1, The Jepanese data showed that their highest dose rate reading
was only fifteen tines their background readings as recerded during the
early part of their vayage.

The beckground radiation level (0,060.07 ur/hr bete-gama) in
Raban] was sabstantial, comparatively,
No explanation for this is
offered,
3.
The relatively low cumilative gemma readings recorded on the
SATUMA deeineter do not necessarily indicate a true dose.
It is entirely
probable that radiation leakage of the instrument secounted for a large
portion of the recorded dese.
de ‘The redistion dese rates on beth the TAKUYO and SATUMA at the
time of nenitering were found te be substantially identical.
The decon=
tamination moawures carried out om the TAXUTO were effective in redusing
the radiation level to essentiallybeckground.
