Low-risk group – population risks
20 µg/kg standard
- (19 ng x 0.013)/60 kg bw = 0.0041 cancers per year per 100 000 people (range 0.0006 - 0.01)
10 µg/kg standard
- (18 ng x 0.013)/60 kg bw = 0.0039 cancers per year per 100 000 people (range 0.0006 - 0.01)
Reducing the hypothetical standard from 20 to 10 µg/kg yields a reduction in estimated population risk by 2 cancers per year per billion people
