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.
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
Why need positron?
Positrons are used for 'PET', a medical imaging tomography technique. The positrons are produced in the radioactive decay of Sodium 22.
What system is used by scientists to measure matter?
mass is the quantity of matter in an object the kilogram (kg) is used to measure mass
When does radioactivite decay occur?
Radioactive decay happens in an unstable isotope of a given element, as the isotope decays radiation is given off. As for when exactly, the decay of a nucleus is spontaneous and random so averages are used, these averages are different for different isotopes, but are measured as the "half life" (the time it takes for half the nucleus to decay).
Use the term radioactive decay in a sentence?
"The radioactive decay of certain unstable isotopes is used to calculate the age of objects."
What types of elements are useful for dating materials?
Radioactive elements are used to date the age of rocks. Radioactive elements decay according to a known pattern. Scientists can use the elements of that pattern to determine when the rock with the original radioactive element was formed.
How is radioactive decay used to determine the absolute age a rocks?
The basic idea is to measure the amount of the radioactive isotope, and of one or more of its decay products. The older the rock, the larger the percentage of the original isotope that decayed - so the ratio between the original isotope and the decay product changes over time.
Why are radioactive materials used to date rocks rocks?
Radioactive materials decay at predictable rates
Importance of radioactive decay?
it is used by scientist to to calculate a rock's age

Can you get power from the radioactive element Uranium?
Yes, the radioactive decay of Uranium-235 is used to produce power in nuclear power plants.
Is radioactive decay used to find the absolute age of a rock?
its not from radioactivity its from carbon dating
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.

Why must radioactive decay must be constant in order for radioactive dating to be accurate?
Amount of certain radioactive isotope in an object is compared with a reference amount. this ratio can then be used amount.
