[Use of x-ray spectral microanalysis for studying mineralized tissues].
In microanalysis of mineralized tissues an x-ray spectral method possessed an absolute limit of sensitivity about 5-10 minus 15 g. A relative limit of the method sensitivity constituted hundredth parts of a per cent and locality of the analysis--several cubic microns. The x-ray spectral microanalysis permitted to carry out qualitative and quantitative estimations of content of elements in different structures of biological tissues. The data were obtained on content of calcium and phosphorus in compact part of human tubular bone.
