Abstract
For the estimation of internal radiation to human beings, the amounts of Mn, Fe, Cu, Zn, Co and Cs in 5 species of marine cephalopods were determined by atomic absorption spectrophotometry and neutron activation analysis, and then the concentration factors were calculated. The average amount and the concentration factor of the elements in the edible parts (mantle, arms and tentacles) of cephalopods are as follows: 0.14mg, 2×102 for Mn, 1.8mg, 2×102 for Fe, 2.0mg, 7×102 for Cu, 12.2mg, 1×103 for Zn, 5.3μg, 6×101 for Co and 3.4μg, 7 for Cs. The amounts of Fe, Co, Cu and Zn in the liver and the branchial heart were much higher than those in the edible parts, although those of Cs and Mn were almost the same. The Co content in the visceral organs of O. vulgaris showed extremely high value, particularly in the branchial heart.Keywords
