 Did you know...

Bananas

Bananas are radioactive.
Here’s a random fact about one of your favorite foods: Bananas contain potassium, and since potassium decays, that makes the yellow fruit slightly radioactive. But don’t worry—you’d need to eat ten million bananas in one sitting to die of banana-induced radiation poisoning.

Stomach Acid

Stomach acid is strong enough to dissolve stainless steel.
Your stomach digests food thanks to highly corrosive hydrochloric acid with a pH of 2 to 3. This acid also attacks your stomach lining, which protects itself by secreting an alkali bicarbonate solution. The lining still needs to be replaced continually, and it entirely renews itself every four days.

Helium

Helium changes our voice because of its density.
Helium is much less dense than oxygen. Typically, we breathe in nitrogen and oxygen. Since helium is less dense than oxygen, the sound of our voice travels faster through our vocal cords. Therefore, helium makes our voice sound weird because the sound is traveling over two times faster than usual.

Radiation

If you get exposed to radiation, you need to get naked.
One of the weirder yet essential nuclear energy facts: If you get exposed to nuclear substances, the best course of action is to remove all of your clothes. This will remove 90% of the radioactive substance you were exposed to.
