‘Ba contributed 4-202 of radioactivity at that
time. The radioactivity decreased extremely
rapidly, e.g. at about 6 months after the detonation, the activity in the urine was barely deAfter 8$ years, the levels of ‘Cs in
urine/2+hrs. were the same to that of normal
persons.
Radiochemical analysis of several organs from
the fatal case, which died on 23 September 1954,
showed that, comparing with the controls, radioactivity of these organs was clearly higher, although it was not extremely high.'”
Whole body counting was performed on three
persons 8§ years after the initial exposure. No
sixnificant difference was found between the
curves of the three irradiated persons and the
curve of the control.

Symptons and Sigus in the Early Stage
Soon after the initial exposure most of the
patients experienced anorexia, fatigue and lachrymation, etc.
These symptoms and their
changes are illustrated in Fig. 1.
The diseases occurred between 1955 and 1963
are listed in the following.
T- 3 eczema (1957-1960), pneumonia (1963)
K- + erosion of r. external ear (1962), impetigo (1963)
K- 8 r. pulmonary phthisis (1955)*
K-10
r. exsudative pleuritis (1959)*, Furunculosis (1960)
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 diflicule.
Shortly after the exposure, they
suffered 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.
