G2 NUCLEAR PHYSICS


G2.01 GEIGER COUNTER

Various calibrated sources show different decay rates.

G2.02 HALF-LIFE OF BARIUM-137m

Gamma emission from barium-137m is counted for several minutes, and the half-life is calculated. Alternatively, a multichannel analyzer automatically graphs the decay curve for barium-137m.

G2.03 COMPTON EFFECT

Multichannel analyzer shows Compton scattering.

G2.04 SHIELDING

Show how different types of decay require different types of shielding.
