I'm not sure what you're saying. Are you saying that one needs to eat 50 kilogram of those daily to exceed the safe annual dose, or that if one eats 50 kilogram over a year, they'll have amassed more radiation from that single source than is considered safe? If the latter, is it safe expose yourself to more than [annual dose/365] in a short time? Because 50 kg/year is just 150 gram/day, and some people eat more than that in one sitting.
