WebModeling Radioactive Decay A mini lab worth 25 points Introduction: Half life is defined as the amount of time it takes for one half of a radioisotope to undergo decay. After one half life, one half will have decayed. After the second half life, half of that half will have decayed. This process continues until all of the radioisotope has undergone decay. . Think of the … WebThe half - life for radioactive decay of ^14C is 5730 years. An archaeological artifact containing wood had only 80% of the ^14C found in a living tree. Estimate the age of the sample.

WebHalf-life is a measure of the time it takes a radioactive sample to decrease its mass or quantity by half and, among other things, its danger. However, the half-life isn’t just about the danger of radioactive substances – we can also use it for many other applications, such as carbon-14 dating techniques.. What is nuclear decay?
