  • Title: Vertical distribution of (241)Pu in the southern Baltic Sea sediments.
    Author: Strumińska-Parulska DI.
    Journal: Mar Pollut Bull; 2014 Dec 15; 89(1-2):12-15. PubMed ID: 25455816.
    Abstract:
    The vertical distribution of plutonium (241)Pu in marine sediments can assist in determining the deposition history and sedimentation process of analyzed regions. In addition, (241)Pu/(239+240)Pu activity ratio could be used as a sensitive fingerprint for radioactive source identification. The present preliminary studies on vertical distribution of (241)Pu in sediments from four regions of the southern Baltic Sea are presented. The distribution of (241)Pu was not uniform and depended on sediment geomorphology and depth as well as location. The highest concentrations of plutonium were found in the surface layers of all analyzed sediments and originated from the Chernobyl accident.
