Libby developed radiocarbon dating; for this, Libby was awarded the 1960 Nobel Prize in chemistry.

Depending on how measurements are made, organic remnants of plants and animals that lived upward of 60,000 years ago are datable.

The palace entryway appears in this reconstruction drawing, which shows Canaanites walking from the courtyard in the foreground, across a raised porch, toward the throne room entrance.

Maria Teresa Rubiato The recent discovery of massive jars of scorched wheat at Canaanite Tel Hazor may shed new light on the destruction of one of Israel’s most prominent sites.

The discovery of the 3,400 year-old wheat in a Late Bronze Age palace structure give a more complete image of the area’s agriculture before the destruction, and can help date the fire through carbon-14 analysis.

Radiocarbon dating of iron samples is, in spite of partially promising attempts in the last decades, still no established standard procedure.

One of the main problems in preparing iron is the low carbon content which makes the needed sample size too big for some sample combustion systems.

Also the metallic character of the samples complicates sample combustion or oxidation.This required in most cases an own preparation line only for iron samples.To avoid this problem two different ways are being followed at the Erlangen AMS-facility.One is direct sputtering of the unprocessed iron sample in the ion source.The other is the complete extraction of carbon from the iron sample and dating of the carbonaceous residue.First results from archaeological iron samples of known age, prepared and dated by these two methods, are presented and discussed.
