Study of radioactivity among te Bulgarian Black Sea coastal zone - results from the NIMH monitoring program

Abstract

In the frame of the NIMH at BAS investigations of the Black sea radioactivity were initiated in 1978 with a development of a monitoring campaign. Samples of sea waters, sediments and algae were collected from several sampling sites along the coastal zone and measured by gamma-spectrometry. Results on gamma-emitting radio-nuclide's measurements in the Black sea coastal waters were published in the 80's. After the Chernobyl accident during the period between 1986-1989 seasonal-fields sampling campaigns were organised and radioactivity of algae and bottom sediments was estimated. Harmonized sampling strategies, analytical procedures and related data information exchange for radioactivity of seawater, sediment and biota in coastal areas of Black Sea countries were developed under the IAEA TCP Black Sea Project. The present work reports results of the monitoring programme of the NIMH of Bulgaria developed in the frame of the IAEA projects for the Black Sea basin. From 1993 to 2005 regular seasonal sampling was performed in 5 sampling sites along the Bulgarian Black Sea shore. Results of the dissolved '1'3'7Cs concentrations in sea water, sand, algae, and fish samples are discussed. The data for the different radio-isotopes measured in algae, fish and sea sediment samples are given in comparison with other  More>>
