Abstract: A substantially immobile ''''non-shifting'''' relatively low energy radiation source includes a particulate radioisotope bearing material positioned within a chamber formed in a capsule. Movement of the radioactive isotope element or any attenuating mass is prevented by a porous deformable conformational barrier member which has pores therein smaller than the smallest particle adjacent to the barrier and which prevents any attenuating producing movement of any particulate material within the capsule. In the case of gas producing radioisotopes, provision is made to permit escape of gas while preventing movement of attenuating masses or radioactive isotope material. Various radioisotopes and barrier members are described as well as various ways to assemble a ''''non-shifting'''' source.
Abstract translation: 基本上不能移动的“非移动”相对较低的能量辐射源包括定位在形成在胶囊中的腔室内的颗粒状放射性同位素轴承材料。 放射性同位素元素或任何减弱物质的移动通过多孔可变形构象阻挡构件来防止，该多孔可变形构象阻挡构件的孔隙小于与屏障相邻的最小颗粒，并且防止任何减弱的胶囊内任何颗粒物质的运动。 在产生放射性同位素的气体的情况下，提供允许气体逸出同时防止衰减的质量块或放射性同位素材料的移动。 描述了各种放射性同位素和阻挡构件，以及组装“不移动”源的各种方式。
