The statement is meaningless without an estimate of the risk per event.

Let's consider the source of the nearly 8000 radioactive events that take place in our bodies every second.

RADIOACTIVE ELEMENTS IN THE HUMAN BODY Rb) are termed primordial radioisotopes, for they were present when the earth was formed.

The fact that they are still present in our environment is due to the fact that their half lives are comparable to the age of the earth, and thus they have not yet decayed into stable elements.

This is the second lesson in a three-lesson series about isotopes, radioactive decay, and the nucleus.

These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing.

As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils.

For example, in 1991, two hikers discovered a mummified man, preserved for centuries in the ice on an alpine mountain.

Later called Ötzi the Iceman, small samples from his body were carbon dated by scientists.
