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
What kind of radioactive waste has the longest half-life?
Uranium has the longest half-life element
Why is the half life of polonium 0.145s?
A half life of o,145 s has the isotope polonium-216.
How is half life used for carbon dating?
Knowing the half life of carbon-14 the age of an artefact containing an organic material can be evaluated.
Does the half-life of a radioactive material increase with the amount of material present?
The half-life is a fixed period of time: the average time it will take for one of every two atoms to decay to another isotope or element. So no matter how much of a given radioactive isotope that you start with, only one-half of it will still be that isotope after a single half-life period. Likewise only half of that remaining material will be the same isotope after another half-life period. Of course, some of the atoms will be decaying all the time, so the half-life is only a convenient way to define the quantity at any given time.
What is the half life of americium 241?
The half life of americium 241 is 432,2 years.
What is meant by the half-life of a radionuclide?
It's the time it takes for half of the atoms of a given sample of a radionuclide to decay.
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?
A non significant quantity because the half life of americium is 432,2 years.
How can the element Americium change into the element neptunium?
Americium decays into neptunium-239 through alpha decay. It has a half-life of 7,370 years.
Is americium necessary for life?
Americium is not necessary for life.
How long americium lasts?
The half life of the most important isotope (241Am) is 432,2 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.
Can americium hurt the environment?
Americium is strongly radioactive and dangerous for the life and the environment.
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
Why is americium used in gauges?
Americium 241 is an artificial isotope with a long half life - 432,2 years - and a gamma ray emitter. Being a strong gamma emitter it can be used for gamma radiography of materials and for thickness gauges.
