The half life of americium-241 is 432,2(7) years.
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
Uranium has the longest half-life element
A half life of o,145 s has the isotope polonium-216.
Knowing the half life of carbon-14 the age of an artefact containing an organic material can be evaluated.
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.
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.
The half life of americium 241 is 432,2 years.
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.
The time to the stage is called the HALF-LIFE of that particular substance.
A non significant quantity because the half life of americium is 432,2 years.
Americium is not necessary for life.
The half life of the most important isotope (241Am) is 432,2 years.
Yes, because the half life of americium 241 is 432,2 years.
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.
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
Americium is strongly radioactive and dangerous for the life and the environment.
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.
