There are different ways of looking at this. And one should be warned that the idea of a half life is not immediately applicable to safety. Knowing the half life, you still have to do a lot of calculating, more than ordinary people can do in their heads.
The government of the United States has said high level waste from nuclear power plants will be safe in about 1,000,000 years. Unfortunately, there is no easily understood explanation of how they came to that number.
A much more easily understood number is used in Europe. The standard is that the material is safe when its radioactivity is no more than what comes from naturally occurring ores of uranium. This is easier because it can be calculated with some degree of precision, and the idea of safety is understandable. The number arrived at is 6,000,000 years.
To understand this fully, we have to keep in mind what 1,000,000 or 6,000,000 years means. Human history is only 5500 years old. But that history only applies to the places where it existed. Recorded history of most parts the world, including most of Africa, all of North and South America, and much of northern Europe and Asia is less than 1000 years old. It is really hard for anyone to imagine 1,000,000 years or what will happen in that time.
If you put nuclear waste in a situation where groundwater can flow over it on the way to a water course, you will obviously get contamination. Nuclear waste stores have to be very carefully considered to find locations that are safe from water access.
All countries that have nuclear reactors have nuclear waste and it is always a problem, though a manageable one.
It is the Yucca Mountain Nuclear Waste Repository.
its a method use in nuclear waste management where the waste is concentrated and then isolated. this method also use for non nuclear waste management.
No, you will get sick and die from leukemia, or other cancer by the radioactive waste lying around.
Nuclear fission produces nuclear waste which has to be desposed off and because of the nuclear waste's long half-life it takes thousands of years before the waste becomes safe. Mining for U-238 is expensive and an enrichment process is required to turn U-238 to U-235 before it can be used in a nuclear reactor, this takes time and money and is another disadvantage.
nuclear waste is worst

nuclear waste
Yes, there is nuclear waste in space.
nuclear waste is a by product of nuclear power plants, or in the creation of nuclear weapons.
nuclear waste contains about 90 % of nuclear fuel but it is much harmful then nuclear itself.
If you put nuclear waste in a situation where groundwater can flow over it on the way to a water course, you will obviously get contamination. Nuclear waste stores have to be very carefully considered to find locations that are safe from water access.
All the men you've seen naked have had great exposure to nuclear waste.
Because you can reuse 17% of nuclear waste and use it as if it was new.
The government and companies will pay states and cities money for using their land for storage of nuclear waste. Nuclear waste can be dangerous, but when stored safely it is no danger. Nuclear waste is produced by nuclear power plants, which produce large amounts of cheap electricity.
All countries that have nuclear reactors have nuclear waste and it is always a problem, though a manageable one.
