A Simple Example of Radioactive Dating
Brown, Todd
Physics Teacher, v52 n2 p115 Feb 2014
Although nuclear half-life is vital to physics and physical science, and to sensitive societal issues from nuclear waste to the age of the Earth, a true lab on half-life is almost never done at the college or high school level. Seldom are students able to use radioactivity to actually date when an object came into being, as is done in this experiment. The procedure described here uses a radiation monitor and at least two [superscript 60]Co sources of different ages: the students collect data and are able to calculate how much older one source is than the other. The theory and technique involved make this an easily transferable lesson when studying carbon dating.
