Would radioactive waste still remain dangerous after millions of years?

No. Short-lived isotopes will disappear by then; some long-lived isotopes may survive, but they will have a low level of radiation.

Why not dispose of nuclear waste in a volcano?
Mecause melting does not destroy the radioactivity. Whatever burns would cause radioactive ash/smoke that would be carried away on the wind. the rest would just turn a patch of the lava radioactive.
What happens if radioactive waste is dumped in the sea?
YEs The radioactive materials would probaly kill the sea creatures
Why would a fusion reactor produce less radioactive waste than a fission reactor?
In my understanding, this is because a fusion reactor reacts deuterium to produce helium, which is not radioactive, whereas a fission uses uranium or plutonium, for example, which may react to form various radioactive isotopes. A fusion reactor may contain small quantities of tritium, in which case a radioactive isotope of hydrogen may be produced, but given that the majority of reactions occurring involve solely the deuterium, there is less radioactive waste produced.
How much would it cost to kiss Justin Bieber?
Millions im not even sure if he would let you !!!!!
Can all radioactive isotopes be used in radiometric dating?
No, not all radioactive isotopes be used in radiometric dating. Some have very very short half lives and would entirely disappear before any useful period of time passed.
Can citizens own Uranium?
No, it would be very dangerous as it is radioactive.
Radioactive decay speeds up at higher temperatures?
No, radioactive decay is not affected by temperature, at least, not in anything like a normal range. At millions of degrees, yes, it would speed up.
How much cesium would remain from a 10g sample after 4 years?
I suppose that you think to the radioactive isotope Cs-17; After 4 years remain 9,122 g.
If a radioactive material has a half-life of 10 years what fraction of the material will remain after 30 years?
One eighth would be left.
Why would it be dangerous to handle even small amount of radium?
Radium is strongly radioactive and emit alpha, beta and gamma radiations. These radiations are very dangerous for all the beings.
Can the mass affect the density of metals?
Yes. And if massive enough then the density may increase due to gravitational attraction in a matter of time we can perceive. even with a small mass this is happening, however it may take 1000s to millions of years for it to be measurable.In most cases the mass would remain the same (absent radioactivity losses) but the density would increase. If highly radioactive its mass would likely decrease over time.
How long would the area near a nuclear power plant remain radioactive after an accident?
Basically a very long time. Most radioactive isotopes are radioactive for a long time. Uranium 232 has a half life of 69 years and plutonium 238 has a half life of 88 years. Some isotopes are very long lived.
If a certain radioactive substance has a half life of one year how many atoms of the substance remain after 5 years if there are initially 5000 such atoms?
Half life refers to the time required for the change (decay) of a radioactive nucleus to a lighter, possibly more stable, nucleus.Starting with 5,000 radioactive atoms, at the end of first year, half would have decayed leaving 2,500. Following the same pattern, the end of the second year would see only 1,250. By the end of year 5, there would be just 156 radioactive atoms.
What is the purpose for nuclear waste?
Nuclear waste is an unfortunate by-product of the process of nuclear fission for the purpose of energy production. The spent fuel rods are "safely" stored and sequestered, but will remain dangerous for thousands of years. As far as I know, there is no "purpose" for nuclear waste, other than to convince people that they do not want a power plant in their backyard. The theoretically possible process of nuclear fusion (which is how the sun works) would produce less radioactive material and waste.
What is the decay element of uranium?
It is not yet discovered since all of the uranium isotopes are having half life for several millions of years. We would be able to find it after atleast 700 millions of years.
Why dont radioactive elements have a stable nucleus?
By definition. If it were stable, then it would not be radioactive.
