Title: Field study of Ra accumulation in trout with assessment of radiation dose to man

Abstract

The purpose of this study was to determine the concentrations of /sup 226/Ra in edible fish from surface ponds near an open pit U mine. Because one reclamation plan for the U mine proposed formation of an artificial lake in the open pit, potential radiation dose to man from ingestion of fish needed to be investigated. Trout were collected from four existing ponds which varied in mean /sup 226/Ra concentration from 12-33 pCi/l and in Ca concentration from 30-330 mg Ca/l. Radium and Ca accumulation in trout flesh, skin, fins and bone were measured. Geometric mean concentrations of /sup 226/Ra in trout flesh from four ponds ranged from 6.3-30 pCi/kg wet weight. The distribution of Ra in the trout body was similar to that of Ca. The calculated dose equivalent commitment to human endosteal tissue range from 0.2-2 mrem per fish consumed, depending on the assumed dietary and environmental parameters. Neglecting the consumption of trout skin underestimated the ingestion dose from /sup 226/Ra by a factor of 5-10. Estimated annual dose equivalent rates to human endosteal tissue ranged from 1.0-83 mrem/yr for an individual who consumed one fish per week for a 50-yr period. The dose to man from ingestionmore » of /sup 226/Ra in fish would not likely preclude the establishment of a recreational lake at this site.« less
