Who started carbon dating
a bad rap, what with radiation and fallout and nuclear waste and all. One of the coolest (OK, maybe the coolest) is using radioactive carbon to determine the age of old bones or plants.
To understand this, you must first understand radioactivity and decay.
This is fine, because when carbon-14 decays, it produces nitrogen-14. But you could imagine that if you knew that the sample started with 20 percent blue spheres and you knew their half-life, then you could determine the age by examining one frame from the animation.Carbon-dating Carbon dating, like other radiometric dating methods, requires certain assumptions that cannot be scientifically proved.These include the starting conditions, the constancy of the rate of decay, and that no material has left or entered the sample.When an element undergoes radioactive decay, it creates radiation and turns into some other element.Of course, the best way to understand something is to model it, because the last thing you want to do at home is experiment with something radioactive. Before doing any modeling, you must first understand one key idea: Each atom in a sample of material has an essentially random chance to decay.
