From the brains behind brains on, this is the Moment of Um.

Moment of Um comes to you from APM Studios. I'm nervous Nelly.

Um.

You've caught me at a really bad time.

You see, I'm supposed to go over to my friend's house for the first time ever, and I'm feeling pretty nervous.

What if I have to go to the bathroom, and I'm too shy to ask where it is?

Or what if we have peanut butter and jelly sandwiches for lunch?

But she only has orange marmalade.

All those little chunks of orange peel in there.

Or, what if I accidentally bump into her fish tank and her goldfish jumps, and I try to catch it, but it's too slippery.

The world can be a scary, stressful place, and there's even stuff out there that I'm not sure if I should be nervous about.

Like the other day, I heard that bananas are radioactive. Is that true?

And if so, what does it even mean?

My friend Zoe and Allie were wondering the same thing.

Hi, I'm Zoe.

And I'm Allie. And we live in Northern Washington.

And we recently heard that bananas are radioactive.

Is this true?

Bananas are indeed radioactive.

I'm Robert Chin.

I'm a radiation oncologist at UCLA.

So we treat cancer patients with high-energy radiation beams as that tumors out of people.
