Virtual radioactive dating lab
After all, textbooks, media, and museums glibly present ages of millions of years as fact.Yet few people know how radiometric dating works or bother to ask what assumptions drive the conclusions. This figure wasn’t established by radiometric dating of the earth itself. Radiohalos shouldn’t exist, according to conventional wisdom!Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample.

Radioactive dating requires the use of a decay curve.
Introduction: Scientists use radioactive dating to determine the time in years ago that an event happened.
