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.
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.
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.
The half life of the most important isotope (239Pu) is 2,41.104 years.
To find the time it takes for 36 grams of plutonium-240 to decay to 12 grams, we can set up the equation 12 = 36 * e^(-0.00011t) and solve for t. The result is t ≈ 180 years. Therefore, it will take approximately 180 years for 36 grams of plutonium-240 to decay to 12 grams.
The decay of plutonium-240 has a half-life of about 656 million years. To go from 36 grams to 12 grams would require two half-lives, so it would take approximately 1.3 billion years for 36 grams of plutonium-240 to decay to 12 grams.
The half life of plutonium-235 is 25,3(5) minutes.
The halflife of Plutonium-239 is 24,400 years. However this is long enough to allow plenty of time to changeout those parts before they affected the bomb. Other parts (e.g. explosives, neutron sources) will age faster.
- intermediate in the preparation of plutonium 238 - in the instruments for the detection of high energy neutrons - possible use in the future as material for nuclear weapons - possible use in the future as nuclear fuel
The half life of plutonium-239 is 2,41.10e+4 years.

Carbon monoxide is a poisonous gas that can be lethal when inhaled. It can cause symptoms like dizziness, confusion, and even death if concentrations are high enough. It is important to have a carbon monoxide detector in place to reduce the risk of poisoning.
Approx 2.85 years.
Between 68 and 69 years.
The half-life of plutonium-241 is about 14 years. This means that it takes approximately 14 years for half of a sample of plutonium-241 to decay into another element.
