Iodine-129 has a half-life of 15.7 million years and is used in some medical applications. Because of its release in nuclear testing and reactor accidents, it is a potent bio-contaminant and can affect the human thyroid gland.
Its human biological half-life is about 100 days (in the thyroid gland).
60.14 days
The time it takes for half the atoms in a sample of a radioactive element to decay is called the half life.
I believe that term would be 'half-life'
A "Half-Life" is not half of a life, it is half of the life, then half of that life, and then half of THAT life, and so on and so on. For example: Rock has a half life of 100 ---> 50 ---> 25 ---> 12.5 ---> 6.25 ---> and so on. You just keep dividing the life it has, by 2. Another Example: If you take a dissolving vitamin, and weigh it (20g), and put it in water for 1 minute, it should dissolve into ALMOST half of its original weight, into 10g. Scientists often use the method of "Half-Life" to measure the age of a rock or rock formation. Sources: Am a student in science class
The length of time depends on the element and isotope, but the point at which half of the sample has decayed is known as the half-life.
The half life is not calculated, but experimentally measured. The half life of Pa 234 is 6,75 hours.
No. Half Life: Opposing Force does not require neither Half Life nor Half Life: Blue Shift.

No, only Half-Life and Half-Life: Decay.
Most likely Half Life Source
Antibiotics do not have a half life.
You say 'I've missed Half my life' which is short for : "I have missed half my life'
Magnetic field doesnot have a half life. Elements have half life.
Buy Half Life: Source Or Buy Garrysmod a Half-Life 2 Modification and get the addon "Half-Life Rennaisance" Link to Half Life Rennaisance: http://www.garrysmod.org/downloads/?a=view&id=57033 Enjoy!
No. Half-Life: Source runs on the Source engine. The original Half-Life doesn't. You cannot use mods made for the original Half-Life on Half-Life: Source because they run on different engines and it won't work.
No
There is no "Half Life 3" If you're talking about Half-Life 2, then no, but you can get Counter-Strike.
