What is the half-life of uranium 239?
Pu-239 has a half-life of 24,110 years.
What is difference between plutonium 238 and 240?
Plutonium-238 has 144 neutrons, plutonium-240 has 146 neutrons. Atomic mass and half life are also different.
What is an isotope that the time it takes it to decay to half its original mass?
c.half-life
What is the half life of promethium?
Promethium 145 has a half life of 17.7 years. Promethium 146 has a half life of 5.53 years. Promethium 147 has a half life of o.22 years.
What particle is emitted when Pu-240 decays to U-236?
240Pu decays to 236U by emitting an alpha particle. You can tell this by looking at the difference in atomic mass. 240 minus 236 is 4, and that is the mass of an alpha particle. You can also tell this by looking at a chart of the nuclides. See the related link below for an example from Brookhaven National Laboratories.
What does Pu-239 has a half-life of?
Pu-239 has a half-life of 24,110 years.
What is the half-life of uranium 239?
Pu-239 has a half-life of 24,110 years.
How many half lifes with in plutonium?
The half life of the isotope Pu-239 is 2,41.10e+4 years.
How long has plutonium got left?
If you think to the half life this value for the isotope Pu-29 is 2,41.10e+4 years. Each isotope has another half life.
How long is plutonium active in radiation?
Plutonium remains radioactive for a long time as the half life is 87.7 years for Pu-239. The half life is how long it takes for half of the radioactivity to dissipate.
What is half of 240?
Half of 240 is 120.120120
What is the half-life of plutonium-239?
Plutonium has 20 isotopes; each isotope has another half-life. Please read: http://en.wikipedia.org/wiki/Isotopes_of_plutonium.
What is the stability in plutonium?
Being a radioactive chemical element plutonium is not stable.The half life of the isotope Pu-239 is 2,41.10e+4 years.
Plutonium-241 is an isotope of plutonium that is highly radioactive and is used in some nuclear reactors and many nuclear weapons It has a half-life of 14.4 years If 1000g of Pu-241 is placed in sto?
Question incomplete. Pu-241 is formed from Pu-240, the longer the fuel is irradiated in the reactor the more of the higher mass Pu isotopes are formed. This is why to produce weapons grade Pu, which must be mostly Pu-239, the fuel has to be irradiated only for a limited period. Pu-241 is fissile, so could be used in a weapon, but I believe the disadvantage is that it fissions spontaneously which can lower the weapons efficiency. I suggest you (a) complete the question, and (b) put it in the Nuclear Weapons category, possibly also Nuclear Physics, rather than Nuclear Energy which I take to be about civil use of nuclear power.
What is difference between plutonium 238 and 240?
Plutonium-238 has 144 neutrons, plutonium-240 has 146 neutrons. Atomic mass and half life are also different.
What is half of 4.80?
half of 480 is 240
What is 17and a half percent of 240?
.175 x 240 = 42
