摘要： This invention relates to compositions, methods of production and uses of materials for shielding against nuclear radiation. These materials are made of a low density solid hydrogenous material which binds a powder of medium density materials. They are particularly effective for shielding against fission and high energy neutrons, as well as against a combined radiation of neutrons and photons.

摘要： Solid protective elements such as cesium, thallium or luletium are dispersed in or layered on an object so that when a high energy laser beam strikes the object a highly ionized plasma is provided that absorbs or reflects the laser beam. Alternately, the object to be protected is surrounded with a gaseous protective element such as krypton or xenon.

摘要： There is described an apparatus for the corrosion protection of containers for the long time storage of radioactive materials, especially of spent fuel elements, in suitable geological formations which avoid corrosion of the container even with unexpected occurrence of water, or at least delay and minimize the corrosion. The apparatus consists essentially of sacrificial anodes 2 which are conductively joined to the containers 1 via connections 3.

摘要： A method of fabricating very fine metal screens for use in a transparent or translucent panel through which visible light is transmittable but which acts as a barrier against transmissions of pulsed electromagnetic radiation which may be harmful to humans or disruptive to electronic gear. The screens are fabricated by printing a pattern photographically upon a first surface of a metal foil covered on both sides by a positive, photo sensitive etchant mask and removing exposed areas of the mask with a developer. The masked foil is then chemically blanked by application of an etchant to the first side only of the foil. The specimen is rotated 90 degrees on a frequent basis to prevent selective etching, especially in areas adjacent the periphery of the screen. The protective mask and the mask on the second side of the foil are then exposed to light and removed from the screen leaving a screen presenting minimum optical distortion and visual blocking therethrough and possessing unimpeded electrical conductivity in all directions.
摘要翻译： 一种制造用于透明或半透明面板的非常精细的金属屏幕的方法，通过该屏幕，可见光可透射，但其作为阻止可能对人类有害或脉冲到电子齿轮的脉冲电磁辐射的屏障。 通过用积极的光敏蚀刻剂掩模在双面覆盖的金属箔的第一表面上照相地印刷图案来制造屏幕，并用显影剂去除掩模的暴露区域。 然后通过将腐蚀剂施加到箔的第一侧而将掩模的箔化学消隐。 频繁地将样品旋转90度以防止选择性蚀刻，特别是在与屏幕周边相邻的区域中。 然后将保护面罩和箔的第二面上的掩模曝光并从屏幕上移除，留下屏幕，其具有最小的光学变形和视觉遮挡，并且在所有方向上具有无阻碍的导电性。

摘要： A shielding means for an x-ray machine comprised of a base plate which removably receives overlays masking out selective portions of the base plate to control the passage of the x-rays therethrough. The overlays are generally identical and provided with co-operating removable securing means to permit the same to be stacked one on the other to vary the thickness thereof. Removable mounting rails position and maintain the shielding means on the x-ray machine.

摘要： The invention relates to novel cathode-ray/vacuum tubes for color television. It was found that the present color television tubes emit considerable amount of X-radiation. The novel tubes described below are characterized by the X-ray absorbing faceplate which prevents the escape of such X-radiation or at least reduces the amount of said escaping X-radiation to the level which is safe for the public. These tubes have a construction in which their light transparent endwall on which the fluorescent screen is mounted has the X-ray absorbing power to accomplish this objective, which means to reduce the transmission of X-ray through said endwall to the amount smaller than 0.04 mr./hr. in addition the faceplate of said tubes is provided with a light partially absorbing material which means light filtering material to improve the contrast of images produced by said tubes.
