What is na 22?

Na 22 is a radioactive isotope of sodium with a half-life of 2.6 years. It decays by beta emission, producing a stable isotope of magnesium, Mg 22. Na 22 is commonly used in medical applications, such as positron emission tomography (PET) scans, which are used to detect cancers and other abnormalities in the body. It is also used in research studies related to metabolism and other biochemical processes in living organisms. Na 22 is produced in nuclear reactors or through the bombardment of stable sodium with neutrons. It is important to handle Na 22 with care as it is a radioactive material and can be hazardous without adequate safety precautions.
