Estimated Potassium Content in Hanford Workers
Potassium content in male and female workers at the Department of Energy Hanford Site was estimated based on measurements made in 2002 of 40K activity in the body. A coaxial germanium detection system was used for the measurements. The activity in female workers ranged from 2.1 to 4.1 kBq with an average of 3.1 ± 0.02 kBq. Total body potassium (TBK) content in female workers averaged 96 ± 0.3 g. The activity in male workers ranged from 2.8 to 6.6 kBq with an average of 4.3 ± 0.01 kBq and the average TBK was 136 ± 0.3 g. The average potassium concentration decreased with age in both males and females. The average potassium content and potassium concentrations for both males and females were less than the corresponding reference values. Potassium concentrations were inversely correlated with body-build index, body-mass index, and body weight for both males and females.
