How accurate carbon dating

30 Nov

For example, a steel spearhead cannot be carbon dated, so archaeologists might perform testing on the wooden shaft it was attached to.This provides good information, but it only indicates how long ago that piece of wood was cut from a living tree.

” question, as it will vary drastically from car to car, you’d have to be driving an incredibly unreliable car for it to incur a similar amount of carbon dioxide in repairs to the production of a brand-new car. Sticking with our Golf example, you could buy a brand-new Blue Motion 1.6 TDI, which emits just 85g/km.

That’s because the hidden cost to the environment of each new car is a stack of pollutants, a heap of waste and a whole lot of precious fossil fuel. The Carbon Footprint of Nearly Everything, Berners-Lee suggests that previous attempts to work out the carbon footprint of car production use a process-based approach – that is to say, to add up the carbon dioxide produced at each stage of a car’s production – but that this approach will always result in an underestimate.

He suggests that use of the input-output method, in which one takes account of the carbon dioxide emitted by the various industries that contribute to the manufacture of that car, gives a more accurate picture, even if it does rely heavily on the law of averages.

Question: "Is carbon dating a reliable method for determining the age of things?

" Answer: Carbon dating, or radiocarbon dating, like any other laboratory testing technique, can be extremely reliable, so long as all of the variables involved are controlled and understood.
