Carbon Dating

The photons are then tracked by a tomographic scintillation counter, and the information is processed by a computer to provide both image and data on blood flow and metabolic processes within bodily tissues. PET scans are particularly useful for diagnosing brain tumor and the effects of strokes on the brain, along with various mental illnesses. They are also used in brain research and in mapping of brain functions.

In both X-rays and CT scans, a form of radiation is emitted and travels through the body, and a detector receives the unabsorbed rays and transmits them to a computer. The physics behind PET scanning is quite different. Basically, a person is injected with a radioactive substance. This substance begins the process of

Encyclopaedia Britannica also states that it is “proved to be a versatile technique of dating fossils and archaeological specimens from 500 to 50,000 years old” (1998). This method of age determination is dependent upon the decay of nitrogen and radiocarbon (Carbon-14) (Encyclopaediea Britannica, 1998; Opinions of Radiocarbon Dating, 2011). Carbon-14 is continually formed in nature by the interaction of neutrons with nitrogen-14 in the Earth’s atmosphere (Encyclopaediea Britannica, 1998; Opinions of Radiocarbon Dating, 2011) and all living things exchange the gas carbon-14 with the atmosphere surrounding them. The amount of carbon-14 exchanged into the living organism is perfectly balanced with its surroundings, but when an organism dies, they stop taking in the gas and that equilibrium is damaged. Because Carbon-14 slowly decays at a known rate called its “half-life” in a dead organism, scientists can figure out how long ago it had stopped exchanging carbon with its atmosphere. Thus, its age can be determined by measuring the amount of Carbon-14 in a sample (Hirst, 2017; Opinions of Radiocarbon Dating, 2017; Oxford Radiocarbon Accelerator Unit Research Laboratory for Archaeology, n.d.; Earthsky, 2017; Cram, 1993). With the utilisation of Radiocarbon Dating, scientists have been able to discover that Lindow

2) Carbon -14 would not be effective at dating bones that are millions of years old. Carbon -14 is effective at dating to a maximum of 40 000 to 50 000 years old. The isotope decays over time and would not be present on bones that are millions of years old.

During the last decade, major progress has been made in the treatment of disease with radioisotopes. Treatments involving the use of medical isotopes are gaining momentum in the race against many types of cancer. FDA approved and highly promising therapies are doubling every 3 to 4 years. Some researchers predict that over 80% of cancer types should be treatable with

They do this by comparing the tree rings and dating them to the calendar year in which they were formed. By matching the patterns (crossdating) the ring growth of different trees, scientists are able to assign the rings to specific dates. Crossdating can even be achieved in spite of the human interference to the tree ring growths and other factors such as extreme weather conditions. Overall dendrochronology is a very accurate technique where determination of absolute dates to year is either theoretically or practically possible.

The second method, used by Donahue, Olin, and Harbottle in their testing of the Vinland Map is radiocarbon dating (Donahue, Olin, Harbottle, 2000). Radiocarbon dating is based on the decay of a specific carbon isotope known as 14C. All organisms contain 14C and once an organism dies, scientists are able to measure how much 14C has decayed in an organism. By measuring this rate of decay, scientists are able to date the age of an organism (Higham). Since the Vinland Map is drawn on

A half life lab was conducted by rolling pennies in a cup, and then setting aside those which were heads down. This process represents a half-life of the atom, or the time required for half of a substance sample to decay. The purpose of performing this lab was to simulate the transformation of a radioisotope over time, and to graph the data in a way that relates it to radioactive decay and half-lives. The presumed result of this experiment was that a little less than half the pennies would be face down due to some inconsistencies when shaking and pouring the pennies out of the cup.

In 1947 Clair "Pat" Patterson began to calculate the age of the Earth by the request of Harrison Brown at the University of Chicago. The age of the Earth was always questionable to historians before Pat Patterson. In 1650 James Usher Archbishop of Ireland accepted biblical views as authoritative and used events from the old testament to calculate the age of the Earth. His calculations gave him the result of Saturday October 22, 4004 B.C. at six o' clock P.M. Scientists after that began to try and measure the sediments of rock in the Earth but their calculations varied too widely from three million to fifteen billion years. It was then discovered that by calculating the amount of lead in meteorites you will be able to see exactly how old the Earth really is.

If a tree falls in a forest and no one is around to hear it, does it still make a sound? If God created the earth and no one was around to see it, did it still happen? The answer to both of these questions is yes. Because of the Bible, we know that God created the earth in a literal 6, 24 hour days about 6,000 years ago. Many Christian think God may have used evolution and creation but that is not a viable theory. Methods such as Carbon Dating cannot be trusted because they have been proven inaccurate over and over again. Because radiocarbon dating is inaccurate, the literal Genesis account of creation is the one and only viable answer to where this world came from.

What is radiocarbon dating? “Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon (14C), a radioactive isotope of carbon.” (Wikipedia) Scientists have determined the Age of the Earth to be four point five hundred and forty-three billion years old. But, Red platelets and hemoglobin have been found in a few unfossilized dinosaur bone. Be that as it may, these couldn't last more than a couple of thousand years—surely not the 65 million years from when evolutionists think the last dinosaur lived. Helium is filling the climate from radioactive rot, however very little is getting away. In any case, the aggregate sum in the environment is just 1/2000 of that normal if the air were truly billions of years old. This helium initially got away from rocks. This happens entirely quickly, yet so much helium is still in some stones that it couldn't have had sufficient energy to get away. Of course nothing can be proven for sure and many creation scientists know this. But many of the modern dating methods depend on unprovable

Rocks have been a record that shows that the world is 4.5 billion years old; although the first 500 million years of earth has not been recorded by rocks some of earths life has. (Condie) Rocks are used for scientists to discover and hypothesize the origins of earth and to form theories about how life and the way land masses were created.

Olson emphasized on the advancement of medicine from the use of leeches and bleeding people to relieve them of evil humor to the current use of modern machines, such as the CT and Positron Emission Tomography (PET) scan. Olson explained that while modern medicine is fascinated with the CT scan, there are other technology such as the PET scan that can provide even greater detail than the CT scan. Using the CT scan in combination with PET scan can allow radiologist to differentiate between a mass, which is visible under CT scan or a specific tumor, which can be seen using a PET scan (Olson). Based on the information provided by Olson “a PET scan can show the level of a tumor. It can be used for diagnosing Alzheimer's disease and some heart diseases. Combined with the CT scan, it's tremendously valuable"

Radioactivity has been around since the 1800s. It is very popular in the medical field. It is used my many professionals to help diagnose and treat people every single day. Although it does have some advantages and disadvantages, people still use it to this day.

This changed history forever. While it created controversy, due to some people’s attachments to the old ways of dating and doubts in this revolutionary method, it proved to be the closest method to have an accurate chronology of history. In 1955, to prove the accuracy or radiocarbon, Libby published a graph that showed the comparison of the results of radiocarbon dating of specimens from Egypt. These specimens had already an absolute known date. The graph proved the accuracy of Libby’s radiocarbon dating. Figure 1 (Renfrew, 1973)
