# Types of radioactive dating justiedating com

As any first-year student of algebra soon learns, a single equation with two unknown variables cannot be solved.In fact, the above formula is far too simple, because it assumes that the amount of daughter isotope was zero at start.The proportion of argon to radioactive potassium in the sample today is observable, and the decay constant of potassium is readily calculable by measuring the amount of argon produced from the decay of K after a specified time.

These out of place fossils or rocks are not considered a reason to question the theory.For example, K-Ar dating assumes that there was no argon in the original rock.But if there was argon in the rock when it originally formed, then the age calculated will be millions of years too high. The greater the amount of daughter isotope, the greater the apparent age.Other methods such as Potassium-argon dating and Isochron dating are based on faulty assumptions and so unreliable as to be useless.Many atoms (or elements) exist as numerous varieties called isotopes, some of which are radioactive, meaning they decay over time by losing particles.
