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 control variables are less likely to change.There are a number of implausible assumptions involved in radiometric dating with respect to long time periods.One key assumption is that the initial quantity of the parent element can be determined.

Likewise, heating the rock such as granite forms gneiss or basalt forms schist.This can also disrupt the ratios of lead and uranium in the sample.In order to calibrate radiometric dating methods, the methods need to be checked for accuracy against items with independently-known dates.The energy locked in the nucleus is enormous, but cannot be released easily.

The phenomenon we know as heat is simply the jiggling around of atoms and their components, so in principle a high enough temperature could cause the components of the core to break out. Radiometric dating is a method of determining the age of an artifact by assuming that on average decay rates have been constant (see below for the flaws in that assumption) and measuring the amount of radioactive decay that has occurred.
