If you are talking about the game made by VALVe, it is 17 chapters long how long they are depends on how long you take to beat them. It took me 10 hours on easy.
If your talking about the scientific term, It's how long a radioactive material takes for it to decay 1/2 its mass, this varies form each material

How long is berkelium's half- life?
The half life of the most important isotope of berkelium - 247Bk - is 1 380 years.
How long can radioactivity be on uranium?
Radioactivity can persist on uranium for billions of years, as uranium has a very long half-life. The most common isotope of uranium, uranium-238, has a half-life of about 4.5 billion years. Uranium-235, another isotope, has a shorter half-life of about 700 million years.
Why a geiger counter gives a lower counting rate for radioactive material that has a long half life than does with short half life?
A Geiger counter detects radiation by counting the number of decay events that occur. Radioactive material with a long half-life decays more slowly, resulting in fewer decay events per unit time compared to material with a short half-life. Therefore, the Geiger counter will record a lower counting rate for radioactive material with a long half-life.
Is half life of any importance in selecting a radioisotope?
Yes, the half-life of a radioisotope is important in selecting one for a particular application. For example, a short half-life is suitable for medical imaging to minimize patient radiation exposure, while a long half-life is preferred for industrial applications requiring long-term monitoring or storage. It also affects the decay rate and stability of the isotope.
Why is it necessary for a half- life to be long?
Having a long half-life means that a substance decays more slowly over time, which can be beneficial for drugs that need to stay in the body longer for sustained therapeutic effects. It can also reduce the frequency of dosing needed, leading to better patient compliance.
How long have you been in US?
Almost half my life.
How long is radium's half life?
It is about 1600 years.
How long is berkelium's half- life?

What does half-life tell about a radioisotope?
How long it takes for half of a sample to decay to another form.
How long does radiation stay around?
Radioactivity gradually falls in all radioactive materials, how quickly it falls depends on the half-life of the material. The radioactivity of a material with a short half-life will fall alot quicker than the radioactivity of a material with a long half-life.
How long does a half of a 37.5 adepex stay in your system if you only took a half?
the half life of phentermine is 16 to 31hrs
If it were 2 hours later it would be half as long?
If its linear half-life were 2 hours, then yes.
Why a geiger counter gives a lower counting rate for radioactive material that has a long half life than does with short half life?

Therefore, the Geiger counter will record a lower counting rate for radioactive material with a long half-life.
Why is it called half-life of an atom?
The half-life of an atom is how long it takes for half of the atom's mass to radioactively decay. This occurs exponentially; therefore, after 2 of the atom's half-lives have passed, 3/4 of the atom will have decay (half during the first half-life, then half of the remaining mass, or one quarter, during the second).
Were is camp half blood in real life?
Camp Half Blood is on the north shore of long island. Long Island is on the east shore of New York.
