| Abstract: | In a long-term study discontinuous extracorporeal blood irradiation (ECIB) was applied to a goat using a 500 Ci-137 Caesium source. Lymphocytes of the peripheral blood were examined by light and electron microscopy. After application of a transit dose of 466,500 rad the lymphocytes in the peripheral blood were found to be decreased from 6,900/microliter to 500/microliter, revealing a complete dissolution of the nuclei in electron microscopic preparations. Histological examinations showed a severe atrophy of the whole lymphatic tissue. |
