toriumpäiväys
Toriumpäiväys, also known as thorium dating, is a radiometric dating method used to determine the age of materials containing thorium. This technique relies on the radioactive decay of thorium isotopes, primarily thorium-232, and its subsequent daughter products. Thorium-232 has a half-life of approximately 14 billion years, making it suitable for dating very old geological samples.
The process involves measuring the ratios of parent thorium isotopes to their stable or long-lived daughter
Thorium dating is often employed in conjunction with other radiometric dating techniques, such as uranium-lead dating,
