  1. Radioactive contamination of cistern waters along the Croatian coast of the Adriatic Sea by 90Sr.

    Article - En anglais

    Measurements of radioactive contamination of water samples from cisterns collecting rainwater containing fission products from roofs and other surfaces have been carried out along the Croatian coast of the Adriatic sea since 1968.

    An exponential decline of radioactivity followed the nuclear moratorium.

    After the nuclear accident at Chernobyl, higher levels of 137Cs and 90Sr were detected again, with cistern waters being the only environmental samples in Croatia in which elevated 90Sr activities persisted for several years.

    For the pre-Chernobyl period, the observed mean residence time of 90 Sr in cistern waters, estimated to be 6.2 ± 1.9 y, was similar to that calculated for fallout.

    Contrary, for the post-Chernobyl time, observed 90Sr mean residence time was calculated to be considerably shorter, reflecting the tropospheric mean residence time.

    The annual dose for the critical adult population received from 90Sr and 137Cs by drinking cistern water was estimated to be very small, in the 1990's less than few muSv y-1.
