Half-Life _ GCSE Physics
When a radioactive atom goes through alpha or beta decay, the atom itself changes into a different element. For example, carbon-14 decays to nitrogen-14 when it emits beta radiation. It’s impossible to predict when an individual atom...

Radiometric Dating: Carbon-14 and Uranium-238
When you read about the ages of certain ancient artifacts, or even the age of the earth itself, how do we know such numbers? How can we know that a fossil is precisely 250 million years old? The key technique here is radiometric dating....
