How long would it take for plutonium to decay to one eighth of its original activity?
For plutonium (or any other radionuclide) to decay to one eighth of its original activity, it will take 3 half-lives of the material. In one half-life, half is gone. Half will be left. In another half-life, half of the half that was left is gone, and one quarter will be left. In a third half-life, half the one quarter will be left, and that's one eighth of the original. In the case of plutonium, there are a number of isotopes of this highly radioactive stuff. The isotope 239Pu, which is commonly used in nuclear weapons, has a half-life of 2.41 x 104 years. That's 24,100 years. For 239Pu to decay to 1/8 th of its original amount, it will take 3 time the half-life, which is 7.23 x 104 years, or 72,300 years. And yes, that is a long time. A very long time....

What particles does plutonium give off?
Plutonium is especially an alpha particles emitter.
What is given off by radioactive elements such as radium and Plutonium?
From these isotopes decay products are obtained and also ionizing radiations.
What produces plutonium?
When chain reacting uranium, other elements are formed, some are heavier and others are lighter. As these elements decay due to radioactivity, some certain chemicals change into plut. But only a very small amount is made.
How is plutonium used in spacecrafts?
Plutonium is used in spacecrafts to power radioisotope thermoelectric generators (RTGs). These generators use the heat produced by the decay of plutonium-238 to generate electricity, providing a reliable power source for spacecraft on missions where solar power is not feasible, such as outer planets or deep space missions.
What is the energy source for the voyager 1?
Voyager 1 uses radioisotope thermolectric batteries, powered by the heat generated from the decay of a radioactive substance. In this case, plutonium oxide.
Is plutonium cold or warm?
Plutonium is warm; the cause is the heat released by radioactive decay.
What is the product of alpha decay?
plutonium-239
To what does plutonium-239 decay when it loses an alpha particle?
Yes, plutonium-239 emits alpha particles by decay.
What kind of decay must neptunium-239 undergo in order to generate plutonium-239?
Neptunium-239 must undergo beta decay to generate plutonium-239.
How long will it take 24 grams of plutonium -240 to Decay to 20 gram?
The half-life of plutonium-240 is about 6,560 years. If 24 grams decay to 20 grams, it represents a loss of 4 grams of plutonium. The time it would take for 24 grams to decay to 20 grams would depend on the specific decay rate and is typically calculated using exponential decay equations.
If you had a 100 gram sample of plutonium how much would remain in 43 years?
Plutonium-239 has a half-life of about 24,100 years, meaning it takes that long for half of a sample to decay. In 43 years, which is much shorter than the half-life, only a tiny fraction of the plutonium would decay. Therefore, after 43 years, approximately 99.83 grams of the original 100-gram sample would remain.
Is plutonium the result of of the alpha decay of uranium?
Yes, plutonium is typically formed as a result of the alpha decay of uranium in nuclear reactors or in nuclear weapons. It can also be produced artificially in nuclear reactors by bombarding uranium-238 with neutrons.
After 7 minutes a 53 g sample of plutonium decays to 36 g how long will it take for the sample to decay to 13 of its original amount?
It will take 25.0898 minutes, approx.
What particles does plutonium give off?
Plutonium is especially an alpha particles emitter.
Which equation represents the alpha decay of plutonium 244?
The equation for the alpha decay of plutonium-244 is: [ ^{244}{94}Pu \rightarrow ^{240}{92}U + ^4_2He ]
How long does it take for 1kg of plutonium to decay to 1g?
The half life is different for each isotope of plutonium; name the isotope for a calculation.
What is the decay products of americium 241?
The decay products of americium-241 include neptunium-237, plutonium-241, and various isotopes of neptunium, plutonium, and uranium. These decay products are formed as americium-241 undergoes alpha decay and transforms into new elements through a series of radioactive decays.
