During a surgical procedure using three minutes of fluoroscopy, an effective dose of 1 mSv was measured. If the fluoroscopy time is doubled, what is the expected effective dose?

Explanation:
The amount of radiation you accumulate during fluoroscopy is roughly proportional to how long the beam is on, assuming the beam quality and geometric setup stay the same. If you spend twice as long under fluoroscopy, you receive about twice the dose. In this case, 3 minutes gives 1 mSv. Doubling the time to 6 minutes means the dose would be about 2 mSv. This assumes the dose rate remains constant; changes in exposure settings or setup could alter the rate, but with the same conditions, doubling the time doubles the dose.
