PART 1: Back to Basics PART 2: Problems with the Assumptions PART 3: Making Sense of the Patterns This three-part series will help you properly understand radiometric dating, the assumptions that lead to inaccurate dates, and the clues about what really happened in the past.

Most people think that radioactive dating has proven the earth is billions of years old.

Radiodating isotopes

In some cases, the isotopes eject particles, primarily neutrons and protons.

(These are the moving particles measured by Geiger counters and the like.) The end result is a stable atom, but of a different chemical element (not carbon) because the atom now has a different number of protons and electrons.

Each atom is thought to be made up of three basic parts.

The nucleus contains protons (tiny particles each with a single positive electric charge) and neutrons (particles without any electric charge).

Actually, it isn’t really a decay process in the normal sense of the word, like the decay of fruit.

The daughter atoms are not lesser in quality than the parent atoms from which they were produced.

These parent radioisotopes change into daughter lead-206, lead-207, argon-40, strontium-87, and neodymium-143 isotopes, respectively.

Thus geologists refer to uranium-lead (two versions), potassium-argon, rubidium-strontium, or samarium-neodymium dates for rocks.

So let’s take a closer look and see how reliable this dating method really is.
