Emission Mössbauer spectra and Perturbed Angular Correlation measurements have been performed on samples of mineral bone powder labelled with 161Tb3+ or 133Ba2+ ions after either in vitro absorption or uptake by metabolic pathway. The study of these hyperfine spectra, compared with those carried out when 161Tb or 133Ba are situated in either hydroxyde lattice or phosphate one, shows that the uptake modes of rare-and alkaline-earth ions on the bone matrix are different. The rare earth ion seems to be absorbed on the surface bone in an environment of hydroxyl groups similar to the structure of a rare earth hydroxyde. The alkaline earth ion bone uptake appears more complicated and would make according to the following process : at first, surface absorption on the hydroxylapatite in a hydroxyde environment and then cationic exchange with the calcium phosphate groups into bone crystals.
在用161Tb3 + 或133Ba2 + 离子标记的矿化骨粉样品经体外吸收或通过代谢途径摄取后，进行了发射穆斯堡尔光谱和扰动角关联测量。将这些超精细光谱与161Tb或133Ba位于氢氧化物晶格或磷酸盐晶格中时所进行的光谱研究相比较，结果表明，稀土离子和碱土离子在骨基质上的摄取模式是不同的。稀土离子似乎在类似于稀土氢氧化物结构的羟基环境中被吸收到骨表面。碱土离子对骨的摄取似乎更为复杂，可能按照以下过程进行：首先，在氢氧化物环境中表面吸收到羟基磷灰石上，然后与骨晶体中的磷酸钙基团进行阳离子交换。
