No, Bjorn C, you're not lost. However, the 4th edition of Eisenbud (1997)
p. 147 cites another ref. for the activity (Penna Franca et al. Health
Phys. 14, 95-99, 1968). PF has a value of 10 - 260 Bq (273 - 7100 pCi) per
kg for the activity of Brazil nuts. 

I, too, link an earlier aflatoxin discussion in the media to these nuts.
