I propose a larger unit of measure: the Chernobyl Sheep Equivalent Dose. This is based on a 50kg sheep at the upper allowable limit of 1000 Becquerels per kg. http://en.wikipedia.org/wiki/Chernobyl_disaster_effects#Food...

Converting our Banana Equivalent Dose of 520 picocuries. 1 Bq (Becquerel) = one radioactive decay per second. 1 Ci (Curie) = 3.7 * 10^10 Bq. 520 picocuries = 520 * 10^-12 Ci = 19.2 Bq. Our 50kg sheep = 50 * 1000 = 50000 Bq.

1 Chernobyl Sheep Equivalent Dose = 2600 Banana Equivalent Doses.

Hopefully I got my sums right.
