How is radioactive dating performed
Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. As we age, our hair turns gray, our skin wrinkles and our gait slows.
"Radiometric dating - the process of determining the age of rocks from the decay of their radioactive elements" Wiens, RC 2002, Radiometric Dating A Christian Perspective, 'Science in Christian Perspective', The American Science Affiliation, viewed 8 September 2009, Carbon dating is one type of radiometric dating, there are others.
The proportion of potassium to argon suggests how old the object in question is.
An equation used is t = (1/c)Ln(1 (D/P)) Where c is the decay constant D is number of daughter atoms (number decayed) P is the number of parent atoms (number undecayed) t is the age of the object.
But results can be gotten that are surprisingly accurate.
As a "for instance" we might look at uranium-lead dating.
