You may have read about nuclear disasters at sites like 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 mak…
Lab Experiment 5: Half-Life Measurement
Purpose: To demonstrate how to determine a half-life from decay data. To demonstrate the importance of background subtraction. To provide the theory on production of short-lived …
Exponential decay and half life
Exponential decay and half life. Using sealed sources, you can demonstrate most of the properties of alpha, beta and gamma radiation. The experiments in this collection allow students to see their ranges, penetrating powers and, in …
Radioactive half-life describes the time it takes for half of the atoms in a sample of a radioactive substance to decay. The half-life of a radioactive substance is a fixed …
Half-life
In a chemical reaction, the half-life of a species is the time it takes for the concentration of that substance to fall to half of its initial value. In a first-order reaction the half-life of the reactant is …
The `radioactive dice' experiment: why is the `half-life ...
The ‘radioactive dice’ experiment is a commonly used classroom analogue to model the decay of radioactive nuclei. However, the value of the half-life obtained from this experiment differs …
