Radioactive decay could work, but how would people feel about that?

That was clearly shown by the radioactive decay of certain elements.

There are many different types of radioactive decay (see table below).

Most helium on Earth is a result of radioactive decay.

Their radioactive decay produces about half of the earth's internal heat.

This will have an impact on the long-term radioactive decay of the spent fuel.

A specific level of radioactive decay across a uniform spectrum.

Its radioactive decay produces a significant amount of the Earth's internal heat.

If your goal is simply to observe radioactive decay, then you are in luck.

U-232 hazards, a result of its highly radioactive decay products like thallium-208, are significant even at 5 parts per million.

It has a radioactive decay half-life of about eight days.

They also said there were no signs that radioactive decay could have been behind the discrepancy.

All methods based on the radioactive decay belong to this category.

However, due to radioactive decay the nuclear fuel will continue to generate a significant amount of heat.

The number of atoms were counted by observing the radioactive decay.

During the process of radioactive decay, a beta particle will be released.

Other than radioactive decay, there are very few nuclear reactions that occur outside of these special places on earth.

The age of each flow can be estimated from the extent to which certain radioactive decay processes have run their course.

For an approach with a more direct physical basis, some models use the fundamental concept of radioactive decay.

This luminosity is generated by the radioactive decay of nickel-56 through cobalt-56 to iron-56.

Although radiation levels were significantly higher soon after the accident, they have fallen because of radioactive decay.

Their radioactive decay is accompanied by the emission of single protons.

Thermal generators, which use the heat of radioactive decay to make electricity, are still working, too.

There is one type of radioactive decay that is a little bit sensitive to the environment.

This is a well founded major assumption, common to all dating methods based on radioactive decay.
