在许多受(137)Cs意外照射的病例中,其治疗可能是在事故发生后耽搁几小时甚至数天才进行的,因此存留在体内的铯在着手治疗前就有可能沉积在细胞内。铯离子在体内的行径类似钾离子。两者在细胞内的浓度均高于细胞外液,但细胞内外之间存在动态平衡。此外,不断地分泌到小肠腔内的细胞外的铯,当通过肠道时大部分又被重新吸收。因此,即使相隔几天或数月之后,肠液中仍会有少量的铯。这反映了正常机体代谢过程中细胞内铯的更新。正是这种铯能同昔鲁士兰(P、B)和在治疗铯沾染中所使用的其它
In many cases of accidental exposure to (137) Cs, treatment may be delayed for hours or even days after the accident, so cesium retained in the body is likely to deposit inside the cell prior to initiating treatment. Cesium ions act like potassium in the body. The concentration of both in the cell than the extracellular fluid, but there is a dynamic balance between the inside and outside the cell. In addition, extracellular cesium secreted continuously into the small intestine cavity is mostly reabsorbed when passing through the intestine. Therefore, even after a few days or months later, there will be a small amount of cesium in the intestinal fluid. This reflects the renewal of intracellular cesium during normal metabolism. It is this cesium that can be used in combination with celulose (P, B) and others used in the treatment of cesium contamination
