Books about radiocarbon dating

Although the number of carbon atoms varies from one organism to another, the proportion of carbon atoms to carbon atoms is basically constant — and roughly the same as the proportion found in the atmosphere. Carbon Copies Carbon dating begins, logically enough, with carbon. So for all practical purposes, carbon dating is useful only for samples up to about 50, years old though this depends somewhat on the mass of the sample — and some advanced techniques can reliably measure carbon levels low enough to indicate an age of , years. What did surprise me was the huge number of Web sites and books vigorously attacking the legitimacy of what I had thought was a fairly straightforward, uncontroversial test. When an organism dies, it stops acquiring new carbon atoms. Eventually, however, all the carbon atoms will decay — or at least enough of them will that the amount of radiation they emit can no longer be distinguished from ordinary background radiation. So I did a bit of research to fill in the gaps in my understanding, and not surprisingly I found the details to be quite interesting.

What did surprise me was the huge number of Web sites and books vigorously attacking the legitimacy of what I had thought was a fairly straightforward, uncontroversial test. Apparently carbon dating is right up there with evolution in terms of the disdain it evokes from certain religious groups. The result is that everything that is alive, or once was, contains some number of carbon atoms. Eventually, however, all the carbon atoms will decay — or at least enough of them will that the amount of radiation they emit can no longer be distinguished from ordinary background radiation. Carbon, along with the more common, stable nonradioactive carbon isotopes carbon and carbon, combine with oxygen to produce carbon dioxide. Carbon decays loses its radioactivity, converting back to nitrogen at a known rate; its half-life, or the time it takes for half a given number of carbon atoms to decay, is about 5, years. But I realized the other day that even as an adult with a fair amount of scientific knowledge, I could not articulate exactly how or why carbon dating works. So I did a bit of research to fill in the gaps in my understanding, and not surprisingly I found the details to be quite interesting. When an organism dies, it stops acquiring new carbon atoms. Animals, in turn, eat the plants or eat other animals that have eaten the plants , and thus the carbon atoms propagate throughout the food chain. So for all practical purposes, carbon dating is useful only for samples up to about 50, years old though this depends somewhat on the mass of the sample — and some advanced techniques can reliably measure carbon levels low enough to indicate an age of , years. Although the number of carbon atoms varies from one organism to another, the proportion of carbon atoms to carbon atoms is basically constant — and roughly the same as the proportion found in the atmosphere. Carbon Copies Carbon dating begins, logically enough, with carbon. So some of the residual carbon in plants is carbon As is often the case, the controversy over this topic is at least as interesting as the topic itself. For example, if a sample emits radiation indicating the presence of 10 carbon atoms and we know from its mass that it originally must have contained 20, that means the plant or animal from which the sample was taken died about 5, years ago.

  1. Carbon, along with the more common, stable nonradioactive carbon isotopes carbon and carbon, combine with oxygen to produce carbon dioxide. Animals, in turn, eat the plants or eat other animals that have eaten the plants , and thus the carbon atoms propagate throughout the food chain.

  2. So some of the residual carbon in plants is carbon For example, if a sample emits radiation indicating the presence of 10 carbon atoms and we know from its mass that it originally must have contained 20, that means the plant or animal from which the sample was taken died about 5, years ago.
