3O4、Pb金属和铅。
但是,目前仍需要一种成本较低、较少依赖重金属的组合物用于提供可接受水平的辐射屏蔽。
发明内容
辐射屏蔽结构在核电厂、粒子加速器、研究堆、实验室设备和放射线与X射线医疗设施的屏蔽中被广泛应用。重要的因素是选择具体的屏蔽结构作为所需的衰减系数(attenuation coefficient)或缩减因子(reduction factor)。线性衰减系数(μ)取决于屏蔽材料的密度。为了避免由于材料密度不同所带来的影响,线性衰减系数表示成质量衰减系数(mass attenuation coefficient)(μ/ρ)cm2g-1,它是表示单位质量的屏蔽材料的效果的直接量度。
为此,本发明提供了一种辐射屏蔽结构组合物,其含硅酸钙、氧化镁和酸式磷酸盐。该辐射屏蔽结构,基于为0.662MeV(5μCi Cs-137源)和1.173MeV(1μCi Co-60源)的光子能量,与普通的混凝土相比具有改进的衰减系数。
在另一个实施方案中,本发明提供了一种辐射屏蔽结构组合物,其含氧化镁或氧化钙、酸式磷酸盐和粉煤灰,并且基于为0.662MeV(5μCi Cs-137源)和1.173MeV(1μCi Co-60源)的光子能量,与普通的混凝土相比具有改进的衰减系数。
在另一个实施方案中,本发明提供了一种辐射固化结构组合物(radiation curing structure composition),其含氧化镁或氧化钙、酸式磷酸盐和高岭土,并且基于为0.662MeV(5μCi Cs-137源)和1.173MeV(1μCi Co-60源)的光子能量,与普通的混凝土相比具有改进的衰减系数。
附图说明
图1是使用5mCiCs-137源,光子能量为0.666MeV时实施例1-6中的辐射屏蔽结构组合物与普通混凝土(“OC”)的衰减系数图。
图2是使用1μCiCo-60源,光子能量为1.173MeV时实施例1-6中的辐射屏蔽结构组合物与普通混凝土(“OC”)的衰减系数图。

在另一个实施方案中,辐射屏蔽结构含氧化镁或氧化钙、和酸式磷酸盐以及高岭土。在一个实施方案中,该结构含15-40重量%的煅烧氧化镁或氧化钙、25-55重量%的酸式磷酸盐,20-40重量%的粉煤灰。
在另一个实施方案中,辐射屏蔽结构含氧化镁或氧化钙、酸式磷酸盐和高岭土。在一个实施方案中,该结构含15-40重量%的煅烧氧化镁或氧化钙、20-55重量%的酸式磷酸盐和5-25重量%的高岭土。
典型的酸式磷酸盐包括磷酸二氢钾、磷酸镁、磷酸钠、磷酸铝、磷酸铵、磷酸铁、磷酸锌及上述物质的组合。在上述实施方案中,酸式磷酸盐可以是磷酸二氢钾。
辐射屏蔽结构组合物可以混合适当的添加剂,通常情况下添加剂的重量为约0.1到约30重量%。典型的添加剂包括阻燃剂、蛭石、珍珠岩、纤维、乳化剂、抗凝剂、螯合剂、粒状添加剂、石块或沙粒等粗集料、硼酸等化学添加剂、促进剂(如The Euclid Chemical Company,Cleveland,Ohio生产的Accelguard)、着色剂和颜料、填料、集料、硼砂、硅土料、铁氧化物、胶粘剂(如The Euclid Chemical Company,Cleveland,Ohio生产的Eucopoxy树脂和Eucoweld、Flexcon和Corr-bond)、塑化剂、硬化剂(如The Euclid ChemicalCompany,Cleveland,Ohio生产的Euco Diamond Hard)、修补聚合物(如The EuclidChemical Company,Cleveland,Ohio生产的Eucorapid补料(Eucorapid patch))、微二氧化硅粉(如The Euclid Chemical Company,Cleveland,Ohio生产的Eucoshot)、缓凝剂、表面软化剂、和高岭土、固化化合物(如Brownstone CS)、减水剂(如Accelguard,Eucon AC)及空气夹带剂(如AEA和Air Mix)。
或者,在辐射屏蔽结构组合物中也可添加中子吸收剂。典型的中子吸收剂包括重金属和重金属化合物例如硼、B2O3、HfO3、Gd2O3、氧化铁、铅等等。
或者,在该组合物中可以添加各种加固成分(reinforcement),或者该组合物可用于加固成分。典型的加固成分包括钢(例如钢筋)、其他金属(例如铅)、碳、玻璃、石料、玄武岩等,其为纤维、颗粒和/或织物/垫的形式。
该辐射屏蔽结构组合物可混合为浆料并喷洒在现有表面或基质上,用以提高该表面的衰减系数,或者浆料也可以经喷射、挤压、成模等制成预定的形状。适当的结构包括核电厂、粒子加速器、研究堆、X-射线设备、辐射设备等的屏蔽罩。其他结构还有诸如2009年10月2日提交的美国系列号No._,【代理人卷号No.9591-8】所描述的用于发射有害性辐射的废物的运输和储存容器,该申请所揭露的所有内容引入此作为参考。
