Study of soil-to-plant transfer factors (TFs) of Ra, Th, and K on plants cultivated on ex-tin mining land in Bangka Belitung, Indonesia.

Soil-to-plant transfer factors (TFs) are of fundamental importance in measuring the environmental impact due to the presence of radioactivity in soil and agricultural crops. The present study thus to measure soil-to-plant TFs of Ra, Th, and K on horticultural plants cultivated on ex-tin mining land in Bangka Belitung islands. There were 21 samples of 15 species and 13 families from 17 locations comprising four vegetables species, five fruits species, three staple foods species, and three others.
