A closer look

Bananas contain potassium-40, making them legitimately radioactive enough to trigger false alarms at nuclear checkpoints if you pack enough of them, though you would need to eat about ten million bananas at once to die from radiation poisoning, which is a physical impossibility that completely ruins any supervillain plot involving weaponized fruit; truckloads of bananas occasionally cause panic at US ports when their combined radioactive emissions set off security sensors designed to detect smuggled nuclear weapons, making it incredibly funny that homeland security has to waste time distinguishing between a genuine threat to national safety and a shipment of smoothie ingredients, meaning that while a radioactive spider might give you superpowers, a radioactive banana just gives you a mild dose of potassium and a reminder that the universe is inherently absurd
