Resumen:
The isotopes of an element have the same number of protons in their atoms (atomic number) but different masses (different neutron number). There are 82 stable elements and about 275 stable isotopes of these elements. Stable radioisotopes are used in the treatment and diagnosis of disease, particularly considering metabolic pathways.
The science and clinical practice of nuclear medicine involve the administration of trace amounts of compounds labeled with radioactivity (radionuclides) that are used to provide diagnostic information and disease therapy in a wide range of pathologies.
Nuclear medicine (diagnostic & treatment) uses alpha, beta and gamma radionuclides. This work concentrates on beta emission, because it is one of the most commonly employed, particularly for diagnostic. There are three different mechanisms (channels) for the beta decay and they can be expressed as follows:
