The Radiocarbon Dating Laboratory in Lund performs dating on geological and archaeological samples. Examples of material that we date are wood, charcoal, peat, macrofossils, bone and marine shells. Natural 14CĀ can be used in numerous applications, of which radiocarbon dating, with the possibility for dating back to about years, is among the best-known and most practiced applications. Radiocarbon dating is based on the property that the activity concentration of 14C in dead tissues can be used to calculate the time that has elapsed since death occurred. This is possible since all living organisms contain nearly the same proportion of radioactive carbon in their carbon stores and since, upon the death of the organism, the carbon which survives decomposition continuously loses 14C by its radioactive decay. Basic price The basic price is SEK excl. VAT for one normalĀ 14C-dating.
