Radioactive Decay: Half-lifeRyan Bruels
Half-Life Continued Decay Product- Daughter product, the element produced by the decay of a radioactive isotope. By studying the amount of decay product left over from the radioactive elements in a rock, we can determine the absolute age. Example- If a fossil with C14 is found containing 50...
Carbon-10 has a half-life of about 19 seconds. How many half-lives does it undergo in 2 minutes and 13 seconds? Half-Life: A half-life refers to the amount of time it takes for half of the atoms of a radioactive sample to decay. For ex...

The term half-life is appropriate due to the exponential and quantum nature of radioactive decay, which makes it impossible to predict exactly when a single atom of radioactive material will disintegrate. The half-life measurement instead relates to stat
The half-life (T½) of a radioactive substance is the time required for a population of atoms to decay to half the original number. From:Leibel and Phillips Textbook of Radiation Oncology (Third Edition),2010 Chapters and Articles
whereNis the number of radioactive nuclei present, having half-lifet1/2. This relationship is useful in a variety of calculations, as the Examples 2 and 3 illustrate. Example 2. How Great Is the14C14CActivity in Living Tissue? Calculate the activity due to14C in 1.00 kg of carbon found ...
Half-Life formula You can find the half-life of a radioactive element using the formula: wheret1/2is the half-life of the particle,tis the elapsed time,N0is the quantity in the beginning, andNtis the quantity at timet. This equation is used in the calculator when solving for half-life...
You are surrounded by radioactive isotopes. However, many don't pose much of a threat because they have such long half-lives. The half-life of a radioactive isotope is the time it takes for half of the sample to react, or decay. This time can range anywhere from a portion of a seco...
