In a reactor, or atomic bomb, uranium 235 (for example) will not always split into the same kinds of atoms; rather, different kinds of waste products can be produced. Some of them will decay faster, some slower. The real problem is with products that have a half-life of a few decades or centuries. If a product (like uranium itself) has a half-life of billions of years, the radiation it gives off will not be very significant. If on the other hand a product has a half-life of days - well, the radiation will be very strong, but after a few weeks not much is left. However, part of the nuclear waste can remain for decades or centuries, and still give off a significant amount of radiation. No specific timeframe can be given - if (say) a certain isotope has a half-life of 50 years, that means that after 50 years, half of the substance will be left; after another 50 years, a quarter of the original substance, etc. It will not suddenly disappear at a certain moment; but after several times the half-life, the amount left will be insignificant. On the other hand, the by-products of this decay can again be other radioactive isotopes.
What else can I help you with?
Is the parent element always radioactive in a nuclear reaction?
No, the parent element in a nuclear reaction is not always radioactive. While many parent isotopes are indeed radioactive and decay into stable or unstable daughter isotopes, there are also stable isotopes that can undergo nuclear reactions without being radioactive themselves. For example, stable isotopes can be involved in nuclear reactions such as neutron capture or fusion, but they do not decay over time like radioactive isotopes.
What is a radioactive decay of the spent fuel?
Radioactive decay of spent fuel refers to the process where the radioactive isotopes in the fuel break down and release radiation and particles. This decay can continue for thousands of years, making spent fuel a long-term radiation hazard. Proper storage and disposal methods are necessary to prevent environmental and health risks.
The half-life of isotope X is 2.0 years how many years would it take for a 4.0 mg sample of X to decay and have only 0.50 mg of it remain?
It would take 4 half-lives for a 4.0 mg sample of X to decay to 0.50 mg. Since the half-life is 2.0 years, it would take 8.0 years for this decay to occur.
How many years is the useful life of a nuclear fission reactor?
The useful life of a nuclear fission reactor is typically around 40-60 years. However, this can vary depending on factors such as maintenance, upgrades, and regulatory approvals.
How many years will it take for 10 g of radioactive uranium to decay into 5 g of radioactive uranium?
It would take one half-life for the 10 g of uranium to decay into 5 g. The half-life of uranium is around 4.5 billion years, so it would take approximately 4.5 billion years.
Will nuclear waste be dangerous to future generations?
Absolutely ! Nuclear waste takes hundreds - perhaps thousands of years to decay. Many generations of people to come will have to manage the storage and disposal of nuclear waste.
Why does nuclear energy last 500 years?
Nuclear energy lasts for 500 years because of the half-life of the radioactive material used in nuclear reactions. This means that it takes 500 years for half of the radioactive material to decay into a stable form. After many half-lives, the material becomes non-radioactive and safe for disposal.
How many decay does 100 years?
If you mean decades then there are 10 decades in 100 years
How many years has nuclear fission been used?
About seventy years.
Where do nuclear decay occur naturally?
Radioactive Decay occurs naturally all around us. If you test for radiation with a Geiger Counter, you will find that it picks up radiation in the air around you. Mostly, however, radioactive decay occurs in the earth's crust. I cannot name a specific element, as there are many that decay.
How many radioactive isotopes are there in Zirconium?
Zr 94: half life 1,1.1017 years, double beta decay Zr 96: half life 2,0.1019 years, double beta decay
How many years to complete nuclear medicine degree?
20 kwadrillion

How many years of experience do you need to become a nuclear reactor system engineer?
my cousin became a nuclear reactor engineer and he said it was about 12 years
Particles or waves given off by atoms undergoing nuclear decay produce?
Produce a large amount of heat and energy which is utilized for many purposes
How many years passed from the first controlled nuclear reaction to the first nuclear meltdown?
The first controlled nuclear reaction took place in 1942 at the University of Chicago. The first nuclear meltdown occurred at the Chernobyl Nuclear Power Plant in 1986, which is 44 years later.
What is the random nature of nuclear decay and how does it relate to half life?
There is a simple connection between the random nature of nuclear decay and the half-life of a radionuclide. Any given atom of a radioactive element can undergo decay "any time it wants to" in the real world. This is the random nature of radioactive decay. We absolutely cannot tell whenthat one atom of whatever it is will decide to decay. The nuclear decay will happen when "it wants to" and we can only speak to the decay event of a given radionuclide by statistical means.We look at a vast number of the same kind of atoms and count the decay events. We do this over some determined interval of time, which can be shorter or longer, depending on how unstable the given radioisotope is. We'll then use our knowledge of how much we had to begin with and how many decay events we observed over out observation period to calculate how long it takes "about half" the material to decay. That's what a half-life is. It's a statistically derived span of time during which half the amount of a (sufficiently sized) sample of a specific radionuclide will decay and half will be left to undergo decay later on.
