How many bananas do I need to eat to die of radiation?
A lethal dose of radiation is considered to be the one that will cause the death of 50% of an exposed population, within 30 days of having been exposed. This dose is in the range of 4 to 5 sieverts, received over a very short period.
The banana equivalent dose (BED) of radiation is 0.1 μSv, and in practice this is never lethal because the radioactive compound (potassium-40) from ingesting bananas is eliminated through urine. Even if this dose had been cumulative, you would need to be physically capable of ingesting 40000000 bananas in a very short amount of time.
Assuming that I was able to ingest this huge amount of bananas, in how many minutes should I eat them to die from radiation?
