Examples of radioisotope in the following topics:
-
- A radioactive tracer is a chemical compound in which one or more atoms have been replaced by a radioisotope.
- A radioactive tracer is a chemical compound in which one or more atoms have been replaced by a radioisotope.
- By virtue of its consequent radioactive decay, this compound can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products.
- All the commonly used radioisotopes (Tritium (3H), 11C, 13N, 15O, 18F, 32P, 35S, 99mTc, and 123I; see ) have short half-lives.
-
- Carbon-14 dating is a radiometric dating method that uses the radioisotope carbon-14 (14C) to estimate the age of object.
- It uses the naturally occurring radioisotope carbon-14 (14C) to estimate the age of carbon-bearing materials up to about 58,000 to 62,000 years old.
- There are also trace amounts of the unstable radioisotope carbon-14 (14C) on Earth.
-
- Because of this exponential nature, one of the properties of an isotope is its half-life, the time by which half of an initial number of identical parent radioisotopes have decayed to their daughters.
- Half-lives have been determined in laboratories for thousands of radioisotopes (radionuclides).
- The intermediate stages often emit more radioactivity than the original radioisotope.
-
- Even the lightest element, hydrogen, has a well-known radioisotope: tritium.
- For every chemical element, many radioisotopes that do not occur in nature (due to short half-lives or the lack of a natural production source) have been produced artificially.

- Brachytherapy is another form of radiation therapy, in which a therapeutic radioisotope is injected into the body to chemically localize to the tissue that requires destruction .

-
- With most designs the radioisotope can be lowered into a water-filled source storage pool to allow maintenance personnel to enter the radiation shield.
-
- PET acquisition process occurs as the radioisotope undergoes positron emission decay (also known as positive beta decay), it emits a positron, an antiparticle of the electron with opposite charge.
-
- Natural sources of gamma rays on Earth include gamma decay from naturally occurring radioisotopes such as potassium-40, and also as a secondary radiation from various atmospheric interactions with cosmic ray particles.
