Radiometric measures revealed the presence of a Co-60 source,
with a hot–spot of gamma dose rate of 600 mSv/h at contact with one wall of the
container, about 40 mSv/h at one meter and 100 mSv/h at 25 meters from the
container wall. A rough estimation gave the source activity ranging from 150 to
200 GBq.
The effective dose received by each person in the harbor area
has been estimated to be less than 1 milliSievert. As a precautionary measure
and with the aim to reassure the people, about thirty-five workers were
identified and subjected to medical examination and some clinical analysis.
According
to national legislative provision, the prefecture is also managing the
activities aimed at preparing for the safe return of the radioactive material to
the country of origin, in compliance with international regulations on the transport
of radioactive materials.
