6. The examined fishermen wereclassified in 3 groups according to the
degree of the injuries indicated by the minimum values of neutrophils
shown shortly after the exposure. It was found that the mean values of stable
and of unstable cells were higher in proportion to the extent of the initial
damage. Minimum values of neutrophils roughly corresponded to the estimat-

As a generative tissue, spermatogenesis has many similarities with hematopoiesis. Therefore, the changes of number of spermatozoa is described for
reference. The number of spermatozoa decreased, and minimum numbers were
obtained in 16 cases about 8 monthsafter the exposure.
