Abstract

In recent years there has been growing international interest in the assessment of doses and risks from ionizing contaminants to organism. In this study The Environmental Risk from Ionizing Contaminants: Assessment and Management (ERICA) Tool was applied to estimate dose rates to Chanos chanos in marine ecosystems from Jakarta Bay exposed to 137Cs from Java sea environmental monitoring data. Data sets consisting of measured Concentration Ratio (CR) in different size of Chanos chanos and all default parameter provided by ERICA database. The uptake of 137Cs via seawater displayed a simple exponential kinetic model suggesting that the CR of 137Cs within Chanos chanos with a weight range of 2.46 x 10-3 - 9.86 x 10-3 kg at steady state period were between 10.66 - 3.98 L.kg-1 after 10 days of exposure. The depuration rate for 137Cs accumulated via seawater was slow, only 22.80 - 49.14% of 137Cs were absorbed in whole body of Chanos chanos. Using the CR from laboratory experiment, the total dose rates of 137Cs to Chanos chanos were all below the threshold 10 µGy.h-1 . Chanos chanos dose rate in the present study were 2.26 x 10-7 – 4.55 x 10-7 µGy.h-1 .
