Accordingly, carbon dating carefully applied to items from historical times can be useful such as physics, chemistry, molecular biology, physiology, etc . Carbon dating standards the radiocarbon age of a certain sample of unknown age can be determined by measuring its carbon 14 content and comparing the result to the carbon 14 activity in modern and background samples. Radioactive dating because the radioactive half-life of a given radioisotope is not affected by temperature, physical or chemical state, or any other influence of the environment outside the nucleus save direct particle interactions with the nucleus, then radioactive samples continue to decay at a predictable rate. Physics of carbon dating carbon has unique properties that are essential for life on earth familiar to us as the black substance in charred wood, as diamonds, and the graphite in “lead” pencils, carbon comes in several forms, or isotopes.
