The smaller the ratio, the longer the organism has been dead. So, if radioactive iodine-131 (which has a half-life of 8 days) is injected into the body to treat thyroid cancer, itll be gone in 10 half-lives, or 80 days. Pre-Flood material would be dated at perhaps christian dating ten times the true age.
Learn about different types of radiometric dating, such as carbon dating.
Understand how decay and half life work to enable radiometric dating.
Cosmic rays are positively charged atoms moving at enormous speeds.
When they strike ordinary atoms in the upper atmosphere, the cosmic rays smash them apart. Some of these neutrons then collide with nitrogen atoms.
the atmosphere (12C behaves like 14C and also combines with oxygen) to form carbon dioxide (CO2). Because of this false assumption, any age estimates using 14C prior to the Flood will give much older dates than the true age.This collision is less destructive than the initial collision that produced them.Usually a proton is knocked out of the nitrogen atom's nucleus and is replaced with the neutron.Only one out of every trillion carbon atoms is C14. The C14 created in the upper atmosphere reacts with oxygen to become carbon dioxide.The carbon dioxide is absorbed by plants, and the plants are eaten by animals, thus contaminating every living thing on earth with radioactive carbon. As time passes, the C14 in its tissues is converted back into nitrogen.
