Carbon Dating-P4

Key equations and derivations. Half Life : the time taken of a radioactive isotope to decrease to half the initial mass. Activity : the number of nuclei of the isotope that disintegrate each second. Decay Constant : probability of decay each second per unit time. Argon Dating : using the proportion of potassium to daughter argon to establish the age of a rock gripping stuff, I know. Corrected Count Rate : the measured count rate of a radioactive source, corrected for background radiation. Rate of disintegration. Note that the introduced negative sign is to denote a decay, whereas activity above. Decay Constant.

Like a seemingly boundless number of chemistry and physics terms, the word “radioactive” has been co-opted by the general public to mean something other than what physical scientists mean. In everyday English, to describe something as radioactive is to imply that getting near it is a bad idea because whatever you’re talking about has been irreversibly stricken a contaminating force.

In reality, radioactivity can indeed be dangerous to living things in certain forms, and it probably can’t be helped that many people reflexively associate the term with unwanted images of atomic bombs and “leaky” nuclear power plants. But the term encompasses a host of physical events, many of them agonizingly slow to unfold but also vital to scientists in a number of ways.

Key concepts Energy Radioactivity Exponential decay Odds. Introduction One way of creating energy is with nuclear reactors. These plants are generally safe, but occasionally there are accidents in which dangerous radioactive material escapes. You might have read about nuclear disasters, such as those at Chernobyl, Three Mile Island and Fukushima, in the news or in a history lesson. Disasters like these can take years or even decades to clean up, and make it unsafe for humans to live nearby for even longer.
