Radiometric Dating: Methods, Uses & the Significance of Half-Life

The United States is committed to promoting and protecting human rights. In the words of President Barack H. By no means is America perfect. But it is our commitment to certain universal values which allows us to correct our imperfections, to improve constantly, and to grow stronger over time. Freedom of speech and assembly has allowed women, and minorities, and workers to protest for full and equal rights at a time when they were denied. The rule of law and equal administration of justice has busted monopolies, shut down political machines that were corrupt, ended abuses of power. Independent media have exposed corruption at all levels of business and government. Competitive elections allow us to change course and hold our leaders accountable. If our democracy did not advance those rights, then I, as a person of African ancestry, wouldn’t be able to address you as an American citizen, much less a President.

Uranium–uranium dating is a radiometric dating technique which compares two isotopes of uranium (U) in a sample: uranium ( U) and uranium ( U). It is one of several radiometric dating techniques exploiting the uranium radioactive decay series, in which U undergoes 14 alpha and beta decay events on the way to the stable isotope Pb.

It is science, though many times confused as being the same thing. I’ll prove my point. You know that I could never have been inside of your mysterious building out there, and I imagine you can be sure no one has told me its secrets. Yet I’ll bet that I can describe fairly accurately what is in there—not from seeing the machinery, but from knowing what must be done to oil in order to get the products you need.

You want to hear? Your crude oil runs into a tank of some kind, and you pipe it from there to a retort , some big vessel that you can seal airtight. Once it is closed, you light a fire under the thing and try to get all the oil to an even temperature. A gas rises from the oil and you take it off through a pipe and run it through a condenser , probably more pipe with water running over it. Only my family have seen, no others—I’ll swear to that! I told you that we have been doing this stuff for years in my country.

I’m not out to steal your secrets. In fact, they are pretty small potatoes where I come from, where every farmer has a still for cooking up his own mash and saving on taxes. I’ll bet I can even put in some improvements for you, sight unseen. How do you monitor the temperature on your cooking brew?

Uranium-lead dating uses four different isotopes to find the age of the rock. The four isotopes are uranium , uranium, lead , and lead The process of dating finds the two ratios between uranium and lead; and uranium and lead

This is what archaeologists use to determine the age of human-made artifacts. But carbon dating won’t work on dinosaur bones. The half-life of carbon is only 5, years, so carbon dating is only effective on samples that are less than 50, years old. Dinosaur bones, on the other hand, are millions of years old — some fossils are billions of years old. To determine the ages of these specimens, scientists need an isotope with a very long half-life. Some of the isotopes used for this purpose are uranium , uranium and potassium , each of which has a half-life of more than a million years.

Unfortunately, these elements don’t exist in dinosaur fossils themselves. Each of them typically exists in igneous rock, or rock made from cooled magma. Fossils, however, form in sedimentary rock — sediment quickly covers a dinosaur’s body, and the sediment and the bones gradually turn into rock. But this sediment doesn’t typically include the necessary isotopes in measurable amounts. Fossils can’t form in the igneous rock that usually does contain the isotopes.

Decay routes[ edit ] The above uranium to lead decay routes occur via a series of alpha and beta decays, in which U with daughter nuclides undergo total eight alpha and six beta decays whereas U with daughters only experience seven alpha and four beta decays. The term U—Pb dating normally implies the coupled use of both decay schemes in the ‘concordia diagram’ see below.

However, use of a single decay scheme usually U to Pb leads to the U—Pb isochron dating method, analogous to the rubidium—strontium dating method. Finally, ages can also be determined from the U—Pb system by analysis of Pb isotope ratios alone. This is termed the lead—lead dating method. Clair Cameron Patterson , an American geochemist who pioneered studies of uranium—lead radiometric dating methods, is famous for having used it to obtain one of the earliest estimates of the age of the Earth.

Share by Mail The question of the meaning and proper interpretation of the early chapters of Genesis is one of the most heated subjects in Christendom today. Few other topics have evoked such polarised opinion and division. The diversity of views on Genesis, even among the most learned of exegetes and scholars, is staggering. While one extreme insists that the days of Genesis must strictly be interpreted as seven consecutive hour periods thus rendering the earth very young indeed — in the order of thousands, and not millions or billions, of years old , at the other extreme lies the notion that the early chapters of Genesis are devoid of any historical content at all.

There is a plethora of competing views which reside in the middle of those polar extremes: In this article, I attempt to show that, while it is possible to interpret the book of Genesis in light of a young earth, there is no Biblical mandate for this conclusion: That is to say, Genesis could be interpreted in that manner, but it does not have to be. And, as a scientist, the arguments for an ancient earth seem to be very compelling needless to say, when it comes to Darwinian evolution, it is a very different story.

Having shown that Genesis does not require that one read it as conveying a young earth, I hope that readers will be convinced that we can thus read and understand the science on its own terms as well.

The nucleus contains two fewer protons and two fewer neutrons. Beta 1 electron One neutron decays to form a proton and an electron, which is emitted. If an element decays by losing an alpha particle, it will lose 2 protons and 2 neutrons. If an atom decays by losing a beta particle, it loses just one electron. So what does this have to do with the age of Earth?

Radioactive decay eventually results in the formation of stable daughter products.

These techniques, unlike carbon dating, mostly use the relative concentrations of parent and daughter products in radioactive decay chains. For example, potassium decays to argon; uranium decays to lead via other elements like radium; uranium decays to lead; rubidium decays to strontium; etc.

All Your efforts and writings are so clear and result in easy to understand reading. Your work is indeed very important!!!! Your search for truth and justice is very much appreciated. You deserve a purple heart for bravery, and a Pulitzer prize for work that is so distinguished! In particular I am awed by and profoundly grateful for your persistence and determination in the face of the persecution you have endured in the process.

Radiometric Dating

These are K-Ar data obtained on glauconite, a potassium-bearing clay mineral that forms in some marine sediment. Woodmorappe fails to mention, however, that these data were obtained as part of a controlled experiment to test, on samples of known age, the applicability of the K-Ar method to glauconite and to illite, another clay mineral. He also neglects to mention that most of the 89 K-Ar ages reported in their study agree very well with the expected ages.

Evernden and others 43 found that these clay minerals are extremely susceptible to argon loss when heated even slightly, such as occurs when sedimentary rocks are deeply buried.

See this page in: Hungarian , Russian , Spanish People who ask about carbon 14C dating usually want to know about the radiometric [1] dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years. People wonder how millions of years could be squeezed into the biblical account of history. Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering —the reason Jesus came into the world See Six Days?

Christians , by definition, take the statements of Jesus Christ seriously. This only makes sense with a time-line beginning with the creation week thousands of years ago. It makes no sense at all if man appeared at the end of billions of years.

Physics[ edit ] In Darwin’s time, physical scientists such as William Thomson performed calculations on physical processes such as the cooling of the Earth and the burning of chemical fuel by the sun. They concluded that the Earth might only be tens of millions of years old. These estimates, based on seemingly irrefutable physical principles deeply troubled Darwin.

What are some Advantages and Disadvantages of Theocracy? First we must understand what a theocracy is. Thearchy or theocracy is government by the immediate direction of God though his ministers and representatives. When Christ comes to reign personally on the earth during the millennial era, a perfect theocratic government will prevail. T…his perfect system of government was set up by Adam, and to a great extent by Abraham, Isaac and Jacob.

Certainly ancient Israel in the days of Moses and the judges operated on a theocratic basis. Man cannot operate such a government unless it is under the direction of God. All governments today are far removed from God and rely on their own wisdom. Discuss the advantages and disadvantages of globalization to small scale industries in India.
