Why is plutonium radioactive?
No it does not. There are various types (isotopes) of plutonium. Plutonium 238, the weapons grade material, has a half life of 88 years. Meaning after 88 years half of the material has transforms into another element through radioactive decay. Plutonium-240 has a half life of ~80 Million years. But eventually all types of plutonium will decay into other elements. All radioactive elements will eventually decay into non-radioactive atoms given enough time.
Does plutonium have a half-life of 25000 years?
The isotope Pu-239 does. (It's actually about 24,100 years). Other isotopes of plutonium have a different half-life, and these vary (for the more common isotopes) from a few years to millions of years. A link can be found below.
What is more radioactive uranium or plutonium?
There are numerous isotopes of both plutonium and uranium ( all radioactive) thus it is not easy to say which element is more radioactive. However the half lives of the most active isotpe of each compound is follows241Pu has a half life of 14 years232U has a half life of 68.9 yearsSo in terms of activity, Plutonium is more radioactive; however uranium stays radioactive for a longer time.The specific activity of plutonium is greater than the specific activity of uranium (comparison between 239Pu and 238U).
How long does it take plutonium to decompose?
depends on the type of waste, that determines its halflife. some waste will be safe in just a few decades, other types will take millions of years. if they would reprocess reactor nuclear waste so that uranium, plutonium, and other transuranics were recycled as fuel instead of staying in the waste; the remaining waste could be stored in a repository for 100 to 200 years and be safe after that.
If you had a 100 gram sample of plutonium how much would be left in 43 years?
The half life of the isotope 239Pu (the most known plutonium isotope) is 24,200 years; 43 years is practically nothing in comparison is 24,200 years so you would still have 100 grams.
What is half life of plutonium?
The half life of plutonium-239 is 2,41.10e+4 years.
What is the halflife of plutonium 235?
The half life of plutonium-235 is 25,3(5) minutes.
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 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.
How long does the radiation from plutonium 131 last?
Not plutonium, but iodine-131 !!The half life of 131I is 8,0197 days.
What is the half life of plutonium 241?
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.
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.
Plutonium-32 has a half-life of 14.2 days How many half-lives have passed in 99.4 days?
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.
Does plutonium have atleast one non radioactive isotope?
No, it does not. The longest lived isotope, plutonium-244, has a half life of 80,800,000 years.
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.
How many half lifes with in plutonium?
The half life of the isotope Pu-239 is 2,41.10e+4 years.
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.
