For Radioisotope we have terms and definitions in 12 topics. The topics are Cancer, Energy, Environmental Toxins, Health, Legal, Mesothelioma, Lymphoma, Microbiology, Nuclear, Nuclear Science, Prostate Cancer, Science and Toxic Substances.

A radioactive material frequently used in, in minute amounts, in imaging procedures to safely diagnose or treat disease, or to evaluate response to treatment.

A radioactive isotope.
See more Energy Terms ...

An unstable isotope of an element that eventually will undergo radioactive decay (i.e., disintegration). Radioisotopes with special properties are produced routinely for use in medical treatment and diagnosis, industrial tracers, and for general research.
See more Environmental Toxins Terms ...

A radioactive material injected into the body so that a nuclear scanner can make pictures.
See more Health Terms ...

A type of atom that is unstable and prone to break up (decay). This break-up gives off small fragments of atoms and energy. Exposure to certain radioisotopes can cause cancer. Radioisotopes can also be used to treat cancer. During some tests, radioisotopes are injected into the blood. They travel through the body and collect in areas where the disease is active, showing up as highlighted areas on the pictures.
See more Legal, Mesothelioma Terms ...

An unstable molecule that releases radiation as it decays. Can be used in testing or as treatment.
See more Lymphoma Terms ...

Unstable molecule that emits detectable radiation (gamma rays, X-rays, etc.) for a known period of time (half-life). Can be incorporated into other compounds as a label for later detection by X-ray film exposure or by measurement in a scintillation counting instrument.
