Description |
The sediment samples have been collected from estuarine regions of Mindola and Purna of Gujarat State These samples are found to contain less than 3% of organic matter which scavenge and carry most of the activity of sup(226)Ra, etc., to the sediment floor The activities of sup(226) Ra are found to vary from 0.1 to 0.5 pCi/g, while sup(210) Pb activities lie in the range of 3 to 8 pCi/g These activities find their way into the organisms present in sea water and then into fish which is finally consumed by humans The sampling techniques, experimental procedures and the distribution of the isotopes of sup(226) Ra and sup(210) Pb in the estuarine regions and the concentration factors of sup(226) Ra in the region are detailed.
