Due to the way radiometric dating works, you don't need to actually verify in the way that you are using the word. However, there are at least two ways to verify the date: 1) Verify the half-life value. Radiometric dating works on the same principle: look at the ratio of pre-substance to fissioned substance. If you have a good half-life value, you can determine the age of the specimen using those values. 2) Use two different methods for getting the same age. If you use multiple, independent methods of determining the age of something, and they all come out the same, you have greatly lessened the probability that you're wrong or missed something. Of course there are ways that these can be strengthened even more using practices like double blinding the measurements.
