Abstract

NORM (Naturally Occurring Radioactive Material) is a radionuclide element that naturally already exists in the earth. Its concentration can be increased by industrial activities, such as coal-fired power plant (CFPP). Coal-fired power plant activities produce fly ash and bottom ash which will be carried away by the wind and then can enter the CFPP environment, one of which is marine waters and can affect the existence of marine biota. The determination of the radiation dose rate is essential in assessing the risk of radionuclide exposure to the marine environment. This study aims to determine and evaluate the total dose rate of 210Po to marine biota taken from the Karangsari fish market with catchment areas around the waters of CFPP Tanjung Awar – Awar, Tuban, East Java. This research was conducted in April 2021 in the waters of CFPP Tanjung Awar – Awar.  210Po measurement activity was carried out using alpha ray spectrometry at the Marine Radioecology Laboratory of PTKMR-BATAN, then the radiation dose rate was calculated using the ERICA Tool software. The value of the total radiation dose of 210Po on marine biota ranges from 2.70E-1 µGy.hr-1 to 39.70E+0 µGy.hr-1. The radiation dose of 210Po on marine biota measured in the waters of CFPP, has a lower value range than the research result carried out in other countries. Based on the Erica Tools software analysis, the total radiation dose measured on marine organisms in the waters of CFPP Tanjung Awar – Awar, does not give a negatively impact to the marine ecosystems and the sustainability of marine organisms in the study area.

Abstract

Fly ash and bottom ash from coal combustion can contain natural radionuclides with a certain concentration. The release of fly ash into the environment can potentially increase the concentration of natural radionuclides in the surrounding environment, including marine waters. This study aimed to determine the activity of natural radionuclides in seabed sediments and the radiological impact on marine organisms related to Tanjung Awar-Awar Coal-Fired Power Plant activities in Tuban. The sampling techniques were carried out by the purposive sampling method. The concentration measurement of natural radionuclide activity was carried out using HPGe detector gamma-ray spectrometry at marine radioecology laboratory of National Nuclear Energy Agency. The detected concentration of natural radionuclide activity was 40K ranging from 159.18 to 365.88 Bq.Kg-1, 228Ac ranging from 14.47 to 28.05 Bq.Kg-1, and 226Ra ranging from 15.00 to 67.65 Bq.Kg-1. By using the ERICA Assessment Tool Tier 2 program, the results of the analysis showed that there was no impact of 226Ra radiation on marine organisms at the research site because the total radiation dose rate (external + internal) of 226Ra on marine biota was lower than the screening level of 10 μGy / h. Thus, it will not harm marine ecosystems and the sustainability of marine organisms in the waters of Tanjung Awar-Awar Coal-Fired Power Plant, Tuban.

Abstract

The East Coast of Johor in Malaysia is a strategic area as a candidate site for nuclear power plants. Its location is near coastal area and is therefore convenient to use seawater as a source of cooling for power plants. This makes the East Malaysia waters, and their surroundings stand a high risk of direct radioactive contamination, especially in event of an accident. Pu is a non-conservative or reactive radionuclide that easily settles with particles and has high radiotoxicity and radiochemistry, making it very dangerous. The purpose of this study was to determine the distribution patterns of 239/240Pu releases in the waters of East Malaysia and the surrounding waters. To determine the affected areas due to 239/240Pu pollution using MIKE flow flexible mesh module and particle tracking module. The magnitude of 239/240Pu used in this model is based on the disaster in Fukushima Daiichi in 2011. This research can be used as a mitigation of 239/240Pu pollution when a nuclear reactor disaster occurs in the area around Indonesia's territorial border. Discharge of 239/240Pu was simulated during the west and east monsoons season which result in the distribution pattern following the seasonal flow pattern. During the west monsoon, the dispersion speed of 239/240Pu is four times faster than the east monsoon. The 239/240Pu distribution is predominantly towards the south, however, the contaminated area was only occurred on the coast of Johor and does not extend to the waters of Indonesia.
