Re: uranium in urine analysis
Radsafers,
I can understand Franz's concern. You are talking uranium intake in water
of up to 9 mg/l, and there is bound to be further concentration in the body
fluids. If I am not mistaken, 3 mg/l was regarded as a maximum
sustainable uranium excretion rate in urine, whereas 10 mg/l would lead to
rapid kidney damage and failure. The lethal body burden of dissolved
uranium is supposedly 1 mg/kg of body mass (70 - 100 mg total for an
adult). That 'water' is poison.

Did I misunderstand or miss something? Wasn't EPA proposing something like
10 or 20 micrograms uranium per liter as a limit in drinking water? Are
those people to be used as guinea pigs instead of cutting off their water
supply at once and supplying them with clean water or installing devices
for
removal of uranium?
