The three ways to reduce radiation dose are time, distance, and shielding. Dose builds with exposure time but falls with the square of distance — doubling your distance quarters the dose. Effective dose in millisieverts lets you compare any exposure to everyday references like a chest X-ray or the annual background dose. Educational estimate only.
