Abstract

Samples of coastal marine sediments of the East Coast of India were leached with a saturated solution of ammonium carbonate for the extraction of uranium from the sediment particle surface without attacking the mineral core of the particles. All the sediment samples were found to exhibit a234U/238U activity ratio in the range of 1.07 to 1.14. On removal of surface organic matter, the234U/238U activity ratio is close to 1.00, indicating that the anomaly between238U and234U exists only on the labile surface layer. However, no such variations are observed in235U/238U activity ratios. These ratios are close to 0.045 which is the same as that of natural uranium.
