Podcast Episode 38: Radiometric Dating Explained, Part 1

This is Part 1 of two parts, the next to be in the next episode, conveniently, and will discuss what young-Earth creationists say about the topic.

But in this one, I give you a 50-minute interview with geologist Rachael Acks who explains some of the history of radiometric dating, the very basic physics of it, how it works in practice, and some cases of when and why you can’t use the method.

This month begins a four-part series (though it’ll be labeled as two Parts 1 and 2) on age-dating techniques and then the young-Earth response. The first set is radiometric, second set will be craters. It’s a bit of a different thing, so we’ll see how it works out.

Note that because this interview ran longer than I like to make normal episodes, I’m pushing the not-main segments to Episode 39.


  1. Sounds good! *downloads, starts up computer game*

  2. I was reminded of this episode while watching an episode of a 1950’s science fiction series called “Science Fiction Theater”. The episode called ‘Sun Gold’ is the earliest theatrical version of the ancient astronaut notion I’ve come across as dating from 1956, it even predates von Däniken. In the opening part of the episode it has a couple of scientists ‘carbon date’ a piece of Trinitite found in Peru the age of which later leads to the discovery that aliens influenced the Incan civilization.
