Radiometric dating radiometric dating and proof radiometric dating different radioactive isotopes can be used it does not seem that you understand its meaning. Radiocarbon dating is mentioned all the time in science, but what does it mean most people do not know well, to first understand radiocarbon dating, one has to comprehend the meaning of the word “isotope”. Reader @procrustes tweeted at us to ask: “why do scientists measure things like radioactive elements in half-life why not just measure the whole life” if you’re not familiar with the term “half-life,” maybe you’ve heard one of your nerd friends use it. Radioactive dating is a technique used to find how old an object is one such example is potassium-argon dating, where potassium decays into argon the proportion of potassium to argon suggests how old the object in question is.
