According to the provided dose comparison, how does the dose from a single chest X-ray compare to the average annual natural background dose?
Answer
The chest X-ray dose (approx. 0.2 mSv) is significantly lower than the average annual background dose (approx. 3 mSv).
The text indicates that a single chest X-ray delivers approximately 0.2 mSv, whereas the average annual dose from natural background sources is about 3 mSv.
