Can radioactive be recycled?
Yes, there are a number of uses for radioactive material. It depends on the type of radioactive material.
Is a radioactive standard a radioactive source?
Yes. A radioactive standard is a configuration of radioactive material constructed in a precise way, allowing the standard to be used as a reference when measuring other radiation sources. Standards typically come as solids trapped in a mylar foil pocket, embedded directly in a plastic or electroplated onto a metal disc, or as a sealed liquid solution. Standards are used to calibrate radiation measuring equipment.
How are stratigraphic and radioactive dating different in regards to how they date fossils?
Radioactive dating refers to the process of measuring the age of an object using the amount of a given radioactive material it contains. Relative dating, meanwhile, measures the order of past events, without determining their absolute age.
What counts radioactive material?
We often use a Geiger counter to detect and count the decay of radioactive material.
What is the relationship between radioactive isotope and radioactive dating?
In radiometric dating, the amount of a certain radioactive isotope in an object is compared with a reference amount. This ratio can then be used to calculate how long this isotope has been decaying in the object since its formation. For example, if you find that the amount of radioactive isotope left is one half of the reference amount, then the amount of time since the formation of the object would be equal to that radioactive isotope's half-life.
Radioactive decay of carbon isotopes can be use for?
to allow the correct amount of oxygen to enter and leave the substance
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 are material used for measuring?
Measuring tapes and rulers.
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
