Determination of radionuclides in samples of middle-aged and older human femurs.
The paper presents the studies of the presence of gamma isotopes and (90)Sr in 19 middle-to old-aged human femur samples. The samples were taken up during routine orthopedic operations in 2012. The aim of the paper was determination of some radionuclides in human bones and estimation of radiation dose created by (90)Sr and (90)Y (in bones). The (137)Cs, (40)K, (226)Ra, (228)Th, (234)Th and (210)Pb isotopes were determined by gamma spectrometry. The above mentioned radionuclide contents were in the ranges: (137)Cs (0.04-1.45); (40)K (13-86); (226)Ra (1-21.5); (228)Th (1.4-40.2); (234)Th (0.4-5.7); (210)Pb (0.7-8.4) Bq/kg d.w. (90)Sr was assayed based on radiometric measurement of ingrown (90)Y. The (90)Sr content was in the range 0.27-1.85 Bq/kg d.w. Measurements of concentration of (90)Sr and (90)Y in bones were used to estimation of health risk by calculation of radiation dose. Adsorbed doses ranged from 2.7 · 10(-7) to 1.9 · 10(-6) Gy/y for (90)Sr and from 1.2 · 10(-6) to 8.3 · 10(-7) Gy/y for (90)Y.
