[00:00:00]The banana you ate today is radioactive.

[00:00:03]Don't panic. You'd need to eat 10 million at once to actually get hurt.

[00:00:08]Bananas are loaded with potassium.

[00:00:11]And potassium naturally contains a radioactive isotope called potassium 40.

[00:00:16]Each banana emits about 15 becquerels of radiation.

[00:00:21]Scientists [music] literally invented a unit called banana equivalent dose to help people understand radiation.

[00:00:27]Nuclear leak?

[00:00:29]Equals roughly this many bananas.

[00:00:32]It's not just bananas, Brazil nuts, potatoes, even your body is radioactive.

[00:00:38]Potassium 40 in you decays 4,000 times per second.

[00:00:42]You're a walking mini reactor.

[00:00:45]Someone once drove a truckload of bananas through customs and triggered the radiation detector.

[00:00:50]Security was like, is this fruit or a warhead?

[00:00:54]So next time someone asks if you've been exposed to radiation, say, yes, every breakfast.

[00:01:00]But honestly, your sleep schedule is way more dangerous.
