A half life is the time for one half of a radioactive material to decay. Different materials have half-lives of different lengths. Some last only a fraction of a second. Some have a half life of hundreds of thousands of years. Unless you tell us what the material is, we can only answer "that all depends."
== == == == its 36,792,000 cuz its 100,800 in a day so u multiply it by how many days are in a year which is 365
Half life has unit. That is unit of time. So it has to be mentioned. Let us assume that half life is 1 year. Okay. Now to know about the mass remaining we have to get the ratio (1/2)^1620. Hence remaining will be 1/(2^1620) * mass at the beginning
The Terbium isotope found in nature (159Tb) is stable. Like all elements, Terbium has radioisotopes, of which 33 have been created to date. 158Tb is the most stable of these, with a half-life of 180 years, 157Tb has a 71 year half-life. 160Tb has a half-life of 72.3 days. Most of the remaining radioisotopes have half-lives that are less measured in seconds, although some have half lives that are measured in days.
First, it isn't very accurate to talk about a radioactive "element"; you should talk about radioactive isotopes. Different isotopes of the same element can have very different behavior in this sense. For example, hydrogen-1 and hydrogen-2 are stable, while hydrogen-3 is not (half-life about 19 years).Individual atoms, in a radioactive isotope, will decay at a random moment. The half-life refers to how long it takes for half of the atoms in a given sample to decay (and convert to some other type of isotope).

6 months fall between February and September: March, April, May, June, July and August. That time span is half of a year.
There are 26 weeks in half a year.
6 months = a half of a year
64 games . . . in a 4 year span
There are six months in one half of a year.

Subtract the year he was born from the year he died. The result is his life span.
A average life span is about 1 year
In half a year there are 6 months. If you ment in one and a half years, then 18 months.
