How much radiation does a banana emit?

Bananas emit a small amount of radiation due to the presence of naturally occurring radioactive potassium-40. Specifically, the average banana emits about 0.1 microsievert (µSv) of radiation. This level of radiation exposure is extremely low, considering that the average person is exposed to around 2,000 µSv from natural background radiation sources every year. Therefore, consuming bananas or being around them poses no significant risk in terms of radiation exposure and is considered completely safe.
