Strontium in Diet [PDF]

open access: yesBMJ, 1958
Measurements have been made of the stalale strontium and strontium 90 content of various articles in diet in four regions of Britain in 1957 and estimates of the content of typical adult diets deduced. The mean ratios of strontium to calcium are: stable strontium/calcium == 1200 mu g/g, and strontium 90/calcium = 5.5 mu mu c/g.
