super(210)Po Concentration in Perna Perna Mussels: Looking for Radiation Effects

super(210)Po concentration in Perna perna mussels is estimated. After one year of monthly sampling, no clear correlation is observed between super(210)Po concentration and mussel age and weight. A mean super(210)Po concentration of 155 Bq kg super(-1) wet weight basis, is found and this is comparable with data reported in the literature. Comparable results are obtained by changing the experiment methodology from seeding and sampling monthly during a whole year and a single sampling involving individuals of different sizes, 155.6 plus or minus 7.9 Bq kg super(-1) and 165 plus or minus 8 Bq kg super(-1), respectively. May be the higher frequency of micronuclei and DNA breaks observed in younger and/or smaller mussels can be related to other environmental factors different from the radiation derived from super(210)Po.
