Carbon Dating Explained
Every living organism absorbs carbon 14, which ceases once it dies, leading to a gradual decline in its levels due to radioactive decay. By measuring the remaining carbon 14, scientists can estimate the age of organic materials, with a half-life of about 5,700 years. While this method is quite accurate, it has limitations, including its applicability only to organic matter and its effectiveness for items younger than 50,000 years. Notably, historical spikes in carbon 14 levels, such as those from nuclear testing in the 1950s, have influenced calibration methods.In this clip
