Practical uses of carbon dating

Sodium chloride containing sodium-24, can be injected into the bloodstream to study blood circulation.The beta particles emitted by the sodium-24 are followed and an impaired circulation is immediately detected.Their research provides a new method for determining ...

The rate of iodine-131 uptake, determined with a Geiger counter or other scanning device, indicates whether the thyroid glands are functioning properly.They have been employed in study of gastric emptying, liver function, fat absorption, P450 mixed-function oxidase, bacterial overgrowth, oro-caecal transit time, etc.Iso-Analytical provides a comprehensive mass spectrometry service for carbon-13 breath test samples and also can offer help in experimental design and data interpretation.Thus whilst advanced liver disease can be diagnosed with confidence, early or marginal hepatic disease is poorly defined.To increase this definition a series of breath tests have been developed and refined over the last 20 years.The radioactive element americium has a half-life of 432 years, and is a good source of alpha particles.Another way to talk about the amount of americium in the detector is to say that a typical detector contains 0.9 microcurie of americium-241. If you are holding a curie of something in your hand, you are holding an amount of material that undergoes 37,000,000,000 nuclear transformations per second.Fossil corals have the unique advantage that they ...— Using the largest set of radiocarbon dates ever obtained from a single Maya site, a team of archaeologists have developed a high-precision chronology that sheds new light on patterns leading up to ...Food irradiation is a method of treating food in order to make it safer to eat and have a longer shelf life.This process is not very different from other treatments such as pesticide application, canning, freezing and drying.
