CONTAMINATION OF FOODS BY RADIO-
Seibutsugaky 36, 249-52 (1955).
The radioactivities of various vegetable foods contami- |
nated by radioactive rains in May, 1954, in the
Kagoshima Area were detected. Tea showed especially
high radioactivities which could be extracted with hot
water. Radioactive Nb, Zr, Hf, Ce, Y, Pr, and La were
detected in the hot water extractions of tea by ionexghange chromatography. The partial contribution of
O in these radioactive vegetables was critically
exanined.

THE BIOLOGICAL INFLUENCE OF ASH FROM RADIOACTIVE FISH.
Igaku to Seibutsugaku 35, 57-9 (1955).
Bones of a radioacti.e fish were ashed, extracted with
10 per cent HCl, and the extraction was neutralized
with 10 per cent NaOH to give a white precipitate
suspended in Ho0. The suspansion was fed to rabbits.
Most of the radioactivity was excreted in the feces, a
small portion was retained in the cecum. Internal radioactivity was highest in the bones.

RADIOACTIVITY OF FISH II.
JgakytoSeibutsugaky 3,
Various tissues of fish captured east of Formosa after the
Bikini H-Bomb experiment had radioactivities (detected on
-May 27, 1954) in counts/min/ash from 5 g. fresh tissues:
blood 214, eyeball 49, heart muscle 111, white muscle ll,
red muscle (chiai) 123, bone 46, skin 28, pancreas-131,
liver 522, stomach muscle 106,
matozoa 47, and spleen 504%.

High radioactivities in blood
and blood synthesizing organs (liver and spleen) were
emphasized.
The radioactivity in the blood had a half-
life of 34-35 days and the maximum energy of B-ray of
