Isotooppiaineistomenetelmä

Isotooppiaineistomenetelmä, often translated as isotopic tracer method or isotope analysis, is a scientific technique used to study the origin, movement, and transformation of substances. It relies on the principle that different isotopes of the same element, while chemically identical, have distinct physical properties that can be detected and measured. These isotopes are incorporated into a substance and then tracked as the substance undergoes natural or experimental processes.

The core of the method involves using naturally occurring or artificially introduced isotopes as tracers. For example, stable isotopes like deuterium (a heavy isotope of hydrogen) or carbon-13 can be used, or radioactive isotopes such as carbon-14. By analyzing the ratio of different isotopes in a sample, scientists can deduce information about its history. For instance, in environmental studies, isotopic analysis of water can reveal its origin and flow paths. In archaeology and paleontology, the isotopic composition of fossils or artifacts can provide clues about diet, migration, or the environment in which they formed.

Isotope analysis is a versatile tool employed across various scientific disciplines including geochemistry, hydrology, biology, environmental science, and forensics. Its ability to provide quantitative data without disrupting the system being studied makes it invaluable for understanding complex natural and human-induced processes. The accuracy of the method depends on precise measurements of isotope ratios, often achieved using mass spectrometry.
