Bananas have 3.5 pCi/g, or 525 pCi per 150 gram banana, enough to alarm a radiation monitor. One per day would give you 36 microSieverts per year.
In America from all sources we get about 6,200 microSieverts per year.

Salmon has 20.0 pCi/g, nearly 6 times as much. A 150 gram piece of salmon will thus emit 3,000 pCi of radiation, a little over 200 microSieverts per year if you ate that much everyday.
Naturally!
