Gaseous products of a disintegrating radioactive substance such as thoron or radon?
The gaseous products of a disintegrating radioactive substance such as thoron or radon usually include isotopes of helium or polonium. These isotopes are formed as a result of radioactive decay and are emitted in the form of gas. They can pose a health risk if inhaled, as they are radioactive and can accumulate in the lungs.
How id helium gas artificially produced?
Helium gas is not artificially produced, as it is created by natural radioactive decay of certain elements, such as uranium and thorium, in the Earth's crust. However, helium can be extracted from natural gas through a process called cryogenic distillation. This involves cooling the natural gas to extremely low temperatures, which causes helium to separate from the other gases present.
How does uranium affect people?
Uranium is a pollutant, toxic and radioactive. Human exposure (and also the exposure of all living beings) to uranium is dangerous without precautions. The effect of uranium depends on concentration, quantity, chemical and physical form, isotopes, etc.
Why is thorium not used in a nuclear reactor?
: Main article: Thorium fuel cycle Thorium, as well as uranium and plutonium, can be used as fuel in a nuclear reactor. Although not fissile itself, 232Th will absorb slow neutrons to produce (233U), which is fissile. Hence, like 238U, it is fertile. Problems include the high cost of fuel fabrication due partly to the high radioactivity of 233U which is a result of its contamination with traces of the short-lived 232U; the similar problems in recycling thorium due to highly radioactive 228Th; some weapons proliferation risk of 233U; and the technical problems (not yet satisfactorily solved) in reprocessing. Much development work is still required before the thorium fuel cycle can be commercialised, and the effort required seems unlikely while (or where) abundant uranium is available. Nevertheless, the thorium fuel cycle, with its potential for breeding fuel without fast neutron reactors, holds considerable potential long-term benefits. Thorium is significantly more abundant than uranium, and is a key factor in sustainable nuclear energy. One of the earliest efforts to use a thorium fuel cycle took place at Oak Ridge National Laboratory in the 1960s. An experimental reactor was built based on Molten Salt Reactor technology to study the feasibility of such an approach, using thorium-fluoride salt kept hot enough to be liquid, thus eliminating the need for fabricating fuel elements. This effort culminated in the Molten-Salt Reactor Experiment that used 232Th as the fertile material and 233U as the fissile fuel. Due to a lack of funding, the MSR program was discontinued in 1976.
What is the final result of radioactive decay?
radioactive isotope
What happens when you mix uranium and thorium?
Who will do that ? The result leads to nothing.
Where does radon gas originate from?
Radon is produced as a result of radioactive uranium conversion processes or thorium. These materials are distributed throughout the earth's crust in traces. As a gaseous element, just the radon can reach into the atmosphere or into houses.
What element will result if two protons and two neutrons are ejected from a uranium nucleus?
If two protons and two neutrons are removed from a uranium nucleus, the new element is thorium. The isotope cannot be determined because the identity of the uranium isotope was not given.
Is uranium a nutrient?
No, Uranium is a rare-ish element whose radioactive isotope is often used in nuclear reactors. ingestion of radioactive elements can result in death

What are the nuclear waste that sometimes is difficult to solve in chemistry?
Radioactive and chemically toxic wastes result from the mining and processing of uranium as well as from storing or reprocessing spent reactor fuel. The tailings or waste produced by the extraction or concentration of uranium from its ore contain radioactive isotopes of uranium, thorium, and radium as well as significant concentrations of heavy metal including chromium, lead, molybdenum, and vanadium. More than 200 pounds of tailings are produced for each pound of uranium. This sandy waste material must be contained in carefully monitored sites known as tailings piles.

Can you eat radiation?
Well you could eat uranium or other or radioactive waste... But as Uranium is expensive and rare, and radioactive waste is deadly, eating radiation would result in killing you. This will not give you super powers like shown in cartoons, but it will end up with you receiving radiation poisoning.
Is plutonium the result of of the alpha decay of uranium?
Plutonium is not related to uranium isotopes radioactive decay; plutonium is obtained by nuclear reactions from uranium isotopes only in nuclear reactors.
What is the decay product of uranium-238?
U-238 is the most abundant (99.3%) of the three naturally occurring isotopes of Uranium. The other two are U-235 and U-234.U-238 decays spontaneously to Thorium-234 by alpha particle emission. This decays by beta decay to Protactinium-234 and then that undergoes beta decay to become U-234.There are many more decay steps by alpha and beta emission. The end result is Lead-206 which is stable.The full path can be found in the Argonne National Laboratories Human Health Fact Sheet, August 2005, titled Natural Decay Series: Uranium, Radium, and ThoriumThis is found at:http://www.ead.anl.gov/pub/doc/natural-decay-series.pdf

Is the atom that remains after disintegration radioactive?
When the uranium atoms fission, the result is a number of different atoms of other elements are formed, these are called the fission products. Some are highly radioactive which means they then decay into other elements, some of which are long lived. The result is that when the fuel is eventually removed from the reactor and stored, it contains various radioactive elements, which is why it is dangerous and has to be stored away from any human contact.
