26 Radioactivity

This page covers the radioactivity section of the course. Take care not to mix units when calculating decay equations. For instance, you may encounter activities given in Becquerel’s and count rates stated in counts per minute; half lives are often quoted in reference works using the most relevant time unit, be it seconds or years.
