Carbon dating used scientists

Because of the short length of the carbon-14 half-life, carbon dating is only accurate for items that are thousands to tens of thousands of years old. Geologists must therefore use elements with longer half-lives.For instance, potassium-40 decaying to argon has a half-life of 1.26 billion years and beryllium-10 decaying to boron has a half-life of 1.52 million years.Carbon dating is a method of telling approximately how old an ancient object is. The scientists used carbon dating and decided that the mummy was 10,000 years old.Carbon dating is not perfect, but it can give you a rough idea. Scientific Methods such as Radio Carbon Dating allow archaeologists to pinpoint the time from which their discoveries are from, it is especially helpful in terms of human remains.When it has decayed by half it is known as a half-life.They can calculate how many half-lives have passed and then find the age of the artifact!

How do scientists know how old an object or human remains are?Carbon dating is used by archeologists to date trees, plants, and animal remains; as well as human artifacts made from wood and leather; because these items are generally younger than 50,000 years.Carbon is found in different forms in the environment – mainly in the stable form of carbon-12 and the unstable form of carbon-14.Carbon-14 has a half life of 5730 years, meaning that 5730 years after an organism dies, half of its carbon-14 atoms have decayed to nitrogen atoms.Similarly, 11460 years after an organism dies, only one quarter of its original carbon-14 atoms are still around.
