Radioactive elements in dating events and artifacts

That is why you need at least two, sometimes three judges to measure the time of the race to the standard needed to enter the record books.

This illustrates the whole problem with the radioactive dating of geological events.

Those who promote the reliability of the method spend a lot of time impressing you with the details of radioactive decay, half-lives, mass-spectroscopes, etc.

A swimming race illustrates the simple principles involved in measuring time.

At 3.5 dpm, the age would be about 11,640 years and so on.

You could talk about the tiny quartz crystal and the piezoelectric effect used to provide a stable time base for the electronic movement.

You could describe the atomic workings of the quartz oscillator and how it resonates at a specific and highly stable frequency, and how this is used to accurately pace a timekeeping mechanism.

Accelerated mass spectrometry (AMS) is the other technique used.
