Your sample of phosphorous will literally half itself every 14 days. So after 14 days there is 12mg left. After 28 days, there is 6mg remaining.
The half-life of uranium-239 is 23.45 minutes.

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.
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.
Yes, but they also consume them. The uranium fuel used has a halflife measured in billions of years, the materials they produce have halflives measured in only hundreds or thousands of years. So in the long term balance of things they consume radioactive substances faster than they produce them.
Illadelph Halflife was created on 1996-09-24.
Yes.
The radioactive decay of Phosphorus-32 emits only betaparticles (i.e. electrons) with a halflife of slightly longer than two weeks. No electromagnetic radiation at all is emitted.
yes
U-238 --> alpha + gamma + Th-234, halflife 4.51E9 yearsTh-234 --> beta- + gamma + Pa-234, halflife 24.10 daysPa-234 --> beta- + gamma + U-234, halflife 6.66 hours
Yes, but it has a halflife of only 0.86 seconds.
The logo has a border, however the lambda is in the center.
The half-life of uranium-239 is 23.45 minutes.
Go out and buy it. You can't download it.
The half-life of carbon-11 is 20.334 minutes.
The half life of plutonium-235 is 25,3(5) minutes.
3-5 days, 18-50 hour halflife
