For these reasons it is important to measure accurately and nondestructively the chemical content of bone, with respect to its main elements (Ca, P, Mg, Na) and its trace elements. We have analyzed different types of human bone by instrumental neutron activation analysis (INAA), using a SLOWPOKE reactor. We have compared our results with inductively coupled plasma emission spectroscopy (ICPES), and we have determined the limits of detection and sensitivity for the various elements, especially some biologically or toxicologically significant trace elements. Finally, we have given two examples of the use of INAA in following the penetration of an element (F) with time into bone and in characterizing nondestructively the mineral content of bone biopsies of a rare pathological condition (osteopetrosis).

The vertebral density was determined by photon absorptiometry. 119 caudal vertebrae from the skeletal collection were analyzed chemically. Cortical mineral density and porosity increased with age, and vertebral density and cortical area increased with weight. There was significant sexual dimorphism in many histological variables reflecting size differences and cortical porosity was greater in males. The chemical analysis showed no influence of the diet on bone mineral but that Ca increase with age in females but not in males. Finally a subgroup of aged, animals had hypermineralized, and more porous bone. This subpopulation may prove to be a valuable model for senile osteoporosis.

Hair was collected from the scalp, cheeks, and chin from one donor on a regular basis since 1984. Samples were separated into white and pigmented fractions, and analyzed at SLOWPOKE-Toronto by INAA for the short-lived, isotope-producing elements Br, Ca, Cl, Cu, I, Mg, Mn, Na, S, and Zn. Temporal concentration variations of these elements over time, and variations of the elemental concentrations in pigmented and white hair were established.

Results from a study of multiple village sites on the central coast of British Columbia reveal insight into patterns of ochre procurement, distribution and use. Instrumental neutron activation analysis is used to determine the geochemical composition of ochre and to characterize different source groups. The results of this analysis contribute to our understanding of the role of ochre among these culture groups, and furthermore provide an archaeological history of its long-term use.
