By other non-scientific estimates I'd put it to years old. Would it be possible to use Radiocarbon C14 dating to get a good estimate?
I've seen C-dating used for ancient samples BC etc. Of course, one must assume the wood was used not too long after it was cut down I suppose. Sample amount is not a problem: This question does not appear to be about physics within the scope defined in the help center.

If this question can be reworded to fit the rules in the help centerplease edit the question. This is enough information to calculate the age of any organic, or living material, up to an age of around 40 to 50 years i. For your situation, all that is known is the half-life of carbon Hope this helps, I know I've repeated things that you know but in case there's anything you missed.

So far as the principle goes there shouldn't be any trouble right? Of course, you'll only get the time when the wood was cut, and not when the house was finished construction. However, you could ask a construction worker or something related to construction to estimate how long your house would have taken to construct.
Radiocarbon dating is a method...
Very closely related to physics. Limitations of the methods: Carbon dating is calibrated using data from tree rings.
For example, a steel spearhead...
For example, if you cut down an old tree today, you can see the growth rings going back many years. You can then carbon date each ring and use the data to calibrate other readings. You can do this further back than the lifetime of any current tree by matching the patterns of overlapping older samples. If you have sufficient local samples you can be very accurate.
In your case, since your samples are trees, if you have a big enough sample and a good local database, you might get the actual year that the tree was cut. The basic formulae that are required for radioisotopes and nuclear half-life: Any thoughts on what accuracy I may expect at a year sample? A recent study by the National Institute of Justice showed that the accuracy of carbon dating on human remains from the past 60 years had an error of about 3 years.
Until probably years, that error of 1.

That being said, I'd expect a year old sample to have an error of around 3 to 10 years. Your analysis naively assumes that the natural radioactive carbon doesn't vary: Yes, I completely agree with you, Rob Jeffries.
Without understanding the mechanics of...
However, I assumed that this would be like a question you'd receive in a test. In that context, my analysis should be correct.
Is it accurate? Response: I asked several people who know about this field. Their responses are numbered below.
(1.) C14 dating is very accurate for wood used. Without understanding the mechanics of it, we put our blind faith in the words of scientists, who assure us that carbon dating is a reliable.
Radiocarbon dating also referred to when carbon dating or carbon dating is a method for determining the age of an point containing organic material by using the properties of radiocarbon Normal, a radioactive isotope of carbon. The method was developed popular the late s by Willard Libby , who received the Nobel Prize in Chemistry appropriate for his work in It is based on the certainty that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen.
The resulting 14 C combines with atmospheric oxygen to be composed of radioactive carbon dioxide , which is incorporated into plants not later than photosynthesis ; animals then buy 14 C by eating the plants. When the animal otherwise plant dies, it stops exchanging carbon with its environment, along with from that point onwards the amount of 14 C it contains begins to decrease seeing that the 14 C undergoes radioactive decay.
Measuring the amount of 14 C in a experience from a dead plant before animal such as a tune of wood or a piece of bone provides information with the aim of can be used to assess when the animal or position died. The older a representation is, the less 14 C there is to be detected, and because the half-life of 14 C the period of time after which half of a given sample will own decayed is about 5, years, the oldest dates that preserve be reliably measured by that process date to around 50, years ago, although special grounding methods occasionally permit accurate breakdown of older samples.
Research has been ongoing since the s to determine what the share of 14 C in the atmosphere has been over the past fifty thousand years. The resulting data, in the approach of a calibration curve, is now used to convert a given measurement of radiocarbon hip a sample into an price of the sample's calendar Other corrections must be made to account for the share of 14 C in several types of organisms fractionation Prescribed, and the varying levels of 14 C throughout the biosphere reservoir effects.
Additional complications happen from the burning of vestige fuels such as coal along with oil, and from the in the air nuclear tests done in the s and s. Because the time it takes to catechumen biological materials to fossil fuels is substantially longer than the time it takes for its 14 C to decay inferior detectable levels, fossil fuels embrace almost no 14 C Ordinance, and as a result at hand was a noticeable drop here the proportion of 14 C in the atmosphere beginning here the late 19th century.

You have a feeling a guy likes you. How do you react? We know the exact half-life of carbon, so carbon dating is extremely should not have been selected as a tool in which to date the wood. 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..

By measuring the rate of production and of decay both eminently quantifiable , scientists were able to estimate that carbon in the atmosphere would go from zero to equilibrium in 30, — 50, years. There are several other possible sources of error that need to be considered. This is the reverse of the way the curve is constructed: A 14 C signal from the process blank measures the amount of contamination introduced during the preparation of the sample.
