The answer to your first question seems to be yes, radioactive dating does lead to radar love, love at first sight!
On the second question, here is some info of how ten-year-old rocks from Mt. St. Helen's tested millions of years old:
It is clear that radioisotope dating is not the ‘gold standard’ of dating methods, or ‘proof’ for millions of years of Earth history. When the method is tested on rocks of known age, it fails miserably. The lava dome at Mount St Helens is not a million years old! At the time of the test, it was only about 10 years old. In this case we were there—we know! How then can we accept radiometric-dating results on rocks of unknown age? This challenges those who promote the faith of radioisotope dating, especially when it contradicts the clear eyewitness chronology of the Word of God.
Sample Age / millions of years
1 Whole rock 0.35 ± 0.05
2 Feldspar, etc. 0.34 ± 0.06
3 Amphibole, etc. 0.9 ± 0.2
4 Pyroxene, etc. 1.7 ± 0.3
5 Pyroxene 2.8 ± 0.6
