This method, known as targeted radionuclide therapy, or TRT, involves the use of molecules labeled with radioactive atoms that are injected into patients and localized in cancer cells.

The man with radioactive atoms flowing through his veins seems calm.

We've already done that with the opposite reaction, fission — the breaking of large atoms into smaller particles — which leaves us with the troublesome byproduct of radioactive waste.

The researchers bombarded radioactive americium - 243 with calclium - 48, shooting one trillion calcium atoms per second at the americium target, hoping that occasionally the atoms would stick together to form something new.

In 1899 Ernest Rutherford noticed that half of the atoms in a sample of radioactive radon gas disappeared with each passing minute.

Curium was only discovered in 1944, by Glenn Seaborg and his collaborators at the University of California, Berkeley, who, by bombarding atoms of plutonium with alpha particles (atoms of helium) synthesized a new, very radioactive element.

For instance, radiocarbon dating determines the age of biological remains based on the ratio between the carbon isotopes (atoms of the same element with different numbers of neutrons) carbon - 12 and carbon - 14 it holds - this proportion changes as radioactive carbon - 14 breaks down while stable carbon - 12 does not.

G. Brent Dalrymple's classic debunking of the young - earth «scientific» creationism's dating methods with a short explanation of how geologists know the age Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample.

It is not clear that the authors consider how long radioactive atoms remain in our body, since we excrete them along with other atoms; the numbers below may overstate the case as the authors assume a residence time as long as 50 years.
