To determine the average annual radiation dose experienced by a member of the general population, we need to find the most appropriate value from the provided options.

1. Understand the Concept:
- Radiation dose is measured in millirem (mrem).
- The average annual dose is an estimate of how much radiation a person typically receives in a year.

2. Evaluate the Options:
- 0 mrem/year: This value is clearly incorrect as it implies no radiation exposure at all, which is unrealistic.
- 155 mrem/year: This value is relatively low and does not align with typical environmental and artificial radiation sources.
- 310 mrem/year: This value, while plausible, is not the correct average when considering natural and man-made sources.
- 620 mrem/year: This value represents a more comprehensive measure that includes both natural background radiation and additional exposure from medical procedures and other sources.
- 1000 mrem/year: This value is significantly higher than the expected norm for a general population.

3. Conclusion:
- Considering the typical exposure from natural and artificial sources, the average annual radiation dose experienced by a member of the general population is 620 millirem/year.

So, the correct choice from the given options is: 620 millirem/year.
