Ceramics of multiple styles from five archaeological sites on Antigua were analyzed at the University of Missouri Research Reactor Center to obtain a better understanding of ceramic compositional variability within Antigua. Bulk chemical characterizations of pottery were determined by neutron activation analysis. Findings suggest that all of the ce...

The present study reports the first data on NORM distribution in soil and pottery samples collected from excavated sites of Erenda (Trench A1) and Bahiri (Trench YB1) located in East Medinipur, West Bengal, India. Collected potteries include grey-wares, red-wares, black-wares and black-red-wares. It was observed that 238U and 40K activities of the pottery samples are higher than that of the soil samples, which might be an indication of their different origin. 232Th activity is uniform along the depth and has similar distribution in both soil and pottery samples of Erenda and Bahiri.
