Radiochemistry is a branch of chemistry that studies chemical reactions using techniques based on radioactivity.
Using radioactive isotopes can determine the mechanism of chemical reactions, studying the decay of radioactive reagents, or reaction intermediates.
Some applications
In Medicine
In Biochemistry
By isotopic labeling (carbon-14) were determined metabolites many reactions of metabolic pathways.
In Archaeology and Geology
Due to the existence of natural radioactive isotopes in archaeological objects by radioactivity measurements, these can be dated (carbon-14 method).
In Geology, we can find out the age of the rocks through the study of some radioisotopes (potassium-40 0 uranium-235, for example).
Environmental Chemistry
It is of great importance to study the radioisotopes present in the environment (radiation pollution), both natural and artificially produced, and that elevated levels of these affecting both human health and the environment.
