'''Radiometric dating''' is a method of determining the age of an artifact by implausibly assuming that decay rates have been constant (see below for the flaws in that assumption) and measuring the amount of radioactive decay that has occurred.<ref>[http://pubs.usgs.gov/gip/geotime/radiometric.html Radiometric Time Scale] USGS</ref> Radiometric dating is mostly used to determine the age of rocks, though a particular form of radiometric dating&mdash;called [[Radiocarbon dating]]&mdash;can date wood, cloth, skeletons, and other organic material.

Because radiometric dating fails to satisfy standards of testability and [[falsifiability]], claims based on radiometric dating may fail to qualify under the ''[[Daubert]]'' standard for court-admissible scientific evidence.

Because radiometric dating fails to satisfy standards of testability and [[falsifiability]], claims based on radiometric dating may fail to qualify under the ''[[Daubert]]'' standard for court-admissible scientific evidence.  It is more accurate for shorter time periods (e.g., hundreds of years) during which controlling variables are less likely to change.
