Title

Distribution of 137Cs Radionuclide in Industrial Wastes Effluents of Gresik, East Java, Indonesia Muslim Muslim; H. Suseno; F. Rafsani
Atom Indonesia Vol 41, No 1 (2015): April 2015
Publisher : PPIKSN-BATAN

The distribution of anthropogenic radionuclides 137Cs was measured from industrial waste effluent of Gresik to Gresik Sea in east Java, Indonesia. The activity of 37Cs detected at all stations was much lower than in northeast Japan both before and after NPP Fukushima accident. This indicated that in Gresik industrials waste did not consist of 137Cs. The lowest activity 137Cs occurred at the station nearest to the industrial waste effluent that contained some particle ions that were able to scavenge 137Cs and then precipate this radionuclide. Furthermore, the greatest 137Cs occured at the station that has high current speeds that stirred up sediment to release 137Cs in seawater as a secondary source. The lowest salinity did not effect on the activity of 137Cs even though the lowest salinity and activity 137Cs occured at the same station.Received: 04 October 2014; Revised: 09 March 2015; Accepted 23 March 2015

Upwelling is an important event in the sea for it makes the area to become more productive. The objective of this study is to determine the distribution of radium-226 as radiotoxic in the upwelling area in the summer season. Measurements of the horizontal and vertical activities of 226Ra in the Ulsan, Gampo and Pohang waters were conducted in June, August 1999 and June 2000 when the upwelling event was expected to occur. Water temperature, salinity and dissolved oxygen (DO) were also measured concurrently. The thermocline layer or the layer where the temperature decreased drastically occurred at a depth between 30 m to 100 m for samples dated June 1999 and 30 m to more than 100 m for samples dated August 1999 and June 2000. The salinity decreased with depth but the DO concentration increased in this layer. The condition affected the vertical distribution of 226Ra in the study area, where the 226Ra activities showed to be relatively homogeneous vertically in each station. This indicates that the upwelling which occurred in the study area was capable to distribute the 226Ra activities from the bottom to the surface. Thus, the 226Ra distribution at that time did not increase with depth, opposite to what usually occurs in the ocean at normal condition. The 226Ra activities also did not decrease after elapsed time of one year, in fact, it increased. However, horizontally the 226Ra activities decreased with increasing distance from the coastal zone. Based on these results, it can be concluded that the upwelling event in the Ulsan, Gampo and Pohang was effective for increasing the 226Ra activities and was capable to create homogeneous 226Ra activities from the bottom to the surface in the water column, and the source of 226Ra was likely to originate from outside area (i.e. coastal zone) and bottom area.Received: 25 March 2009; Revised: 24 August 2009; Accepted: 30 September 2009

Present Status of Marine Radioecology in Jakarta Bay H. Suseno; B Budiawan; M Muslim; M. Makmur; M. N. Yahya

Operation of nuclear facilities such as research reactor and it’s supporting installation in Serpong Nuclear Area may release controlled radionuclides to Cisadane River and then it would flow to Jakarta Bay. There are limited marine radioecology studies or radionuclides monitoring at Jakarta Bay. Therefore monitoring of 239/240Pu and 137Cs was carried out from Tanjung Pasir to Tanjung Kerawang. The ERICA Assessment Tool was used to evaluate radiological risk in the marine environment of Jakarta Bay area. The 137Cs concentration in sea water and sea sediments were in range of 0.17 – 1.17 Bq.m-3 and 0.34 – 1.21 Bq.kg-1, respectively. Moreover, result of 239/240Pu measurement showed that concentration at sea water and sea sediment were range from < MDA – 0.53 mBq.m-3 and 2.64 – 55.70 mBq.kg-1 respectively. The results of risk analysis were indicated that all the total dose rates per organism were millions time lower than the screening rate (10 mGy.h-1).

Behavior of 137Cs Activity in the Sayung Waters, Demak, Indonesia M Muslim; H. Suseno; M.J. Pratiwi

The behavior of anthropogenic radionuclide 137Cs in the water and sediment has been examined with regard to particle size, organic sediment, and other physical conditions in the Sayung estuarine waters of Demak. Previously, this estuary was used as shrimp culture brackish water ponds that were affected by serious erosion and intrusion. Furthermore, this regency rapidly industrialized over the last three decades. The activities of 137Cs in the six stations in water and sediment were in the 0.0116-0.4509 mBq/L and 0.3747-1.2442 Bq/kg ranges with mean activities of 0.2278 mBq/L and 0.8594 Bq/kg, respectively, depending on the prevailing physicochemical regime at the sampling station. The highest activities of aqueous 137Cs occurred in station 2 but the highest in sediment occurred in station 6 located closed to the main land of Sayung. Fast current effectively diluted 137Cs as a conservative radionuclide in seawater, thus the activity of 137Cs in seawater decreased when the current speed increased. This effect was caused in part by industrial pollutants that adsorbed 137Cs and precipitated onto the surface sediment. Organic matters and clay materials in sediment were not significantly effective at binding 137Cs in Sayung waters in the industrial coastal area, but the correlation increased in open areas separated by a breakwater (second group stations) and the location further from the beach or in open sea. This indicates that industrial pollutants are more effective at binding 137Cs than organic matters and clay materials. Fine grain size sediment is also more ineffective at binding 137Cs; it may be caused by the sediment's high total organic matter content.Received: 25 April 2016; Revised: 27 October 2016; Accepted: 8 November 2016
