Abstract
In-situ pre-concentration technique using MnO2 filter cartridge adapted for radium isotopes measurement in seawater. Natural variability was observed and data subjected to statistical analysis. Seawater and sediment concentration was observed lognormal and evaluated geometric mean for 226Ra was 2.9 Bqm−3 and 1.7 Bqm−3 and 228Ra was 5.8 Bqm−3 and 4.6 Bqm−3 in seawater along west and east coast respectively. For sediment 226Ra GM was 12.5 Bqkg−1 and 30.0 Bqkg−1 and 228Ra was 21.7 Bqkg−1 and 62.0 Bqkg−1 along west and east coast respectively. Estimated environmental increment could be used as screening levels for assessing impact on the environment.
