The testing of thermonuclear weapons produced an increase in atmospheric C they contain is infinitesimal.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.
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 .
One rare form has atoms that are 14 times as heavy as hydrogen atoms: carbon-14, or C ratio gets smaller.
So, we have a “clock” which starts ticking the moment something dies.
Obviously, this works only for things which were once living.
