What is the annual effective dose limit for a non-NEWS worker?

0.5 mSv 2 mSv 1 mSv 5 mSv

Correct Answer:

1 mSv

Explanation:

Exposure limits differentiate between workers and the general public. For someone who is not a NEWS worker, you’re treated as part of the general public, so the annual effective dose limit is 1 mSv. This keeps any additional radiation exposure at a very low level while still accounting for natural background and other non-occupational sources. The occupational limit, by contrast, is higher (typically around 20 mSv per year) because workers receive training and are monitored to keep their exposure as low as reasonably achievable. The other values would not align with the public exposure standard.
