Assignment:
1. A counting standard whose transformation rate is given as 1000 +/- 30/min is used to determine the efficiency of a counting system. The measured count rate is 200 +/-10/min. What is the efficiency of the counting system and the precision of the measurement?
2. A preliminary measurement made during a short counting time suggested a gross counting rate of 55 cpm. The background counting rate, determined by a 1-h measurement, is 25 cpm. How long should the sample be counted in order to be 96% certain that the measured net counting rate will be within 10% of the true counting rate?
3. What are the models used to describe a sampling distribution? 'What are the differences between them? Which model(s) is used most often in nuclear decay measurement? Why it is valid to use it in nuclear decay measurement?
4. What are the types of error propagation? When do we need to include error propagation in measurement and why?
5. What do false-positive and false-negative mean? Why do they occur?
6. How does a common detector detect radiation interactions?
7. Draw the general configuration of a pulse mode detector. What quantity information does a pulse mode detector give about the source?
8. What is the relationship between absolute and intrinsic detection efficiencies?
9. What is the dead time? What we can do to improve the counting loss?
