Which of the following is true about radiometric dating?
Since the half-life of carbon-14 is 5,730 years, radiocarbon dating methods are limited to about 60,000 years.
Radiometric dating is a relative dating method that infers the age of a fossil by noting the relative position of the rock layer in which it is found.
Radiometric dating is based on measuring current solar output and comparing it to the amount of carbon in plant fossils that was produced by photosynthesis in the past.
Radiometric dating is dangerous, since the researcher is exposed to high doses of radiation.
