Radioactive isotope.

You know what a radioactive isotope is?

When he first came to this country, I attended his lectures... on the curative properties of the radioactive isotope.

Carbon 14, 14C, or radiocarbon, is a radioactive isotope of carbon with a nucleus containing 6 protons and 8 neutrons.

And then another isotope of carbon.

As this isotope is generated by radioactive decay, the result may indicate that Mars lost most of its primordial atmosphere, possibly within the first 100 million years after the planet was formed.

These enrichments (δ) represent the ratio of heavy isotope to light isotope in the sample over the ratio of a standard.

This is my morning's run of isotope 217.

Various cycles in those isotope ratios have been detected.

Radioactive yellow.

But that idea of an isotope is an interesting one.

So we're actually measuring each isotope as a different one.

A radionuclide or radioactive nuclide is a nuclide that is radioactive.

Whoa, oh, oh, oh, oh, whoa, oh, oh, oh, I'm radioactive, radioactive

Uranium and other radioactive substances, products made of such substances and radioactive waste

You're just getting a different isotope, a different version, of the element.

It is not radioactive.

Dumping of radioactive waste

Localization, transport and burial of radioactive waste, deactivating materials and maintaining radioactive waste repositories

Determined to keep Africa free of environmental pollution by radioactive wastes and other radioactive matter,

Nuclear transmutation is the conversion of one chemical element or isotope into another.

Now an isotope is the same element with a different number of neutrons.

Greek'aktis' for'beam ' actinium is radioactive

They gave me radioactive iodine.

We picked up radioactive contamination.

I wait carbon 14's half life this is a specific isotope of carbon.

Francium 223 is the most stable isotope, with a half life of 21.8 minutes, and it is highly unlikely that an isotope of francium with a longer half life will ever be discovered or synthesized.

A Radioactive Bank to be Welcomed

Latin'radius' for'beam ', as it is radioactive

Prohibition of dumping of radioactive wastes

The production rate of a particular isotope depends on the energy of the oxygen beam.

Another isotope of carbon is carbon 14, which is much more scarce on the planet.

So when you have the same element with varying number of neutrons, that's an isotope.

Whoa, oh, oh, oh, oh, whoa, oh, oh, oh, I'm radioactive, radioactive All systems go, the sun hasn't died
