What isotopes can be used for radioactive dating
Because the life of a radioisotope isn't affected by any influence outside of the nucleus, its predictable rate of decay acts like a clock.
Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers.
