Today, decades after operations ceased, radiation levels remain alarmingly high, creating an eerie monument to one of the nation’s most consequential scientific endeavors. This is the story of America ...

Radiopharmaceutical experts and researchers to gather June 19-20 in New OrleansNEW ORLEANS, May 12, 2025 (GLOBE NEWSWIRE) -- The first-ever U.S.-based meeting of the World Astatine Community will ...

Radiopharmaceuticals exert anticancer effects by inducing cytotoxic DNA damage through, for example, reactive oxygen species generation, induction of single and double-strand breaks and inhibition of ...

The innovation is a small coin-sized battery powered by a radioactive nickel isotope that decays into stable copper. While the initial cell is relatively weak, it can easily be layered to provide ...

Earth must have experienced something exceptional 10 million years ago. Our study of rock samples from the floor of the Pacific Ocean has found a strange increase in the radioactive isotope ...

This was puzzling: radioactive decay follows strict laws, meaning something must have introduced extra beryllium-10 into the crust at that time. Scepticism is crucial in science.

To give an idea of how radioactive this waste is when it comes out of the reactor, it gives off 10,000 rem/hour of radiation for the next 10 years. Just 500 rem/hour is enough to kill a human being.

Some isotopes are stable, while others are radioactive and decay over time, emitting radiation. Carbon-14 is a radioactive isotope of carbon, meaning that it undergoes beta decay, releasing electrons.

But carbon-14 is unstable and undergoes radioactive decay with a half-life of about 5,730 years, meaning that half of the material will be gone after 5,730 years.
