For these reasons, if a rock strata contains zircon, running a uranium-lead test on a zircon sample will produce a radiometric dating result that is less dependent on the initial quantity problem.

Another assumption is that the rate of decay is constant over long periods of time.

Because this new element (decay product) remains on or within the object, scientists can easily determine how old the object is. A mass spectrometer is a fundamental device in any radiometric dating experiment.

Mass spectrometers can be used to measure isotopic samples as small as one 1 nanogram.

This works because elements have a life cycle known as a “half-life.” A half-life refers to the amount of time it takes for an isotope to lose half of its atoms as a result of decaying.

When an isotope decays, it often becomes a different kind of element altogether.

Advantages and Disadvantages Radiometric dating has several important advantages and disadvantages, but is the only practical method scientists currently have for dating objects.

Advantages include the ability to date an object without destroying it, having many different techniques to choose from, and the ability to procure a relatively accurate age of objects that are hundreds of thousands, millions, or even billions of years old.

However, samples must be taken from several different areas of the object being studied to ensure maximum accuracy.
