Carbon 14 Dating Problems  - Nuclear Chemistry & Radioactive Decay
This nuclear chemistry video tutorial explains how to solve carbon-14 dating problems. It discusses how to estimate the age of an expired piece of wood based on the radioactive decay of the C-14 isotope which undergoes beta decay. It discusses how to use two formulas given the carbon-14 decay rate in counts per minute per gram to estimate the age of the sample. This video contains plenty of examples and practice problems.

Radiometric Dating is Flawed!! Really?? How Old IS the Earth?
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.

Half-Life and Radioactive Decay
136 - Half-Life and Radioactive Decay In this video Paul Andersen explains how a radioactive nuclei can decay by releasing an alpha, beta, or gamma particle. The exact moment of decay for each nuclei can not be determined but probability is useful in predicting the half-life. The half-life is the amount of time required for half of the radioactive nuclei to decays and depends on the decay constant. Several examples of decay and several half-lives are included.

How to Do Half-Life Problems of Radioactive Isotopes
How to solve half-life problems http://chemin10.com Determine the half-life of a radioactive isotope, the time taken to fall to half its original value. What is the half-life of an isotope and how to do half-problems. This lesson covers how to solve half-life problems, including solving for the half-life of a radioactive isotope, determining the amount remaining after a specified amount of time has passed, the original amount present, and the amount of time that has passed, the latter of which is used to determining the age of a fossil using carbon-14 dating. In this chemistry lesson, you will learn:  how to read an exponential decay curve  the half-life equation  how to solve for amount of radioactive isotope remaining  how to determine the half-life of an isotope  how to determine the amount of time that has passed, given an initial and final amount of radioactive sample And solve these sample problems: The half-life of Zn-71 is 2.4 minutes. If one had 100.0 g at the beginning, how many grams would be left after 7.2 minutes has elapsed? Pd-100 has a half-life of 3.6 days. If one had 6.02 x 1023 atoms at the start, how many atoms would be present after 23.0 days? How many years will it take for 84.0 grams of tritium to decay to a 23.5 gram sample? (The half-life of tritium is 12.3 years.) You can learn more about how to find half-life of an isotope by visiting: http://www.chemteam.info/Radioactivity/Radioactivity-Half-Life.html To learn about radioactive decay, namely, alpha, beta and gamma decay, watch my video here: https://youtu.be/4FuvyIDM_eQ?list=PLQg9Ykih483GIlw7XGkZyuUT5Wi5YtRvS This video is created by an experienced Chemistry teacher for high school students who are looking to learn more about how to do half-life problems.

Secular Equilibrium in Radioactive Decay Chains -- Part 1
Secular equilibrium is the state in which all radioactive decay chain products have accumulated to their respective equilibrium amounts, so that each nuclide decays at the same rate as the original ancestor nuclide. This is state of any uranium ore rock that has been undisturbed over geological ages. Secular equilibrium is easy to understand if you use a dripping container model to represent each unstable product in the decay chain. Each container fills up to the level at which the rate of production exactly matches the rate of decay. When all containers in the chain reach their own equilibrium levels, the whole chain is in secular equilibrium. Part 2 of the presentation (https://youtu.be/OZtkb120HnI) explains how the amount of water accumulated in each container is related to the container's half-life. From this, you can determine the exact amount of each nuclide that exists in the uranium-bearing rock sample. Here are some useful links for additional information about secular equilibrium and radioactive decay: Secular Equilibrium in Radioactive Decay Chains (website) http://ataridogdaze.com/science/secular-equilibrium.html Difference Between Half-Life and Average Life, with Problem Examples http://ataridogdaze.com/science/half-life.html Calculation of Decay Activity of One Gram of Natural Uranium http://ataridogdaze.com/science/uranium-decay-rate.html Carbon-14 and Radiocarbon Dating http://ataridogdaze.com/science/carbon-14.html Origin of Atmospheric Argon http://ataridogdaze.com/science/potassium40-to-argon40.html Note: To make this presentation more user-friendly to non-technical viewers, I avoided using the term "Becquerels" (abbreviation: Bq), which means simply "atoms per second". Therefore, 1 gram of U-238 decays at a rate of 12,000 Bq or 12 kBq. Is Secular Equilibrium the Same as True Equilibrium? No, the amounts of the nuclides at the two ends of the chain are not constant. At the top of the chain, the U-238 is disappearing at a rate of 12,000 atoms per second. At the bottom of the chain, stable lead-206 is accumulating at 12,000 atoms per second. So this is not true equilibrium. However, secular equilibrium means no change over the ages. When dinosaurs roamed the earth 65 million years ago, the U-238 in this rock was decaying at 12,000 atoms per second, just as it is now. The amount of U-238 decreased by only 1% over that period of time. So you can see that during the existence of humans, and even recent geological history, the decay rate can be considered constant.

Uranium 238   My story
Depleted uranium (DU) is obtained by processing mined uranium ore. Most of the radioactive isotopes extracted from the ore are used for nuclear weapons or atomic power plants. What remains is a less radioactive isotopeto 238, ie depleted uranium. It is almost two times denser than lead and flammable at impact, which makes it extremely effective when penetrating the armour. Miltary experts have in 1970s started to embed DU into the nozzles of conventional nuclear projectiles, granades and bullets. Every projectile contains about 350 grams of DU and that part of the projectile is called a “penetrator”. When a uranium “penetrator” hits a tank, the “penetrator” and the armour partially soften under the pressure. According to Pentagon’s literal description, a depleted uranium projectile goes through a tank like “a hot knife through butter”. There are disagreements about the scale of danger that DU poses. Experts agree that toxic and radiological risk is increased by DU’s property to split into fine dust that remains in the nature or in the human body for a very long time. “Only one particle of DU in the lymph glands can destroy the whole immune system”, said doctor Rodger Coghill at the London conference dedicated to the connection between DU and cancer diseases in Iraq.

This is an overview presentation of Dr. Walt Brown's online chapter on radioactivity's origin on earth. The information in this presentation shows the problems with using radiometric decay as an indicator of earth's age. This is based on his hydroplate theory of how the earth experienced a global flood as described in Genesis 6-9 (the flood of Noah). For more information about this subject and the hydroplate theory visit the Center for Scientific Creation website at: www.creationscience.com/onlinebook, key words hydroplate theory, Walt Brown, radioactivity, radiometric decay, old earth, age of the earth, zircons, uranium, radiometric lead, U238, Pb206, origins, catastrophic, plate, tectonics, lightning, hydro, plate, proton, neutron, super heavy elements, Bill Maher and Bill Nye should study hydroplate theory before declaring the Flood of Noah to be a children's fairytale.

Alpha, Beta and Gamma Rays | Hindi
The nucleus of radioactive material, emits three different types of radiation rays called alpha, beta and gamma. Alpha rays carry particles originating from the nucleus of a radioactive atom. These particles consist of two protons and two neutrons. Beta rays are a stream of negatively charged electrons. Gamma rays are pure energy. Because a gamma ray has neither mass nor charge, it remains unaffected by the magnetic field.

Why Dating Methods Can Date Nothing
Radiometric dating methods rely upon circular logic, such as calibration curves and dating fossils by rocks by strata by fossils by rocks by strata. When employing dating methods, evolutionists toss out dates which dissagree with the assumed age of something only to publish the date that seems to come closest to their assumption. You are never told about the dates which dissagreee with their assumptions. They are not scientific and ignora several scientific observations which make it clear that they are worthless. The Unikaret lava formation near the bottom of the Grand Canyon has been dated at 10,000 YA 117 MYA 1.39 BYA 2.6 BYA 853 MYA 1.1 BYA 715 MYA The University of Arizona has discovered Native American tools have been found in the lava Unikaret lava formation, which they state were put there between 800-1,000 yrs old. Samples from the 1986 dacite flow on Mount St Helens, Washington were K-Ar tested to a date of 350,000 years old! answersingenesis . o r g / tj / v10 / i3 / argon . a s p Mt Ngauruhoe erupted several times in the past 25-50 years and several of these samples have been K-Ar dated to ages of 250,000 -- 3,500,000 years old! This is an 1,000,000% error! answersingenesis . o r g / creation / v22 / i1 / dating . a s p Diamonds are the hardest substance known and can not be penetrated with contaminants. Evolutionists teach diamonds formed millions or billions of years ago out of carbon deep in the crust. If this is true than the radioactive 14C should be undetectable after 100,000 due to its fast decay rate. Diamonds were sampled from 12 locations all over the world and they contained measurable amounts of 14C. icr . o r g / carbon-14 / CreationismCoal supposedly formed millions or hundreds of millions of years ago according to evolutionists but coal samples have also been tested and they also contain measurable amounts of 14C. These results support what the Bible says about the young age of the Earth and the world wide flood. icr . o r g / rate / Radiometric dating methods use a material of pressumed age as a control for calibration, such as a rock of assumed age or an index fossil (of assumed age). There is nothing imperical about dating methods. To this are added "fudge factors". Dating methonds are circular logic and incapable of dating anything because they do not use a material of empirically known age for calinration, and are therefore incapable of providng a date for anything. The sun produces C-14 in the upper atmosphere, and at the same time it decays which removes it from the Earth. Because the Earth has not acheived C-14 equalibrium but is instead still increasing, which would take approximately 30,000 yrs, C-14 verifies the fact that the Earth is less than 30,000 yrs old.
