北海道における日常食中の放射性セシウム(134Csおよび137Cs)量について調査を行った.札幌市およびその近郊に住む成人から提供を受けた1日分の食事(陰膳方式)を灰化して試料とした.測定にはGe半導体検出器を用いた.本調査における日常食中の放射性セシウムの最大値(平均値)は,2011年7月1.0 Bq/人・日(0.24 Bq/人・日),11月1.3 Bq/人・日(0.30 Bq/人・日),2012年2月3.9 Bq/人・日(1.0 Bq/人・日),そして7月0.34 Bq/人・日(0.12 Bq/人・日)であった.本調査における放射性セシウムの最大値3.9 Bq/人・日の食事を1年間摂取し続けたときの預託実効線量は0.022 mSv/年であった.

In order to determine both the distributional variation of heavy metals and the relationship between lead and essential metals in rats poisoned by lead, a study was undertaken using atomic absorption spectrophotometry.The cerebral lead concentration increased according to the amount of lead administered. The distribution patterns of lead in seven regions of the brain were significantly different between lead-treated animals and controls. In the latter, the differences in lead concentration among the individual regions were statistically significant, with the lowest levels reported for the cortex. In contrast, the cortex and hippocampus had the higher concentration in rats to which 45μg/g or 90μg/g of lead had been administered. Those given 180μg/g body weight showed uniform accumulations in all cerebral regions.Iron concentrations were highest in the hippocampus, while zinc and copper concentrations were distributed almost uniformly. No statistically signigicant loss of essential elements was recorded from the brains of lead-treated animals, but significant decreases of copper from the liver and of iron from the whole blood were found.
