What is radioactive half-life used for?
to determine how long it will take to half of nuclids to decay, having use in radioactive materials operations
Does half life of any radioactive element decrease when its used?
The half-life can not be changed by any normal means.
The rate of decay of a radioactive element is measured by its what?
Any of the following can be used: the half-life, or the mean lifetime, or the decay constant.Any of the following can be used: the half-life, or the mean lifetime, or the decay constant.Any of the following can be used: the half-life, or the mean lifetime, or the decay constant.Any of the following can be used: the half-life, or the mean lifetime, or the decay constant.
Why is half life a radioisotope important for radioactive dating?
the half life forms a type of clock used to calculate time passed
Is francium used in radioactive lasers?
Francium has an extremely short half life of about 20 minutes so no it is not. Radioactive lasers do not use radioactive materials anyway.
How is half time used on an element?
If you mean HALF LIFE, that is the length of time it takes a quantity of a radioactive element to lose half its radioactivity.
What is meant by th term effective half life of a radioactive isotope used in medicine?
when it ends.
What property of radioactive isotopes allow them to be used to determine the age of rocks and fossils?
Their half life.
How are radioactive isotopes used to determine the absolute age of igneous rock.?
Answer : When the isotopes decay, scientists can find out how old the rock is depending on the radioactive isotope's half-life. Explanation: Radioactive isotopes are unstable and will decay. For example, when humans die carbon-14 decays. The isotopes will decay into a stable isotope over time. Scientists can tell how old the rock was from looking at the radioactive isotope's half-life, which tells them how long it would take for there to be half the radioactive isotope and half the stable isotope. At the next half-life there will be 25% of the radioactive isotope and 75% of the stable isotope. At the next half life there will be 12.5% radioactive and 87.5% stable. Example: Carbon-14 is a radioactive isotope with a half life of 5,730 years. How old would carbon-14 be when there is 75% carbon-14 in the rock? 75% is half of the time before the half-life, so it would be 2,365 years. Hope this helps. Half life helps scientists find how much the isotope has decayed and the age of the rock.

How do you find the half life in carbon dating?
You do not find the half life in carbon dating. The half lives of carbon isotopes are derived by studying their radioactive decay. For carbon dating, the isotope used is Carbon-14, which has a half life of 5,700 years.
What is the half life of C14?
The half life of Carbon 14 used for radioactive decay id 5,700 years
