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.
What is the amount of radioactive material needed to sustain a chain reaction in order to provide useful energy called?
The critical mass.
Matter can't be created or destroyed but could the amounts of some elements in Earth's crust decrease?
There can be a small amount of matter exchange with outer space. On the other hand, some radioactive isotopes can decay, and convert to other isotopes. This will increase the amount of one element, and reduce the amount of another one.
How much radioactive material was leaked during the Three Mile Island accident?
It is estimated that the amount of radioactive gases released from the Three Mile Island Unit II incident in 1979 was less than 481 PBq (13 million curies) and that the amount of Iodine-131 released was less than 740 GBq (20 curies).
If we decrease the amount of force and keep all other factors the same what will happen to the amount of work?
It will decrease in the same proportion.
Determine the amount of radioactive material in a package of radioactive materials you would look at the?
label
Does the amount of radiation you give off depend on what is inside of you?
Yes. Radiation is emanated from radioactive material, so the amount of radiation that someone "gives off" is a function of how much radioactive material they have inside them.
What does a radioactive hazard placard on a vehicle indicate?
The radioactive placard on a vehicle indicates that the vehicle carries some amount or regulated radioactive material.
Does the human body naturally contain a small amount of radioactive material?
Yes.
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.
What type an amount of radioactive material is found in the M43A1 detector?
AM241 250 microcuries
What radioactive material is used in the construction of the bomb?
their is no radioactive material in the construction of any bomb its just a bunch of atoms creating friction and being so excited that they explode in a devistating amount of force.
Can the half life of a radioactive isotope decrease as the isotope decays?
No, the half-life of a radioactive isotope does not decrease as the isotope decays. That half-life remains constant. It's the amount of the substance that decreases as the isotope decays.
What radioactive material is used in the construction of the atom bomb?
their is no radioactive material in the construction of any bomb its just a bunch of atoms creating friction and being so excited that they explode in a devistating amount of force.
Why are bannanas radioactive?
Nearly all living things contain a certain amount of radioactive material, mainly radioactive Carbon. Bananas absorb large amounts of Potassium, therefore also absorbing radioactive Potassium 40.
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.
What are radionuclide bone scans?
Radionuclide bone scans. These scans involve injecting a small amount of radioactive material into a vein. Primary tumors or cells that have metastasized absorb the radioactive material and show up as dark spots on the scan.
