Abstract
The paper presents the results of the dissolution characteristics of 226Ra from phosphogypsum, a by-product from phosphate fertilizer industries. Leachability of 226Ra in distilled water and rainwater have been examined under different leaching conditions such as contact time, solid:liquid ratio and simulating natural conditions. The concentration of 226Ra activity in the leachates ranged from 0.07 to 0.53 Bq l(-1). Study indicated that leaching of radium may be slow in field conditions near the phosphogypsum stock piles.Entities:
