If someone can book the test for me, I will happily do it! But, the CIRC test, is only used to test people who's testosterone levels are absurdly high. This is because the CIRC test can diffentiate between natural testosterone and synthetic testosterone.

FOSSILS: how fossils are dated
 
04:05
Many times paleontologists will never know exactly how old a fossil is. Usually they guess its range or span of time. A good way of guessing the range is to look at the layers of rock that were formed by volcanoes. It's easier to guess the age of volcanic rock because it's brand new rock from the moment that it is spit onto the earth's surface.

Radiometric Dating is Flawed!! Really?? How Old IS the Earth?
 
10:18
THIS VIDEO IS LACED WITH SARCASM (to those who have difficulty sensing it). Scientists admit that radiometric dating, one of the fundamental techniques used to show the earth is billions of years old is flawed!!! The earth is not 4.55 billion years old. Watch and find out just how old it really is. Of course, scientists are always refining their techniques, it's part of of science works. Creationists have pointed to a number of "results" from radiometric dating that prove it doesn't work. Here I go over all the reasons why. Why is there Carbon-14 in some coal. Why did Potassium-Argon dating of the 1980 eruption of Mount Saint Helens give ages on the order of hundreds of thousands of years.

Carbon-14
 
11:35
Carbon-14, 14C, or radiocarbon, is a radioactive isotope of carbon with a nucleus containing 6 protons and 8 neutrons. Its presence in organic materials is the basis of the radiocarbon dating method pioneered by Willard Libby and colleagues (1949) to date archaeological, geological and hydrogeological samples. Carbon-14 was discovered on 27 February 1940, by Martin Kamen and Sam Ruben at the University of California Radiation Laboratory in Berkeley. Its existence had been suggested by Franz Kurie in 1934. There are three naturally occurring isotopes of carbon on Earth: 99% of the carbon is carbon-12, 1% is carbon-13, and carbon-14 occurs in trace amounts, i.e., making up about 1 part per trillion (0.0000000001%) of the carbon in the atmosphere. The half-life of carbon-14 is 5,730±40 years. Carbon-14 decays into nitrogen-14 through beta decay. The primary natural source of carbon-14 on Earth is cosmic ray action upon nitrogen in the atmosphere, and it is therefore a cosmogenic nuclide. However, open-air nuclear testing between 1955–1980 contributed to this pool. This video is targeted to blind users.

How Radiometric Dating Works: Relative not Absolute Ages
 
01:19:55
If you like this technical lecture from the 2017 IGH Conference, you can get it and over 70 more at: https://isgenesishistory.com/conference/ Listen to Dr. Andrew Snelling explain how radioisotope dating works, document the anomalies he has discovered with it, and examine how it can be used for relative dating purposes. Dr. Snelling completed a BS in applied geology at the University of New South Wales in Sydney, Australia, graduating with first-class honors in 1975. His PhD in geology was awarded in 1982 by The University of Sydney for his research thesis titled “A Geochemical Study of the Koongarra Uranium Deposit, Northern Territory, Australia.” Dr. Snelling worked for six years in the exploration and mining industries in Tasmania, New South Wales, Victoria, Western Australia, and the Northern Territory, variously as a field, mine, and research geologist. For over ten years, Dr. Snelling was a research consultant to the Australian Nuclear Science and Technology Organization for an international collaborative research project funded by the U.S. Department of Energy which involved university and government research scientists from the USA, UK, Australia, Japan, Korea, Sweden, Austria and Belgium. He is currently Director of Research for Answers in Genesis.

All living things are made up of about 25% carbon. The carbon atom is unique because it can bind to other carbon atoms to form long chains and rings and these in turn serve as the backbone of the complex molecules that make life possible. The nucleus of a typical carbon atom has 6 protons and 6 neutrons. But about one carbon atom out of every 100 has one extra neutron. This has very little effect on the properties of the carbon, other than making it slightly heavier. Chemically, it acts just like any other carbon atom. It is called Carbon-13. And there is an even rarer type of carbon. It is formed high in the atmosphere when cosmic rays strike atoms of nitrogen converting them into Carbon -14. Carbon-14 is also chemically identical to regular carbon. But the nucleus of carbon-14 is unstable. After some amount of time, which could range from a few days to many thousands of years, carbon-14 decays back into nitrogen. But since carbon-14 is formed at a steady rate, there is a constant level of it in the environment. Out of every trillion carbon atoms in your body, only one dozen of them are carbon-14. As long as an organism is alive and eating, it maintains a constant ratio of carbon-14 to regular carbon. But once an organism dies, the amount of carbon-14 in its body begins to decrease. After 5000 years about half of the original number of carbon-14 atoms will have decayed. Using this fact, scientists can tell how long ago an organism died. • http://www.cassiopeiaproject.com .

A video by the The Rafter Radiocarbon Laboratory NZ regarding carbon dating. Full article and more videos- http://www.eequalsmcsquared.auckland.ac.nz/sites/emc2/videos/cool-kiwi-science.cfm 'The Rafter Radiocarbon Laboratory has a long history in radiocarbon dating. To determine the radiocarbon age of an organic material it is necessary to measure the proportion of radiocarbon (C14) in the carbon that it contains. The technical problem to be solved is the detection of the rare isotope C14 in the presence of the much more abundant isotopes C12 and C13. The natural abundance of 14C is about one 14C atom per trillion (10^12) atoms of C12. What can you date? Anything containing carbon between 150 and 60,000 years old (i.e.: wood, leather, bone, paper, seawater, gases, ice cores, pollen, pottery, coral, seeds, charcoal, blood residues, sediment, soil, shell, textiles, plant and animal tissue, insect remains, cave paintings, resins and glues).' How it works Carbon-14 has half-life of 5730 years Natural abundance of C-14 is one C-14 atom to one trillion C-12 atomsSample is purified physically and chemically in the 'pre-treatment lab' Sample is burnt at 900C turning it into CO2 which is combined with hydrogen and passed over an iron catalyst. Result is pure carbon and water. Graphite carbon pellet is placed at one end of linear accelerator Carbon atoms are 'chipped off' graphite pellet and sent through acceleratorComputer counts the three different types of carbon atoms at other end of accelerator Ratio of carbon-12 and carbon-14 atoms indicates age of sample.

26. Isotope Evidence for Climate Change
 
47:23
The Atmosphere, the Ocean and Environmental Change (GG 140) Isotopes are used to measure past climate properties. Deuterium and oxygen 18 are the most commonly used climate proxies. Lighter isotopes evaporate more readily from the ocean, so water vapor in the atmosphere is isotopically lighter than ocean water. This vapor gets lighter still as it is transported to higher latitudes while losing mass by precipitation. These processes leave an isotopic signal of temperature and continental ice volume in ice cores and deep sea sediment cores. 00:00 - Chapter 1. Stable Isotopes of Water 09:48 - Chapter 2.

Carbon-14 Radioactive Dating Worked Example | Doc Physics
 
10:34
I'm thinking about getting back into dating. I'm only going to be seeing bits of cloth and broken plates, so there's no need to tell my wife. Besides - they're not what they used to be in terms of activity... Maybe I shouldn't put this on the internet. What, use restraint while posting to the web? Naah. It'll be fine. In other news, I hope this shows you how you can solve any radioactive dating problem from a very tiny amount of info. It's all related via some simple equations, so get familiar with them.

CHF acquires instrument that played a role in the development of carbon-14 dating.
 
04:20
CHF has acquired the "Libby Shield" from the National Urban Security Technology Laboratory (part of the Department of Homeland Security). The instrument played a key role in the development of carbon-14 dating. When Willard Libby received his Nobel Prize in 1960 for discovering the Radiocarbon dating process, the Nobel Committee asserted, "Seldom has a single discovery in chemistry had such an impact on the thinking in so many fields of human endeavor." Radiocarbon dating is a radiometric (or radioactive) dating technique that measures the amount of the naturally occurring (and radioactive) element Carbon 14. Scientists employ this method to determine the age of carbon-rich materials up to about 60,000 years. Libby initially hypothesized the existence of natural C-14 in the atmosphere in 1946. He first needed to demonstrate the presence of this natural Carbon 14 in living matter. In order to employ a Geiger Counter (a particle detector that determines whether objects emit nuclear radiation) that could accurately measure the radioactive Carbon 14 isotope, Libby needed a "shield" that would limit radioactive background noise, the naturally occurring radiation emitted by soil, groundwater, building materials, radioactive substances in the body and cosmic rays from outer space. Because its 12,000 lb. weight makes it too heavy for our museum, the Libby Shield is being stored in CHF's collections facility and will be made available for historical researchers.
Radiocarbon Dating
 
01:45
Radiocarbon Dating Dr. Michael Wilson, Geology Department, Douglas College "In the upper atmosphere, we have the conversion of 14nitrogen, stable nitrogen, into 14carbon which is an unstable isotope of carbon. That carbon circulates through the atmosphere, in carbon dioxide for the most part, and is taken in by organisms. Organisms at the earth’s surface, when they take in carbon, they are taking in the normal form of carbon, the stable form, which is 12carbon. They are also taking in 14carbon, and they are also taking in another isotope, 13carbon, which is relatively stable, too. So when we get a radiocarbon date, what we are trying to do is to convert the amount of 14carbon that we can measure in a sample into a date. So what’s going on here? The 14carbon is unstable, it’s a radioactive isotope, and over time it decays back through beta emission, it changes back to 14nitrogen and it’s lost. To compute a radiocarbon date then, we have to compute the amount of 14carbon that is present and compare it to the amount of 12carbon and 13carbon that are present in the sample and the ratio that we determine gives us an idea of how long it has taken for this ancient sample to change from the state that it had when it was alive. We take in 14carbon of course during life; we are always taking in 14carbon, so we maintain a fairly constant level of it in our body. As soon as we die, the 14carbon starts to die, so the ratio between the 12carbon, 13carbon and 14carbon is going to change. That’s the basis for our date. So that’s an absolute dating technique."
