Used fuel contains the highly radioactive products of fission (see high level waste below).

In reactors, the radioactive products are the nuclear waste in spent fuel.

Colgate studied the radioactive products of an explosion which were scooped from the atmosphere by specially designed aircraft.

However this did not stop Bailey from trading in radioactive products.

Not that radon is harmless; under certain conditions, its radioactive products can cause lung cancer.

There is always a cost to division, and in the case of nuclear fission it is the long-lived waste radioactive products.

The risk came from iodine-131, a radioactive product of the explosions that got into milk after cows ate contaminated grass.

A byproduct is spent fuel with plutonium and other highly radioactive products, which can be processed to make bomb ingredients.

"A better estimate of the shielding and radioactive products."

Yet, we are aware that many radioactive products including the most toxic, such as plutonium, are being transported around Europe.
