Removal of Radioactive Caesium Accumulated in Fish Muscle by Washing in the Process of Surimi-Based Productions

Abstract

Radioactivities of several tissues of Pacific cod, nibe croaker, and white croaker captured around Fukushima were estimated with an imaging plate system. There were relatively high radioactivities in muscle. Effects of washing on residual Cs radioactivities in fish meat were estimated. Three-times washing with 0.1% NaCl solution was effective for the removal of radiocaesium from contaminated fish meat. Homogenization of meat was also effective for the removal of radiocaesium.
