Question

The pulse that is counted in a Geiger tube is caused by a

rise in voltage from ions arriving at the anode

drop in the voltage from ions arriving at the anode

rise in voltage from electrons arriving at the anode

drop in voltage from electrons arriving at the anode K.

6. In a Geiger tube the total time taken to create a pulse and then let the electrons recombine with the ions to again form a neutral state is about

1 s

30 s

300 s

10,000 s

7. A typical operating voltage for a Geiger counter is about

5 V

50 V

500 V

5000 V

8. In this laboratory the half-life of 137Ba will be determined by measuring

the number of atoms left as a function of time

the activity that is constant

the activity that decreases as a function of time

the activity that increases as a function of time

Explanation / Answer

drop in voltage from electrons arriving at the anode

1 s

500 V

the activity that decreases as a function of time
