7 The rate at which radioactive material decays is measured by its half life.The half life is the time it takes for one half of the atoms of a radioactive material to disintegrate.Marie models the radioactive decay of 1 gram of carbon-14.She us estheequationy=0.886^t .y is the propo...
Discover radioactive decay and the half-life equation. Learn how to use a half-life graph to write the equation for an atom's half-life and vice-versa. Related to this Question If the half life of carbon-14 is 5730 years, and a sample that has lost 80...

From the equation below, we can see that the longer the half-life of an isotope, the longer the mean lifetime will be. τ =t½/ln(2) How to Calculate Time Elapsed Using Radioactive Decay Using a technique known ascarbon dating, it’s possible to estimate the age of an organic comp...
{eq}20\% {/eq} of the carbon-14 in a wooden bowl remains. How old is the bowl (rounded to the nearest hundred years, and use {eq}5700 {/eq} years as carbon-14's half life)? Age of Wooden Bowl: To determ...
The half-life of carbon-14 is 5730 years. This means that after 5730 years have elapsed, half of an initial quantity of carbon-14 would have disintegrated. What is the half life of uranium? The half-life of uranium-238 is 4.5 billion years. It is one of the three natural occurring ur...
stable. By knowing the decay rate of carbon-14 (it has a half-life of 5,730 years), and measuring how much of the carbon-14 in the sample has transmuted into other elements relative to the amount of carbon-12, then it is possible to determine the ages of fossils and similar objects...
N0 = the initial quantity of the substance that will decayt1/2 = the half-life of the decaying quantity Half Life Statistics Visualized: Radioactive Decay: The half-life of Carbon-14, used in archaeological dating, is about 5,730 years. Source from National Geographic Medicine: The half-...
The half-life of carbon-14 is 5,730 y. Carbon-11 is a radioactive isotope used in positron emission tomography (PET) scans for medical diagnosis. Positron emission is another, though rare, type of radioactivity. The half-life of carbon-11 is 20.3 min. If 4.23 × 10−6 g of carbon...
