Carbon dating method reliable
Even though more than one method of verification is used in most cases, the lack of an accurate method to date non-organic materials lends a certain degree of uncertainty to the accepted history of our planet.
This method is based on the fact that when a material is heated or exposed to sunlight, electrons are released and some of them are trapped inside the item.
Once you heat this item again using high temperatures, the trapped electrons become excited and recombine with the item’s material.
This process frees energy in the form of light, which can be measured.
Radiocarbon decays slowly in a living organism, and the amount lost is continually replenished as long as the organism takes in air or food.
Once the organism dies, however, it ceases to absorb carbon-14, so that the amount of the radiocarbon in its tissues steadily decreases.Our editors will review what you’ve submitted and determine whether to revise the article.
