The half-life of a radioactive isotope refers to the amount of time required for half of a quantity of a radioactive isotope to decay. Carbon-14 has a half-life of 5730 years, which means that if you take one gram of carbon-14, half of it will decay in 5730 years. Different isotopes have different half-lives.
Here is an essay I did for my last Media Studies course (a 200 level paper) on immersion, play, narrative and Half-Life 2. Enjoy! Half-Life 2. Video games, an ever popular form of new media, are often described as just mindless entertainment but there are games out there that let us experience emotions, immersion and extend ourselves in some way.Half-life refers to the amount of time it takes for half of a particular sample to react. Furthermore, it refers to the time that a particular quantity requires to reduce its initial value to half. This concept is quite common in nuclear physics and it describes how quickly atoms would undergo radioactive decay.Half-life marks the time in which isotope mass reduces by half. For example, an isotope has a mass of 10 Grams and its half-life is 5 years, Five years later mass of the isotope would be 5 Grams, in the next five years, its mass would be 2.5 Grams and this procedure will decrease exponentially until the mass is Zero.

In addition, the plants would produce 7,313 tonnes of highly radioactive waste with a half-life of 24,000 years.: It stays in the body for a lifetime, it has a half-life of 28, 29 years and it gets into the bone, it's taken up just like calcium.: Prealbumin, also known as transthyretin, has a half-life of only 1 to 2 days.: This constitutes the main long-term threat in the area as the chemical.
The half-life is important to establish, and research studies usually aim to discover the half-life of a given substance. The length of the half-life usually determines the frequency of the dosing. Thus, a substance with a half-life of 24 hours is usually taken once per day, while another with a half-life of 12 hours will usually require twice per day (BID) dosing.
