Short notes on radiocarbon dating

Humic and fulvic acids are naturally present in soil where microbial degradation of plants and animals has occurred.

The effect of these organic acids on the sample, whether they would make the sample older or younger, depends on the age of their original organism.

Bones, shells, wood, charcoal, peat, linen, wool, and parchment are the common materials submitted for radiocarbon testing.

Metal and stones cannot be directly dated unless they have organic materials embedded in them.

Radio carbon dating is only possible with the materials that were once associated with living things.

Thus age of inorganic materials cannot be determined by this methods like stone etc.

There is no standard method for pretreatment applicable to all samples for radiocarbon dating.

One of the basic assumptions in carbon-14 dating is that the sample being analyzed has undergone only radioactive decay and has remained unaltered by any other process over the years since it ceased interaction with the biosphere. The archaeological artifacts and geological specimens sent to labs for radiocarbon dating are usually found embedded or buried with other materials that may have affected their radiocarbon content.

Radio carbon dating is a technique of finding out the age of organic matters like fossils, wood, leather etc.

by comparing the amount of radio carbon present in them.

The specific effect of the contaminant on radiocarbon dating results depends on the type of contaminant, the degree of contamination, and the relative ages of the sample and the contaminant.

Limestone is of geological origin and would be much older than any archaeological sample; hence, inclusion of limestone during the carbon 14 dating would make the sample older than its true age.

  1. Marriage in Islam is a beautiful way for two people to bring together their families, heritage and culture for the purpose of bringing more little Muslims into the world, in love, commitment and dedication to Allah, His Book, His prophet, peace be upon him, and surrender to Him in peace (Islam).
