CALCULATION OF RADIOACTIVE IODINE CONCENTRATIONS IN MILK AND HUMAN THYROID AS A RESULT OF NUCLEAR EXPLOSIONS

摘要

The production and distribution of radioactive iodine by nuclear explosions is discussed. Equations and graphs are presented by which the levels of I131 and I133 corresponding to the Federal Radiation Council (F. R. C. ) guide can be determined. The fallout level, intake by cows, concentration in milk, and content of the human thyroid are considered.nIt is concluded that the maximum concentration in milk as the result ofna single event which corresponds to F. R. C. guide is approximately 2800 picocuries (pCi) per liter.
