Uranium concentration in bone of Beijing (China) residents.
Bone samples were obtained from 65 Beijing residents who had died from illness or old age. The concentration of uranium in the bone ash was determined by the laser-fluorimetric method. The concentration varied between 0.014 and 0.390 microgram g-1 ash, with a median value of 0.067 microgram g-1 ash; the 25th and 75th percentiles were 0.045 and 0.1 microgram g-1 ash respectively. The arithmetic mean was 0.083 microgram g-1 ash. The concentration of uranium in bone (ash) correlated with age, but not with sex; uranium participates in the bone calcification process.
