that we've hinted at with this record.or isotopes in this case, aren't that dense in our record.
or isotopes in this case, aren't that dense in our record.
of isotopes and DNA.
and another isotope of hydrogen called tritium that has two neutrons and a proton.
This is a stable isotope.
We could get an isotope of cesium and watch it vibrate 9 billion-plus times.
And one isotope, the lighter isotope, if I'm not mistaken, is the one that's used in actually producing nuclear fuel in bombs.
The other isotope, the heavier isotope, is actually not used.
But we did develop isotope-powered batteries that are atomic in the sense that they're
And it's isotope-powered and it's been isotope-powered since it launched 33 years ago. And I just mention the isotope batteries because, actually right now in the US, we have a crisis of isotope
And using the radiocarbon isotopes, or bomb radiocarbon, we can actually go back and date each one of those sections, and say, oh, this animal was born in 1953.
of Half Moon Bay-- the isotope analysis of that water table shows that the fog has a very significant impact on that watershed.
It's a sort of the default isotope.
He should have been finalizing his isotope indicators, proofreading.
And they were trying to isolate carbon isotopes, radioactive carbon isotopes.
uranium that exists there's two isotopes u-235 u-238 many of the advanced reactor designs can go upwards of you know close to 50%
And you can look at the oxygen isotopes to reconstruct temperature.
It's really hard to change these isotopes.
And by measuring the ratios of those isotopes and making certain assumptions about intake and outflow of ions, you can date bone going back
powered by decay and half-life of isotopes.
We're working on fusion where we would merge a particular isotope of hydrogen, called deuterium, that has one proton and one neutron,
We went and used this technique called compound specific stable isotope analysis in amino acids.
taking the most common elements in the universe: hydrogen and lightweight isotopes of hydrogen and helium, and fusing those together to make heavier elements.
So he'd been thinking about how radioactive isotopes are made.
Now, there are two isotopes of uranium that are basically found in nature.
And we know that because we can study the isotopes, the bone isotopes.
they used it in developing the atomic bomb they isolated isotopes, and all that fun stuff.
She started with cobalt 60, an isotope of cobalt where the nucleus has an intrinsic angular momentum, or spin.
- So in fusion, you take these lightweight isotopes like hydrogen and deuterium, and as you combine them and get them closer and closer together, some really interesting fundamental physics happens.
process, which is take these lightweight isotopes, heat them up, so that they can move at high velocity, over 100 million degrees, bring enough of them together.
So one of the side products of this was a lot of the isotopes of plutonium we could use for this.
that is old lead, the radioactive isotopes have decayed and they use that to shield the experiment from the new lead and so on and so forth.
What the researchers are able to do other than study the fog drift is they're able to do an isotope analysis of the water table from well water.
I did a do it yourself version of this experiment in my basement using a radioactive isotope, sodium-22.
know, inches thick of lead and lead itself has a radioactive isotope, lead 210, which decays, so in order to protect that, uh, sort of decaying lead from the
process in fusion as you're bringing those lightweight atomic nuclei, those isotopes together.
But if the moon was a separate body that formed elsewhere in the solar system, its isotopes would be way different from Earth’s.
And we drill out powder from there, and we analyze the isotopes.
And it turns out you can fingerprint the source of water by the ratio of the heavy to light water isotopes that you see.
So the oxygen, led, and strontium isotopes that you eat and go into your bones and your teeth, we can use those to source where people lived in the past,
Well, what about using nuclear fusion to make radioactive medical isotopes?
And so here, we've got carbon and nitrogen isotopes, and we're looking at individuals from these different houses.
Because what you really want to do is all sorts of experiments on chemical analysis to try and understand the isotopes in the ice.
- Is everywhere, and we particularly use a type of hydrogen called deuterium, which is a heavier isotope of hydrogen.
What happens in this case is a neutron-- that's what the n is, a small subatomic particle with no electric charge-- comes in and hits an isotope of uranium,
This a neutron and a proton, an electron, so it's a deuterium isotope of hydrogen.
And what happens when you bombard thorium with neutrons, it goes through a nuclear decay chain and eventually reaches actually an isotope of uranium, which is U-233.
So uranium, plutonium for the fission, and then hydrogen isotopes for the fusion?
In fusion, you're taking these lightweight isotopes, you're bringing them together, you're releasing energy,
Then, it orbited there for years before Earth began to cool and shrink, dividing the synestia into two separate bodies with nearly identical isotopes.
