Studies conducted over a 3-year period have shown that levels of strontium-90 and iodine-131 in milk can be moderated by optimal fertilization of the land. In controlled experiments, milk from cows grazing on abundant, well-fertilized pastures contained 50 percent or less of these radionuclides than did milk from cows grazing on unfertilized pastures on the same farm. A mechanism of dilution of the fission-product contamination in the larger volume of faster growing fertilized forage was shown to account for the differences in the milk. The findings suggest one possible means of controlling fission-product contamination in milk, if such control measures should be necessary. The results indicate that the high levels of strontium-90 in the St. Louis raw milk samples may have been due more to marginal fertilization of the farms than to uneven deposition of fallout.
