Radiometric dating calculates an age in years for geologic materials by measuring the presence of a short-life radioactive element, e.g., carbon-14, or a long-life radioactive element plus its decay product, e.g., potassium-14/argon-40.

What is meant by radiometry?

Radiometry is the science that studies the measurement of electromagnetic radiation. The instruments designed for measuring the energy flux of electromagnetic radiation are generically referred to as radiometers.

What is radiometric test?

Radiometry involves measuring and predicting levels of optical radiation. The two most common are the description and measurement of optical radiation, and, starting with the knowledge of some aspects of optical radiation at one location, predicting the measurement that would be made at another.
