Plutonium 241 has a half life of 14 years. Storing the nuclear waste of plutonium can be very hazardous and needs to be stored for hundreds of thousands of years before it is totally safe.
Plutonium has 20 isotopes; each isotope has another half-life. Please read: http://en.wikipedia.org/wiki/Isotopes_of_plutonium.
no it is man made in china and other ciuntries such as japan england and packastan
Some plutonium chemical compounds; plutonium dioxide, plutonium nitride, plutonium carbide, plutonium nitrate, plutonium trifluoride, plutonium chloride, etc.
* Approx. 115 US $/kg of the unrefined oxide U3O8 (but not for the nuclear grade, which is more expensive) - in July 2011. * The price of plutonium is probably 4 000 US $/g; the price depends on the isotopic composition and purity (nuclear fuel grade, weapons grade).
The isotope symbol of plutonium with 146 neutrons is plutonium-246, represented as ^246Pu.
Plutonium-241 is an isotope of plutonium with a half-life of about 14 years. It is used primarily in batteries for spacecraft and military applications due to its heat-producing decay process. It is also a source of neutrons for various scientific research purposes.
The half life of plutonium-239 is 2,41.10e+4 years.
The half life of americium-241 is 432,2(7) years.
The half life of americium 241 is 432,2 years.
Plutonium has 20 isotopes; each isotope has another half-life. Please read: http://en.wikipedia.org/wiki/Isotopes_of_plutonium.
The half life of the most important isotope (239Pu) is 2,41.104 years.
The half life of plutonium-235 is 25,3(5) minutes.
Plutonium-239, a common isotope of plutonium, has a half-life of about 24,100 years. To calculate the number of half-lives, divide the total time by the half-life. For example, in 48,200 years, there would be 2 half-lives.
Not plutonium, but iodine-131 !!The half life of 131I is 8,0197 days.
P-239 and P-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.
A half-life is simply the amount of time it takes for a substance to reduce itself by half. In this case, every 14.2 days half of plutonium-32 is converted into something else. All you have to do is divide 99.4 by 14.2, which is exactly 7. About 0.78% of the plutonium will be remaining at this time.
