Radioactive waste is nearly always a mixture but it is possible to be a pure substance.
Yes
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.
The most common unit used to express the activity of a radioactive substance is the Becquerel (Bq). One Becquerel is equal to one radioactive decay per second.
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non-radioactive substances are stable.
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.
Radioactive substances radiate energy due to the inherent instability of their atomic nuclei. This instability causes them to undergo radioactive decay, where they release energy in the form of radiation in order to achieve a more stable state.
Radioactive waste is nearly always a mixture but it is possible to be a pure substance.
A radioactive substance emit nuclear radiations.
Yes
Pm is Prometheum. All isotopes of this element are radioactive.
H3, Deuterium is radioactive. Uranium and plutonium are radioactive and are used in atomic bombs.
Radioactive pollution causes cancer.
To determine the decay constant of a radioactive substance, one can measure the rate at which the substance decays over time. By analyzing the amount of radioactive material remaining at different time intervals, scientists can calculate the decay constant, which is a measure of how quickly the substance decays.

In physics, an alpha emitter is a radioactive substance which decays by emitting alpha particles.
