Radio active elements

Completely wrong. OK. Utterly backwards.

It's only been with us for less than a century, and in that time, that fourth dimension, when radioactive dating came about, less than a century ago, and we could actually tell how old some of these things were, is probably the most profound transformation, because it changes the way we look at ourselves and the world dramatically.

Selects the color of radioactive elements

Isotope?

Rays consisting of electrons that are emitted from Atoms of radioactive elements.

So we started measuring carbon dioxide in 1958.

And when they eat the seeds, their foie gras turns yellow.

You tried to kill me.

Timereleased radioactive capsules.

I have been trying to determine

So you go which one of these is more dangerous?

This guy, 2.3 million years, no problem. It's not going to hurt you.

You look like a radioactive tampon.

One is, for instance, technetium is a radioactive element with a decay time of 4.2 million years.

Caused by the explosions and meltdowns in the Fukushima Dai ichi Nuclear Power Plants,

Positron Emission Tomography uses a radioactive tracer to visualize metabolic activity within the human body.

If they did, we would be shutting down all of our coal and gas plants based on radioactivity alone.

When the isotope solution turns red, then fire.

Strontium 90 One of the radioisotopes of strontium part of radioactive fallout, harmful to human health.

When you fission something, it breaks into these two pieces, but they're radioactive.

We manufacture them in house, ourselves. That keeps the costs down.

We can make molybdenum 99 just in normal course of operation and we can remove it very easily.

Radioactive isotopes don't give off

Rays consisting of alpha particles, consisting of two protons and two neutrons that are emitted from the Atoms of certain radioactive elements.

That's where I began to get these emanations.

JOE Each unit has a GPS and a Giger counter inside.

Inert nitrogen, high concentration of carbon dioxide crystals, methane...

I realize that they are microfiltration membranes.

Carbon 9 .

Radial

Radiation?

The second way is like this.

We started to realize how important it was when it turned out that the government wasn't releasing data. The day before we took our drive, Safecast volunteers offered up a seminar on radiation detection in Tokyo.

The differed risk!

Will you risk hundreds of millions of people being blasted to radioactive dust?

Just the right amount of radiation at specific times

What are the density parameters associated with different components we see in the universe?

I mean, they make these out of 440 carbon. It's a nonmagnetic steel.

What it is, is a picture of the spectrum of hydrogen.

He had planned on leaving Japan permanently, but his conscience got the better of him and instead of escaping he moved to Fukushima city and helped found the Citizens' Radioactivity Measurement Station.

And that's because we're measuring the weight so precisely that carbon comes in different isotopes, so if it has an extra neutron on it, we actually measure it as a different chemical.

So the number of neutrons can change, but this is carbon 12 right over here.

Now, there was no carbon and oxygen in the universe at the Big Bang.

So how does this work?
