Abstract

A study on the contamination levels and distribution of plutonium in gastropods collected in Palomares (south-east Spain) has been performed. This region is partially contaminated with actinides following the nuclear accident occurred in 1966. The existence of plutonium in gastropods (Helix albicans and Theba pisana) along with their great gastronomic interest in the area reinforces the concern in studying the incorporation of these radioelements into a trophic level of the alimentary chain.

In this work, plutonium concentration levels have been determined in the excrements, washing waters, flesh and shell of different types of gastropods collected in the Palomares most contaminated area. Plutonium analyses have been carried out following normalized procedures for the determination of this radionuclide.

The results show the distribution of plutonium in washing and boiling water, excrements, soft tissues and shell of the snails. In addition, it has been estimated that the consumption of one kilogram of snails collected in the most contaminated area of Palomares could contribute up to 1/3 of the effective dose (due to ingestion) to the inhabitants of the area.
