Total effective dose: 0.020 mSv.
This dose is equivalent to about 2 days of natural background radiation.
It represents 0.6% of the average annual natural background radiation (3.1 mSv/year).
Doses below 0.1 mSv are considered negligible and carry no measurable individual health risk.
Individual risk depends on age, sex, and genetic factors. Children and women of childbearing age are more sensitive to ionizing radiation.
Next stepAsk your radiologist or technologist if the exam uses the "as low as reasonably achievable" (ALARA) principle and whether a lower-dose alternative exists.
