| description | The source of radioactivity in the marine environment, mainly come from global fall out and nuclear power plant accidental releases. Among the major long-lived radionuclides, 137Cs is one of the most important. This radionuclides was transported to the marine area undergo several complex natural processes that depending on, particles quantity, marine circulation and suspended on sediment. The main purpose of this experiment are to determine activity of 137Cs in sea water and sediment. The other purpose is to know 137Cs distribution in Yogyakarta coastal area. The result found that activity of 137Cs in water is 0.0615-0.4908 mBq/L and in sea sediment is 0.219-1.312 Bq/kg. These activities are comparable with activity in sediment of Bangka that the source is from global fall out. Data of 137Cs activity againts organic matter give informations that at depth from surface to 20 cm are an acumulation of 137Cs and after 20 cm activity of 137Cs is decreasing because of organic matter is increasing. This experiment data show that Yogyakarta coastal area was not yet contaminated by nuclear reactor accident in Fukushima, Japan. |
