UniformityRadioactive dating is a way of determining the age of a specimen or fossil bydetermining how much of the radioactive material is left. By figuring out what is left behindwe can work backwards to figure out the half-lives of a specimen to determine\the age of the specimen (What is Dating , 216). Radioactive substances have what is called ahalf-life. The half life of the radioactive material is determined by figuring out the amount ofthe time which must elapse to decrease the material by a half. By figuring the half-lives fromthe fraction of material left the age of the fossil is found. The decay occurs at predeterminedintervals which have not changed throughout the history of earth. The rates of decay are notsubject to change based on climate, temperature, or any other conditions. This is important todetermine an accurate calculation of the age of the sample. The most usedtechniques forradioactive dating are radiocarbon dating, potassium-argon dating, and uranium-lead dating
