The half-life of bismuth-209 is approximately 1.9 x 1019 years.
The half-life of uranium-239 is 23.45 minutes.
If the substance has a half-life of 10 years, there would be 10 half-lives in a 100-year span. Each half-life reduces the amount by half, so after 100 years, 1/2^10 = 1/1024 grams of the sample would remain.
No. However one of the fission products produced is Iodine-131 and it appears in the fallout. Iodine-131 is a dangerous beta and gamma emitter with a halflife of 8.05 days, it concentrates in the thyroid gland and can selectively kill it or cause cancers in it. Fortunately the halflife is only just over a week, because it then practically disappears in about 5 to 6 weeks. This allows Iodine-131 contaminated food and drink (e.g. fresh milk) to be stored and then safely used when the Iodine-131 has decayed. This also makes it possible to protect the thyroid gland by saturating it with ordinary Iodine (usually as potassium iodide pills) until the Iodine-131 has decayed.
this is an example of β radiation, n -> p + e Rb-87 -> Sr-87 + e (rem to write atomic numbers in, Rb is 37 and Sr is 38) The halflife 87Rb is 4,88.1010 years.
Uranium-235Uranium-233Plutonium-239DeuteriumTritiumAs tritium is radioactive with a short halflife (12 years), weapons using it age rapidly possibly becoming unreliable. Therefore it is normally produced from Lithium (in the form of Lithium Deuteride) by fission neutron bombardment just before fusion is initiated.
Illadelph Halflife was created on 1996-09-24.
Yes.
The logo has a border, however the lambda is in the center.
Yes, but it has a halflife of only 0.86 seconds.
Go out and buy it. You can't download it.
The half life of plutonium-235 is 25,3(5) minutes.
yes it has the full games halflife 2, portal, and TF2
3-5 days, 18-50 hour halflife

On an object with unknown age but more than halflife of C
For the half lives of all curium isotopes see the link below.
many. one example is lead-214 with a halflife of 26.8 minutes.
