What happens to a radioactive material over time?
It disintegrates into its daughter nuclei that are much more stabler than the radioactive nuclei. If a sample of radioacictive material is left it will decay into another element over a period of time. Note that complete decay is not possible. A fraction of the original radioactive material will always remain in the sample.
What is the meaning of radioactive as a safety symbol?
The "radioactive" safety symbol warns you that radioactive material or a radiation producing machine is near the symbol and you should take precautions to ensure that you are not unnecessarily exposed to ionizing radiation.
Why is a sample of radioactive material always a little warmer than its surroundings?
Radioactive material is warmer than the surrounding material because radioactive material is constantly breaking down. When material breaks down, that means that energy is constantly getting released. When energy is released, it produces warmth.
How many years will it take for one half of the original amount of material to decay?
If you are referring to a radioactive material, that will depend on the material. Different things have very different half-lives.
Does quartz give off radiation?
Some varieties may contain radioactive material, whether because the atoms are radioactive themselves or have been irradiated by other minerals.
Can radioactive be recycled?
Yes, there are a number of uses for radioactive material. It depends on the type of radioactive material.
What counts radioactive material?
We often use a Geiger counter to detect and count the decay of radioactive material.
What is necessary for you to be able to explain what happens during radioactive decay?
To fully explain radioactive decay you need quantum mechanics.
What is the name for the emission of rays and particles by a radioactive material?
The name for the emissions of rays and particles by a radioactive material are called radioactive decay. There are many different types of radioactive decay that emit different rays and particles.
If radium and chlorine combine to form radium chloride what is true about the compound?
As radium is radioactive, radium chloride would also be radioactive. Any compounds make with any radioactive material are radioactive, and they cannot be "not" radioactive. Radioactive material doesn't really care if it is "alone" or in compound; it will be radioactive in any case.
What can be naturally radioactive?
The core of the earth is radioactive, as is the sun. Granites, which crystallize from mantle material are commonly slightly radioactive.
What is it called when an unwanted material that contains radioactive atoms is present on another material?
Radioactive Contamination
How old is a fossil that has a radioactive material with a half life of 200 years if there is 25 percent of the original radioactive material left?
400 yrs
Determine the amount of radioactive material in a package of radioactive materials you would look at the?
label
What does the half life of a radioisotope correspond to?
The length of time required for half of a sample of radioactive material to decay
What happens to radioactive materials if you do not use them?
That depends on the radioactive material. But whether you use it or not, the radioactive material will decay into other elements over the course of time. The time it takes for half of the material to decay into something else is called the "half-life". The more radioactive the substance is, the faster it decays. The half-life of a radioactive element can be measured from fractions of a second to billions of years.
Where is radioactive material?
There is radioactive material in any country that has done nuclear tests. In The United States of America there were many tests. These were mostly in Nevada. If you were to get clearance to go to the test site you would see the craters everywhere.
