The radioactivity decreased extremely rapidly, ¢.g. at about 6 monthsafter the detonation, the activity in the urine was barely detectable. After 84 years, the levels of '’Cs in rymation, etc. These symptoms and changes areillustrated in Fig. 1. their The diseases occurred between 1955 and 1963 are listed in the following. T- 3 K- + eczema (1957-1960), pneumonia (1963) erosion of r. external ear (1962), im- persons.

No significant difference was found between the curves of the three irradiated persons and the curve of the control. B. Clinical Observations 1. Symptoms and Signs K-16 acute appendicitis (1957) 2. Skin Lesions Skin lesions occurred due to beta radiation. An estimate of the radiation dose to the skin was w:licult. Shortly after the exposure, they suffeccd from erythema which was followed by edema, vesicle, erosion, ulceration or necrosis. * These were diagnosed by Dr. Kumatori. The others were due to complaints of the patients.
