Carbon 14 Dating
Carbon-14 Dating: An Invaluable Yardstick in the Chronology of Humans

Archaeologists utilize several methods to analyze data from the past. One scientific tool helps to analyze the radioactive decay of chemical elements found in plant and animal remains, pottery, and even rocks. Radiocarbon dating, also known as carbon-14 dating, has developed into one of the most important radioisotope dating methods archaeologists employ. This scientific tool, first developed by Willard F. Libby in the late 1940s, began with the discovery of the isotopic carbon-14 atom. Following this discovery, scientists began to ponder ways to utilize carbon-14 to date previously living organisms. Since scientists knew that living organisms absorb carbon-14 at a constant rate while alive, they started to formulate a process to measure C-14 to C-12 ratios in dead organisms. This procedure made it possible for scientists to age an organism using this carbon ratio. To ensure the formula was correct, they began to perform experimental trials of radiocarbon dating to test its accuracy, and while testing, discovered several methods of carbon 14 dating that yielded accurate results including the Geiger counting method, liquid scintillation method, and AMS dating method. These three methods have significantly improved the accuracy of assigning dates to past events and artifacts, dating as far back as 70,000 years. Using and describing the techniques, procedures, and applications, the anthropological school of thought for carbon-14 dating will be derived. Although this method has drawbacks and critics, carbon-14 dating has shaped and influenced the historical classification artifacts to the point that archaeologists, geologists, and anthropologists now have the ability to construct the world’s history by filling in some of the many blank dates in the chronology of the history of our human world and by substantiating and revising other dates.
The foundation of radiocarbon dating began with

    2. Given that the half life of the radioisotope carbon -14 is 5730 years, it would not be useful in dating bones that are over a million years old. After 40 000 years of age less than 1% of the 14C is left in the bone and thus it is not useful for determining the exact age beyond that.…

    Potassium-Argon dating is a form of radiometric dating which tells us the absolute age of rocks. Practically all elements are radioactive to some extent, some more than others. Moreover, different isotopes of elements are more radioactive than others. Isotopes are forms of a particular atom that varies in the number of neutrons in the nucleus. For instance, K-40 is a naturally occurring isotope of Potassium is far more radioactive than its siblings K-39 and K-41 because K-40 is much less stable.…

    The field of landscape archaeology can be challenging in the way that it conducts itself. Most of the time the sites are obstructed by vegetation or they may be hidden in a farmer’s plowed field. However the surveying of these places do to their size and proximity to any adjacent constraints can often lead to poor performance of the archaeological standards. The sizes of these sites can sometimes be as large as settlements covering acres of land. However archaeologists have now been using a surveying method that employs the use of multi-instrument geophysical scanning. Using this the archaeologist can help maintain budget and time constraints that may have been restricting progress.…

    Charred wood from this feature was radiocarbon dated to sometime between 2010 B.C. and 1850 B.C. (more on this below). It had also been suggested that there may be a house foundation somewhere on the site which would more than likely date to the historic past (Wiegand, personal communication, 2002), and about 75 artifacts from the late 18th and 19th centuries, such as nails, redware, saltglazed stoneware, whiteware, and glass, most of which were found in the top 20 cm of soil, may support the idea that there was definitely such a structure on the site.

    Studying artifacts is like looking through a keyhole into the past. Although artifacts themselves cannot speak, a lot can be learned from studying primary documents and artifacts. For thousands of years, historians have been using primary documents and artifacts to make inferences about the people, places, and events that surrounded the time period. In our study of the Rixford Cemetry, we were able to use primary documents and artifacts to make analyses about the surrounding area.…

    With new studies that study the cooling of the earth, rate of volcanic ejecta, and growth of human population, one could assume that humans had a vast comprehension of Earth’s age, but this is not the case. Radiometric dating, when an element spontaneously changes into another element, is based upon the ability to determine the amount of product present in a sample. However, factors influence the radiometric age, thus making it difficult for a researcher to determine whether the system under study has remained closed. Only when several different radiometric isotope systems give the same date, then can it be a reliable…

    Otto Hahn was a German chemist who revolutionized the field of nuclear chemistry. Following a lifelong interest in chemistry, he found himself on the forefront of radiochemistry research in the early 20th century. Through a series of chance discoveries, he and his fellow researchers brought radiochemistry out of the realm of theoretical research and into actual practical science. One of the practical uses of this research led to the development of nuclear weapons. While Otto Hahn’s lifetime of education and research led to great contributions to chemistry, it also led to his dedication to using his powerful voice for social causes, especially to limit the threat of nuclear weapons.…

    Relative Dating

    For this lab, I decided to focus on relative dating in studying things of the past. I found this the most interesting form to examine. Relative dating doesn’t give one an exact date but can give a good time frame of an artifact. It is used by looking at sequences and layers with regards to the soil for excavating. This is known as stratigraphy (Bahn,122). It was inspired by geology in looking at layers of soil (Dating Archeology, 2016). As an archeologist using this method, one would say, “the underlying layer was deposited first and therefore, earlier then overlying layer”(Bahn, 122). In simple terms, the digger one deeps, the older it’s going to be for an artifact. This is the viewpoint of using relative dating. Once an artifact is found in a layer, the archeologist compares it to other artifacts.…

    “Radiometric age-dating is based on the fact that every radioactive element decays. The original or “parent” element emits radiation and particles until the loss thereof transforms it into a stable “daughter” element. A series of transformations into other radio-active elements marks its unparalleled pattern and rate of decay until it reaches stability (Think Quest).” “The decay of radioactive elements occurs at different rates, depending on the specific isotope. These rates are stated in terms of half-lives. One half-life is the amount of time required for ½ of the original atoms in a sample to decay (O'Neil).” Radiometric methods provide one of the most important ways to date fossils. The main types of radiometric dating are Potassium-argon, carbon-14 or radiocarbon, thermoluminescence, and electron-spin-resonance. Potassium-argon dating is used for dating volcanic rocks associated with fossil material. It can date better for older specimens but when used for younger specimens it can give a wrong date. You have to be careful and use the right method for the selected…
