Today, carbon-14 dating is much more than just a method used by archaeologists. Thanks to advances in analytical techniques, it is used in many fields, including the study of archaeological remains, the authentication of works of art, the testing of bio-based materials, the protection of biodiversity, and scientific research.
The basic principle remains the same: measuring the amount of carbon-14 present in an organic material. However, its applications vary depending on the objectives and the materials being analyzed.
In this article, learn about the main areas of application for carbon-14 that the CIRAM laboratory is working on, as well as the specific challenges associated with each one.
In summary:
- Carbon-14 has numerous applications in archaeology, the art market, industry, and the environment.
- The same scientific method can be used to address very different problems depending on the field of application.
The Main Applications of Carbon-14
In archaeology: establishing the chronology of the remains
Carbon-14 dating is one of the primary dating methods used in archaeology. It allows researchers to date a wide range of organic materials—such as charcoal, bones, teeth, seeds, textiles, and peat—in order to place archaeological finds in their chronological context.
When combined with other methods such as thermoluminescence (TL), OSL, or isotopic analysis, this method helps reconstruct the history of archaeological sites and ancient populations.

To authenticate works of art
In the field of cultural heritage, carbon-14 dating is used to determine the age of a work’s organic materials: wood, canvas, paper, ivory, or textiles. The results help verify whether the material is consistent with the stated period of creation.
For materials produced after the 1950s, the post-bomb effect even provides a particularly high degree of accuracy and makes it easier to detect recent forgeries.

To analyze bio-based materials
Carbon-14 is not used solely for dating. In industry, it is also used to measure the proportion of carbon of biological origin and to distinguish bio-based materials from fossil-based materials. This analysis meets the requirements of numerous standards and certifications applicable to plastics, paints, cosmetics, and fuels.
Here are a few examples:
