∙ 12y agoThe activity of a radioactive substance is simply the amount of the substance. (Radio)Activity is measured in curies, with one curie being equal to 3.7 x 1010 disintegrations per second. Often, we deal with smaller quantities, such as the microcurie, which is 2.22 x 106 disintegrations per minute.

What is the relationship between half-life and the activity of the scource?
In general, the shorter the half-life of a radioactive substance, the more active it is. Think about it. Say you have two samples of radioactive material the size of sugar cubes. And let's say they have about the same number of atoms of the radioactive substance in them initially, but the substances are different. Substance A has a very short half-life. Substance B has an extremely long half-life. Let's look at what happens. In substance A, the material with the short half-life, atoms will be disintegrating at a high rate. There will be lots of radiation (with the type being determined by the method of decay), and it will have a high activity. It will be "hot" in the language of the physicist. Substance B will be taking its sweet time decaying. One atom here and one atom there will be decaying, and you could hold it in your hand for a while without doing much damage to yourself. In contrast, substance A would have to be kept in a containment cask to keep people who work around it safe from the radiation. For similar amounts of radioactive material, shorter half-lives mean higher activity. Having read this far, it should be simple and easy to see.
What the meaning of radioactive?
Any substance which is emitting ionizing particles is radioactive. An example is the metal called Plutonium.
How do you determine the half life of a radioactive substance that has changed through radioactive decay After 40 days the original substance left is is one sixteenth of the original amount?
the halflife is 10 days
What affect the half life of a radioactive substance A the mass of the substance B the temperature of the substance C the addition of a catalyst D the type?
the type of isotope apex
What is it when property describes the ability of a substance to change into different substances?
Radioactive decay.
A substance is labeled as being radioactive The substance is?
Radioactive.
What is the difference between a non-radioactive substance and a radioactive substance?
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non-radioactive substances are stable.
Is radioactive waste a pure substance or a mixture?
Radioactive waste is nearly always a mixture but it is possible to be a pure substance.
What is a radio substance?

Yes
Is Pm a radioactive substance?
Pm is Prometheum. All isotopes of this element are radioactive.
Can anyone give you an example of a radioactive substance?
H3, Deuterium is radioactive. Uranium and plutonium are radioactive and are used in atomic bombs.
