Radiation

Folks are working on their radiation labs, looking at the impact of distance and shielding on the intensity of radiation experienced at a location. Not surprisingly, both increased distance and shielding lowered the radiation intensity and the relationships were nicely exponential. Tomorrow, some groups will be finishing up these labs and others will be taking on a new concept - half-life. We'll use a discharging capacitor to give us a nice model of nuclear decay and use the resulting curve to examine the half-life of the capacitor.
