>>14161615The dose from one banana is roughly 0.1 microsieverts. With a dose of 4-5 sieverts, you have a 50% chance of death. A dose of 10 sieverts will surely kill you.
To get a dose of 10 sieverts, you need 1,000,000,000 bananas. Assuming these are large bananas that weigh 140g each, that works out to 140,000 tonnes.
