“The common contaminated foods which would be the major source of Sr-90 might be classified into five grades- A, B, C, D, and E... The A food would be restricted to children and to pregnant women. The B food would be a high-priced food available to everybody. The C food would be a low priced food also available to everybody. Finally, the D food would be restricted to people over age forty or fifty... Most of these people would die of other causes before they got cancer.”
