Is carbon dating reliable

Carbon dating has the peculiar property that it works primarily on dead things.

Other forms of radioactive dating are more broadly applicable. If so, the official definition is "the determination of the age or date of organic matter from the relative proportions of the carbon isotopes carbon-12 and carbon-14 that it contains".

Volcanic ejecta of Mount Rangitoto (Auckland, New Zealand) was found to have a potassium-40 age of 485,000 years, yet trees buried within the volcanic material were dated with the carbon-14 method to be less than 300 years old.

A further example from a lava flow off the coast of Hawaii shows similar discrepancies.

Accurate carbon dating requires specialized and extremely expensive equipment to measure the ratio of carbon 13-carbon 14.

Carbon dating uses the carbon-14 isotope, with a half life of about 5700 years.For carbon dating, the isotope used is Carbon-14, which has a half life of 5,700 years..pass_color_to_child_links a.u-inline.u-margin-left--xs.u-margin-right--sm.u-padding-left--xs.u-padding-right--xs.u-absolute.u-absolute--center.u-width--100.u-flex-align-self--center.u-flex-justify--between.u-serif-font-main--regular.js-wf-loaded .u-serif-font-main--regular.amp-page .u-serif-font-main--regular.u-border-radius--ellipse.u-hover-bg--black-transparent.web_page .u-hover-bg--black-transparent:hover. 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 the radio-activity of Carbon 14 which is unstable so it emits protons once in a while in order to become a more stable isotope.Carbon dating is not perfect, but it can give you a rough idea. Using Carbon dating, we can determine with accuracy how old something is.

This requires that only the parent isotope be initially present or that the amount of daughter isotope present at the beginning is known so that it can be subtracted.
