Radiometric dating , radioactive dating or radioisotope dating is a technique which is used to date materials such as rocks or carbon , in which trace radioactive impurities were selectively incorporated when they were formed. The method compares the abundance of a naturally occurring radioactive isotope within the material to the abundance of its decay products, which form at a known constant rate of decay. Together with stratigraphic principles , radiometric dating methods are used in geochronology to establish the geologic time scale. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.

Use this decay calculator to easily calculate the time elapsed since the beginning of the decay, or calculate the original quantity, half-life or remaining quantity of a substance subject to radioactive decay, based on any of the three parameters. Convert half-life to mean lifetime or decay constant, and vice versa by entering any of the three values in its respective field. Our versatile radioactive decay calculator supports many different time units and automatically converts them if the time unit you measure the time elapsed is different than the time unit you enter the half-time, decay constant or mean lifetime in. Supported units are nanoseconds, milliseconds, seconds, minutes, hours, days, weeks, months, and years. Months are approximated to The half-life calculator results are accurate to the th decimal and are usable in physics, chemistry, etc. Radioactive decay a.

Radiometric dating is a technique used to date materials based on a knowledge of the decay rates of naturally occurring isotopes , and the current abundances. It is our principal source of information about the age of the Earth and a significant source of information about rates of evolutionary change. All ordinary matter is made up of combinations of chemical elements , each with its own atomic number , indicating the number of protons in the atomic nucleus. Additionally, elements may exist in different isotopes , with each isotope of an element differing only in the number of neutrons in the nucleus.
Following the somewhat serendipitous discovery of radioactivity by Becquerel, many prominent scientists began to investigate this new, intriguing phenomenon. During the beginning of the twentieth century, many radioactive substances were discovered, the properties of radiation were investigated and quantified, and a solid understanding of radiation and nuclear decay was developed. The spontaneous change of an unstable nuclide into another is radioactive decay.
