The recoveries of very low level 210Po in airborne dusts, in an electrochemical displacement treatment, were determined. Two methods were used here, the one is a direct method by the use of natural 210Po and the other is a tracer method. Both recoveries determined by two methods agreed well with each other.
The recoveries of 210Po in airborne dusts, at 10-12 and 10-13 Ci could be considered as being better than 90%. The values are similar to the ones at higher levels.
