Radiometric Dating

noun a type of mass spectrometry that is used to analyze samples at the atomic level

• Accelerator mass spectrometry is a highly sensitive technique used for radiocarbon dating.
• So they used this thing called accelerator mass spectrometry to figure out how old the artifact was.
• They zapped the sample with accelerator mass spectrometry to get the date.
• Using accelerator mass spectrometry is like peering into the past with a high-powered microscope.

noun A series of radioactive elements that starts with actinium and ends with lead-206, including actinium, thorium, protactinium, uranium, and various isotopes of these elements.

• The actinium series is a radioactive decay chain that starts with the element actinium-227.
• Did you know about the actinium series and how it decays over time?
• Yo, the actinium series is like a chain reaction of radioactive elements.
• The actinium series can be compared to a domino effect, with each element decaying into the next.
