It needs to be kept somewhere secure to decay, this can take many years for high level waste, or a few months for low level
They are relatively safe, though they likely use a lightly radioactive substance like radium.
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non-radioactive substances are stable.
Those substances which are made of heavy metals are termed as radioactive substances. e.g. u-235...etc
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.
Drinking radioactive substances can be extremely harmful and cause serious health issues, including radiation sickness, organ damage, and even cancer. It is not safe or recommended to consume radioactive materials under any circumstances.
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.
Radioactive materials contain unstable atoms that decay and emit radiation, while non-radioactive materials do not emit radiation. Radioactive materials can be harmful to living organisms due to their ionizing radiation, whereas non-radioactive materials are generally considered safe for everyday use.
H3, Deuterium is radioactive. Uranium and plutonium are radioactive and are used in atomic bombs.
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.
