Abstract
MILK and cereals provide the major part of the calcium, and consequently of the strontium-90, in the Finnish diet. According to the statistics of the Food and Agriculture Organization1, the contribution of cereals to the calcium supply is calculated at 6 per cent; this is much less than the corresponding figure for milk, 87 per cent. However, the ratio of strontium-90 to calcium is so much greater in cereals than in milk that the cereals approach milk in importance as a supplier of radio-strontium, especially in a country like Finland, where no calcium is added to cereals.
