So, if you know the radioactive isotope found in a substance and the isotope's half-life, you can calculate the age of the substance. Well, a simple explanation is that it is the time required for a quantity to fall to half of its starting value.So, you might say that the 'full-life' of a radioactive isotope ends when it has given off all of its radiation and reaches a point of being non-radioactive.
QUESTION: Can we date sedimentary rocks using radiometric dating techniques?
ANSWER: Sedimentary rocks cannot be dated directly using radiometric dating, which is based on the idea that when rocks are in liquid form, their radiometric clock resets.
Find additional lessons, activities, videos, and articles that focus on relative and absolute dating.
Radioactive elements were incorporated into the Earth when the Solar System formed.
Radioactive decay is a natural process and comes from the atomic nucleus becoming unstable and releasing bits and pieces.
