The half-life of cobalt-57 is about 271.74 days.
No, uranium-238 has a long half-life of about 4.5 billion years. It is a naturally occurring isotope that is commonly found in nature. Shorter-lived isotopes, such as radon-222 or polonium-214, have much shorter half-lives.
To determine the half-life of the substance, you can use the fact that after one half-life, the substance will be reduced to half of its original amount. In this case, after 40 days, the substance is reduced to one sixteenth of its original amount, which represents 4 half-lives (since 1/2^4 = 1/16). Thus, each half-life of this substance is 10 days.
If a sample of radioactive material has a half-life of one week the original sample will have 50 percent of the original left at the end of the second week. The third week would be 25 percent of the sample. The fourth week would be 12.5 percent of the original sample.
Most uranium is U-238, with has a very long halflife. Bombard it with neutrons (fast breeder reactor) to make plutonium-239, which is a suitable fuel for a fission reactor. Lift it up high, and tie a rope to it. As it falls, have it drive a generator. Same scenario, only drop it into a black hole... get lots more energy.
First, it isn't very accurate to talk about a radioactive "element"; you should talk about radioactive isotopes. Different isotopes of the same element can have very different behavior in this sense. For example, hydrogen-1 and hydrogen-2 are stable, while hydrogen-3 is not (half-life about 19 years).Individual atoms, in a radioactive isotope, will decay at a random moment. The half-life refers to how long it takes for half of the atoms in a given sample to decay (and convert to some other type of isotope).

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

many. one example is lead-214 with a halflife of 26.8 minutes.
