Radiochemistry It is the division in chemistry that deals with chemical reactive phenomena using radioactive practices . In it, radioactive isotopes are used to fix the mechanism and ramification of chemical reactions, analyzing the radioactive decay of the reactants, products and reactive intermediates.

Types of Radiations
- Alpha Radiation: Consists of the emission of alpha particles by an atomic nucleus . They are highly ionizing although not very penetrating, alpha radiation is blocked by just a few centimeters of air or thin sheets of some solids.
- Beta radiation: Consists of the emission of electrons (beta negative) or positrons (beta positive)) that come from the decay of neutrons or protons of a nucleus in an excited state. This radiation is deflected by magnetic fields. Its ionizing power is not as high as that of the previous one, however it is more penetrating, it can be blocked by thin sheets of many solids.
- Gamma Radiation: Consists of the emission of electromagnetic waves of short wavelength. It is the most penetrating radiation, very thick layers of lead or barium , or concrete are needed to stop it or reduce its intensity.
Applications in science
- Radiotherapy: Through radiation with ionized atoms , the reduction of cancer tumors is studied, with the ultimate goal of stopping their growth, expansion in the human system, or completely destroying them.
- Radiodiagnosis: By injecting controlled doses of ionizing or non-ionizing radiation (depending on the case), it is studied how the radiation spreads or how the system reacts. The method of observations is through images and blood tests. With this method, it was possible to detect diseases that still have no symptoms.
How metabolisms react to the application of radiation with special isotopes (Carbon-14 combinations) are studied.
Archeology and Geology :
You can determine the age, the region and even the reasons for their death (in the latter case, in the case of living beings)
Environmental Chemistry :
The study of radioisotopes present in the environment (radioactive contamination), both natural and artificially produced, is of great importance , since high levels of these affect both human health and the environment
