Radioactive waste is nearly always a mixture but it is possible to be a pure substance.
Yes
All the isotopes of uranium are radioactive and unstable.
The average time needed for half of the nuclei in a sample of a radioactive substance to undergo radioactive decay is called the "half-life." This period is a characteristic property of each radioactive isotope and varies significantly between different substances. During one half-life, the quantity of the radioactive material reduces to half of its original amount.
No, the average amount of radiation emitted from a radioactive substance is inherent to the substance's decay process and cannot be changed. The rate of decay is measured by the substance's half-life, which is a fixed characteristic of the radioactive material.
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non-radioactive substances are stable.
Uranium is naturally radioactive.
no
It is radon that we see formed from the decay of naturally radioactive substances in the earth's crust.
A. The half-life of a radioactive substance is determined by the specific decay process of that substance, so it is not affected by the mass of the substance or the temperature. B. The mass of the substance does not affect the half-life of a radioactive substance. C. The addition of a catalyst does not affect the half-life of a radioactive substance. D. The type of radioactive substance directly determines its half-life, as different substances undergo radioactive decay at varying rates.
No, humans are not naturally radioactive. While all living organisms contain trace amounts of radioactive elements, the levels are very low and not considered harmful.
Radioactive waste is nearly always a mixture but it is possible to be a pure substance.
The core of the earth is radioactive, as is the sun. Granites, which crystallize from mantle material are commonly slightly radioactive.
A radioactive substance emit nuclear radiations.
Yes
Yes, alpha decay occurs naturally, that is why radioactive material is dangerous, because we can't simply "turn off" the radioactive decay.
Pm is Prometheum. All isotopes of this element are radioactive.
