Goats and Swine were exposed at varying distances
to the bursts at Operation Crossroads in order to study
the hemorrhagic effects of bomb radiations. It was
considered that all pathologic phenomena observed were
the result of {gamma} radiation, either at the time of
the explosion or from {gamma} emission of residual

KEYWORD(S)

radiation. In general, the hemorrhagic syndrome could be
divided into three stages: that of increased capillary
fragility; increased capillary fragility plus a
progressive thrombopenia; increased capillary fragility,
thrombopenia, and a blood coagulation defect. The blood
coagulation defect was observed only in fatally
irradiated animals in which terminal bacterial invasion
was also prominent. A circulating anticoagulant was
shown to be present 10d to 12d after exposure, and it
could be neutralized in vitro by toluidine blue and to a
lesser extent by thrombin and thromboplastin. Evidence
was presented suggesting that fibrinolysins may have
been activated or increased in concentration.
