V. Foltynova et al., A COMPARISON OF SODIUM AMOUNTS IN COMPACT-BONE, RED MARROW AND YELLOWMARROW SECTIONS AS DETERMINED BY INSTRUMENTAL NEUTRON-ACTIVATION ANALYSIS, Journal of radioanalytical and nuclear chemistry, 201(6), 1995, pp. 477-480
Sodium was determined by the use of instrumental neutron activation an
alysis in sections of compact bone, red marrow and yellow marrow to ch
eck possible effects of soft tissues in the bone when determining the
Na/Ca ratio in sections of the undecalcified bone tissue. The results
indicated that this ratio actually reflects the sodium content in the
bone mineral, the contribution from the soft tissues being two orders
of magnitude lower.
