Is there any possibility to obtain gold as a product of nuclear reaction of any radioactive element?
Fission products of uranium and plutonium are
1) Germanium-72, 73, 74, 76
3) Selenium-77, 78, 79, 80, 82
5) Krypton-83, 84, 85, 86
6) Rubidium-85, 87
7) Strontium-88, 89, 90
9) Zirconium-90 to 96
11) Molybdenum-95, 97, 98, 100
13) Ruthenium-101 to 106
15) Palladium-105 to 110
17) Cadmium-111 to 116
19) Tin-117 to 126
20) Antimony-121, 123
21) Tellurium-125, 127 to 132
22 Iodine-127, 129, 131
23 Xenon-131 to 136
24 Caesium-133, 134, 135, 137
25 Barium-138, 139
Nuclear fusion can create gold. However, gold is usually produced by fusion in high mass stars that die in supernovae, scattering the heavy elements they have created throughout the universe. The amount of power required to simulate this type of nuclear fusion is astronomical, meaning it is unlikely that earth nuclear reactors will be able to produce enough power to create more than minute amounts of gold. Fission could also create gold from radioactive elements, but again, the amount of gold would be minute.
thanks a lot, i learned new thing. But i don't believe its not possible in fission.
Oh it is entriely possible with fission. It's just that there's only only stable isotope of gold, so you'd have to produce only that isotope in order to get real results.
Since there is only one stable gold isotope, 197Au, nuclear reactions must create this isotope in order to produce usable gold.
Gold synthesis in a particle accelerator is possible in many ways. The Spallation Neutron Source has a liquid mercury target that will be transmuted into gold, platinum, and iridium, which are lower in atomic number.
Gold was first synthesized from mercury by neutron bombardment in 1941, but the isotopes of gold produced were all radioactive.
Gold can currently be manufactured in a nuclear reactor by irradiation either of platinum or mercury.
Only the mercury isotope 196Hg, which occurs with a frequency of 0.15% in natural mercury, can be converted to gold by neutron capture, and following electron capture-decay into 197Au with slow neutrons. Other mercury isotopes are converted when irradiated with slow neutrons into one another or formed mercury isotopes, which beta decay into thallium.
Using fast neutrons, the mercury isotope 198Hg, which composes 9.97% of natural mercury, can be converted by splitting off a neutron and becoming 197Hg, which then disintegrates to stable gold. This reaction, however, possesses a smaller activation cross-section and is feasible only with un-moderated reactors.
It is also possible to eject several neutrons with very high energy into the other mercury isotopes in order to form 197Hg. However such high-energy neutrons can be produced only by particle accelerators

I'm struggling to keep up with all this. Is Trump really planning to attack North Korea if they do another nuclear test? Is it seriously being considered as a possibility? Or is it just sabre rattling? And is this type of brinksmanship the best approach to foreign policy?

It is all falling neatly into place for the US to attack Iran on behalf of Saudi Arabia. The US views the plot as state-sponsored terrorism. Secretary of state Hillary Clinton described it as a "violation of international norms" and said she would discuss with allies in Europe and...

Can you explain to me what is an "isotope?"
