Radiation, which is a byproduct of radioactive decay, causes electrons to dislodge from their normal position in atoms and become trapped in imperfections in the crystal structure of the material. However, age is not a substance that can be measured by scientific equipment. After three half-lives of this system, totaling 3. The force causing materials, particularly those made of iron and other certain metals, to attract or repel each other; a property of materials that responds to the presence of a magnetic field normal polarity: Comparison of commonly used dating methods. At a certain temperature, the crystal structure has formed sufficiently to prevent diffusion of isotopes. Many naturalists were influenced by Lyell to become "uniformitarians" who believed that changes were constant and uniform.
