Radiogenic isotope dating

Most people think that radioactive dating has proven the earth is billions of years old.Yet this view is based on a misunderstanding of how radiometric dating works.An accessible introduction for scientists from other disciplines and an important reference for students and researchers working in isotope geology.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.

A method for determining the age of an object based on the concentration of a particular radioactive isotope contained within it.

For each technique, current ideas are presented in their historical context to allow the reader to understand the development of the theory.

The latest ideas and methods, classic papers and case studies all come under scrutiny within this book.

Part 1 (in the previous issue) explained how scientists observe unstable atoms changing into stable atoms in the present.

Part 2 explains how scientists run into problems when they make assumptions about what happened .

After the passage of two half-lives only 0.25 gram will remain, and after 3 half lives only 0.125 will remain etc.
