To determine who must always wear a radiation monitoring badge according to Georgia law, let's carefully analyze each option:
### Option A
Someone who might get more than 25% of the maximum 5 REMS (50mSv) of allowed dose in any calendar quarter.
- Radiation safety regulations generally mandate that individuals exposed to significant levels of radiation must be monitored for safety reasons.
- The maximum allowed dose is 5 REMS (50mSv) per calendar year.
- 25% of the maximum 5 REMS would be 1.25 REMS (12.5mSv) in any calendar quarter.
- If an individual might receive more than 1.25 REMS in any calendar quarter, they must be monitored to ensure they do not exceed safe radiation exposure limits.
### Option B
Someone under 18 years of age operating an x-ray machine that may receive more than 10% of the maximum 5 REMS (50mSv) of allowed dose in any calendar quarter.
- Given that there are additional protections for minors, a person under 18 is generally subject to stricter exposure limits.
- 10% of the maximum 5 REMS would be 0.5 REMS (5mSv).
- If a minor might receive more than 0.5 REMS in a calendar quarter, stricter measures are applied, but it's not explicitly stated that they must always wear a monitoring badge.
### Option C
Someone being trained to operate a portable x-ray machine.
- While training scenarios are often carefully controlled to minimize exposure, specific provisions for wearing a monitoring badge depend on the expected exposure levels.
- This option does not specify any exposure levels, making it unclear whether a monitoring badge is always required.
### Conclusion
Based on the detailed analysis of the exposure limits and monitoring requirements:
- The best answer is Option A: Someone who might get more than 25% of the maximum 5 REMS (50mSv) of allowed dose in any calendar quarter.
Individuals who fall under Option A are mandated by safety regulations to always wear a radiation monitoring badge to ensure they do not exceed safe exposure limits.
Therefore, the answer is:
A: Someone who might get more than 25% of the maximum 5 REMS (50mSv) of allowed dose in any calendar quarter.
