Half life of isotopes
WebJan 27, 2024 · Half-life is defined as the time it takes for one-half of a radioactive element to decay into a daughter isotope. As radioactive isotopes of elements decay, they lose their radioactivity and become a brand new element known as a daughter isotope. By measuring the ratio of the amount of the original radioactive element to the daughter isotope ... WebSo 14.3 days is the half-life of phosphorus-32. And this is the symbol for half-life. So, 14.3 days is the half-life for phosphorus-32. The half-life depends on what you're talking about. So if you're talking about something like uranium-238, the half-life is different, it's approximately 4.47 times 10 to the ninth, in years.

WebIsotopes of uranium. Uranium ( 92 U) is a naturally occurring radioactive element that has no stable isotope. It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in appreciable quantity in the Earth's crust. The decay product uranium-234 is also found. WebHalf-life is the length of time it takes for half of the radioactive atoms of a specific radionuclide to decay. A good rule of thumb is that, after seven half-lives, you will have less than one percent of the original amount of …
WebIsotopes of yttrium. Natural yttrium ( 39 Y) is composed of a single isotope yttrium-89. The most stable radioisotopes are 88 Y, which has a half-life of 106.6 days and 91 Y with a half-life of 58.51 days. All the other isotopes have half-lives of less than a day, except 87 Y, which has a half-life of 79.8 hours, and 90 Y, with 64 hours.
