The risk of dying due to cancer is estimated to increase by 1 in
a million if a person eiher absorbs 10-4 Sv of ionizing
radiation or smokes 1.4 cigarettes.
a) what is the dose equivalent of smoking half of a
cigarette?
b) bananas are rich in potassium (including the radioactive
potassium-40). Because of this, an unusual measure has been
suggested — the “banana equivalent dose.” A dose of 9.8 x
10-8 Sv could be gained by eating one banana. How many
bananas would cause the same dose as received by smoking half a
cigarette?
