What is meant by the half-life of a radionuclide?

The half-life of a radionuclide is the time it takes for half of the radioactive atoms in a sample to undergo radioactive decay. It is a characteristic property of the radionuclide and can be used to determine the rate at which it decays.


What is the half life of americium 241?

The half life of americium 241 is 432,2 years.


If the half-life of a radionuclide is 1 month is a sample of it completely decayed after 2 months?

No, it is not. If a radionuclide has a half-life of 1 month, half is gone after 1 month. Half of the half that is left will be gone after 2 months, and that will leave 1/4th of the original amount left after the second month.


When 50 percent of a radionuclide is gone?

The time to the stage is called the HALF-LIFE of that particular substance.


How much americium is left in a smoke alarm after 10 years?

Could a homeowner install a smoke detector containing americium-241 and use it for decades if he replaces the battery once a year?

Yes, because the half life of americium 241 is 432,2 years.


How can the element Americium change into the element neptunium?

Americium can change into neptunium through a process called alpha decay. During alpha decay, an alpha particle (helium nucleus) is emitted from the nucleus of the americium atom, resulting in the transformation of the americium atom into a neptunium atom.


The rate at which radioactive decay occurs is given in half life explain the term and give the half life of a few substances?

Half-Life is the time taken for the radioactiverty of a source to half. For example Americium-241 (commonley used in smoke alarms) has a Half-Life of 432 Hope this helps Dynofly :-D
