What isotopes can be used for radioactive dating
It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.
Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers.
Agencies and manufacturers are also able to determine the method of feeding for livestock -- organic or conventional -- by analyzing carbon, nitrogen and sulfur isotopes.
His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.
Christopher de la Torre has been writing about science and communication since 1998.
His work appears on websites including Singularity Hub and in "Vogue." He holds a Bachelor of Science in biology and a Bachelor of Arts in English from Eastern Connecticut State University and is pursuing a master's degree in English from George Mason University.
There are many potential uses for isotopes in experimentation, but several applications are more prevalent.
Each chemical element has a unique number of protons, a fact that gave rise to the periodic table.
