It's accuracy has been verified by using C-14 to date artifacts whose age is known historically.The fluctuation of the amount of C-14 in the atmosphere over time adds a small uncertainty, but contamination by "modern carbon" such as decayed organic matter from soils poses a greater possibility for error. Thomas Seiler, a physicist from Germany, gave the presentation in Singapore.Because ancient Egyptian tombs are often well–sealed, archeologists have an unprecedented look at ancient makeup.For example, when King Tut’s tomb was opened in 1922, cosmetics were found inside that were still fragrant and perfectly usable.The ratio of radiocarbon to stable carbon atoms in the atmosphere has varied in the past.
