Atoms containing this unstable combination regain stability by shedding radioactive energy, hence the term radioisotope.The process of shedding the excess radioactive energy is called radioactive decay.Radioisotopes are commonly used in industrial radiography, which uses a gamma source to conduct stress testing or check the integrity of welds.A common example is to test aeroplane jet engine turbines for structural integrity.
Its radioactivity attacks nearby cancer cells with minimal effect on healthy tissue.
After entering the body, the radio-labelled pharmaceutical will accumulate in a specific organ or tumour tissue.
The radioisotope attached to the targeting pharmaceutical will undergo decay and produce specific amounts of radiation that can be used to diagnose or treat human diseases and injuries.
The radioactive decay process of each type of radioisotope is unique and is measured with a time period called a half-life.
Radioisotopes are an essential part of radiopharmaceuticals.
