Charcoal samples from Stonehenge in England were burned in the presence of oxygen with the resulting carbon dioxide gas bubbled into a solution of calcium hydroxide. The resulting precipitate of calcium carbonate was filtered and dried resulting in radioactivity measured as 0.0150 disintegrations per second from carbon-14 decay. Living organisms have a decay rate of 15.3 disintegrations per minute with a half-life of carbon-14 of 5715 years. Calculate the age of the original charcoal sample.
