I'm bored, Kurumi.

I built the reactor. I boiled the water. I made the electricity.

But if fusion works, electricity becomes free. "Too cheap to meter."

If energy is free, my nuclear empire is worthless. It's a one-trick pony!

You think Nuclear is just heat and boiling water?

Shez, look at this paper. It has to be exactly 0.1mm thick. If it varies by a micron, the printer jams.

How do they measure it moving at 60 mph without touching

Lasers? Cameras? Magic?

We measure with **Beta Particles**.

Inside that box is Krypton-85. It shoots electrons at the paper.

If the paper is thin, more light gets through.

If the paper is thick, less light gets through.

We measure the "brightness" on the other side. That tells us the thickness to the atom.

So... it's a nuclear ruler?

It's a **Nucleonic Gauge**.

90% of the paper, plastic, and steel sheet in the world is measured this way.

Lasers get confused by dust or color. Radiation cuts through. It sees **Mass**.

What about this? Is there a nuke here too?

Of course. How do they know the can is full before they seal it? You can't see inside aluminum.

**Gamma Switch**.

A source (Americium-241) shoots Gamma rays through the can.

This mechanism checks 2,000 cans a minute. Your Diet Coke is quality-checked by a nuclear reactor.

Okay, so it's a sensor. That's cool.

But sensors are cheap. I want **High Value**.

I want to save lives. Can nuclear do that? Or does it just give people cancer?

Come with me. To the Hospital.

No no no. Are you really trying to give me cancer?

I know this! X-Rays! CT Scans!

But X-Ray machines use electricity to make radiation. That's not "Nuclear." That's "Electric."

Correct. X-Rays show **Anatomy**. Broken bones. Structure.

But what if you want to see the *biology* happening? The metabolism?

We don't shine radiation *at* the patient.

We put the radiation *inside* the patient.

INSIDE?! Are you insane?!

You told me about the Radium Girls! Their jaws fell off because they ate the paint!

Now you want to inject that stuff directly into my veins? That's suicide!

The Radium Girls died because Radium is a Squatter.

It mimics Calcium. It moves into your bones and stays there for 1,600 years, firing Alpha bullets.

This? This is Technetium-99m. It's a Tourist.

Medical isotopes have a Short Half-Life. Technetium decays in 6 hours.

By tomorrow morning, it's gone. It stops being radioactive.

And more importantly, we leverage **Biological Half-Life**.

We attach the isotope to a molecule your body wants to get rid of. You don't store it in your bones. You Pee It Out.

So... it flows through me, takes a selfie, and leaves?

Exactly. And it emits Gammas (Lasers), not Alphas (Bowling Balls).

The Gammas fly out of your body to the camera. They don't get stuck inside shredding your DNA.

Okay. The Tourist (Technetium-99m) and The Squatter (Radium). I get it.

Now, let's look at the Spy. To find cancer, we need a molecule that cancer loves.

What does cancer love?

Sugar.

We can't see the party from the outside.

So we give a glowing GPS tracker to a pizza delivery guy (The Tracer).

Cancer cells have a hyper-active metabolism. They eat Glucose 10x faster than normal cells.

We take a Sugar molecule and attach Fluorine-18 (The tracker).

This is FDG.

The tumor eats the sugar. It concentrates the radiation.

The tumor lights up like a neon sign.

Whoa. It's right there.

That's a PET Scan (Positron Emission Tomography).

X-Rays show you the structure (The House).

Nuclear Medicine shows you the activity (The Party). We see the hunger before the tumor is even big enough to see on X-Ray.

That's amazing. We found it.

But... can we kill it? Or do we just watch it glow?

Let's talk about the Radium Girls again.

Them getting infected by the long half-life of radium?

No, we talk about the Alpha Particle this time.

Its deadly if it hits bone marrow. But what if we tell it *where* to go?

We take an Antibodyâ€”a protein that hunts cancer cells.

We weld an **Actinium-225** atom to its back.

The drone hunts the cancer cell. It latches on.

*BOOM.* It releases the Alpha particle.

The Alpha particle only travels 3 cells deep.

It kills the target and *nothing else*.

This is a precision missile that kills the dictator and spares the civilians.

What!? We can cure cancer with nuclear waste?

Actinium-225 is a byproduct of decay chains.

We turned a so called "poison" into the cure. This is **Theranostics**.

Wow, I never realized how nuclear can be used in medicine.

But what about heavy industry? That's where the money is.

Look at this weld. It looks solid.

This is **Iridium-192**. A Gamma Source.

We slide it inside the pipe. We wrap film around the outside.

We are doing **Industrial Radiography**.

We see through steel to find the cracks before the oil spills. No electricity needed. Just a rock that glows with truth.

Paper thickness. Soda levels. Cancer hunting. Steel inspection. That's so cool.

I'll be right back.

Are you smoking?! Around the oil pipeline?! Put it out now!

W-Wha-? How did you find out?

A smoke detector?

**Americium-241**. It uses Alpha particles to ionize the air. Smoke blocks the flow.

There is a nuclear reactor in our bedroom ceiling. For just $10, it saved our lives from your stupidity!

It's invisible.

The nuclear world is layered on top of the normal world, measuring it, fixing it, checking it.

It is the **Backend Infrastructure** of reality.

I don't just want to sell power.

I want to sell **Certainty**. I want to sell the ability to see the invisible.

Then stop looking at the turbine.

Look at the **Isotopes**. That's where more high-margin businesses for nuclear physics lies.
