Scintillation Counter And Radioactive Sources
Type of activity: demo
Activity code: N-006
Description:
| 1. Connect as shown in diagram 2. Place radioactive Cs, Co or Na close to scintillation counter 3. Set discriminator level on scalar so gammas shown on CRO correspond to the number of counts Method: 1. Observe the two peaks for Cs137 which occurs at 0.166 MeV; Na22 which occurs at 0.54 MeV; Co60 which occurs at 1.17 MeV and 1.33 MeV 2. Observe the number of gamma ray counts on the scalar |
