Because the fragments' binding energies per nucleon (the energy required to overcome electrostatic repulsion) is too low for stability. Subsequent decays eventually form stable lead

What are fission fragments?
When an atomic nucleus fissions, it splits into smaller atomic nuclei. These smaller atomic nuclei are referred to as "fission fragments." The unstable nucleus of a radioactive element can fission (split) into smaller nuclei, i.e. those of lighter elements. This can also release other atomic particles, as well as energy. In nuclear power and atomic weapons, the fission process is initiated to release the nuclear energy. Natural fission is a much rarer occurrence than radioactive decay.
What is fission product?
Fission products are the fragments resulting from the fission of heavy nuclids during nuclear fission process
None of the products of nuclear fission of uranium are radioactive?
The answer is FALSE. Products of Nuclear fission of Uranium are highly radioactive.
What is a radioactive decay of the spent fuel?
The nuclear fission process produces a range of lighter elements as fission products, and many of these are radioactive.
Between nuclear fission and fussion radioactive by-product are more characteristic of which?
Fission

The atoms that remain after a nucleus disintegrates is?
smaller then the original atom and possibly radioative
What is fission product?
Fission products are the fragments resulting from the fission of heavy nuclids during nuclear fission process
What does uranium emits while it breaks down?
Fission fragments, neutrons, gamma radiations; and all the radiations emitted by these fission fragments.
Why does nuclear energy have radioactive stuff in it?
It is simply a fact that nuclear fission produces radioactive fission products
How many Radioactive elements fallout from a hydrogen bomb?
Probably around 50 to 60 as most of the fallout is fission fragments from fissions of the uranium-238 radiation casing surrounding the fusion stage due to 15MeV fission neutrons generated. About 90% of the bomb yield is from this fission also.
None of the products of nuclear fission of uranium are radioactive?
The answer is FALSE. Products of Nuclear fission of Uranium are highly radioactive.
Are the products of nuclear fussion radioactive?
no, but the products of fission are radioactive
Why is it called Nuclear Fission?
It is called nuclear fission as in this process the heavy nuclei are split into fragments (or fission products).
Are some nuclear wastes stored for centuries to prevent dangerous radioactivity from escaping?
Yes. Some radioactive waste, like spent nuclear fuel, remains highly radioactive for thousands of years. Attempts were made to reprocess the spent fuel, but it is extremely dangerous and it is not very cost effective in many cases to do so. There are other forms of radioactive waste generated every day, but we work at being careful about what we generate to avoid having to store it. But the problem with nuclear fuel is a major one. Spent fuel is far and away the major contributor to high level radioactive waste in the world. Consider that 235U and 239Pu are the most common nuclear fuels. When they fission, they leave behind fission products. (The atom of fissile material "split in two" and there are a pair of fission fragments. Different pairs of fragments are possible.) With either fuel, there are over a dozen fission products from the fission process that have a half-life measured in thousands of years. There are a lot of fission products in the spent fuel, they are highly radioactive, and the remain highly radioactive for thousands of years after use. We can't just throw them away.
