And this isn’t really an assumption as the decay rates have been tested in the laboratory for a hundred years or so, we have an example of a natural nuclear reactor where we can measure the various products and determine the decay rates (and the fine structure constant), and we can observe the past by looking deep into the past of the universe. The sigh isn’t for the effort of writing, it’s for the effort of finding all the references.

The belief that radiodating methods give absolute measurements of time is widespread as a result of scientific popularization in journals, conferences, and the media.

In fact, due to the difficulties in applying the experimental method to events in the past, all chronometers based on natural or artificial nuclear disintegration need a calibration.
