Abstract

We report changes in Young's Modulus and breaking strength in compact costal porcine bone (Yorkshire breed, n = 9) subjected to escalating doses up to 4.0 Gy of fast neutrons, from a ⁷Li(p,n)⁷Be reaction. The mean neutron energy was 233 keV. Decreases in both Young's Modulus and breaking strength as functions of increasing neutron dose, were observed.

Keywords: Breaking strength; Cortical bone; Costal bone; Fast neutron dose; Porcine bone; Young's modulus.
