Societal relevant radiation doses.

Type of irradiation	Dose (mSv)
One return flight New York-London	0.10
Typical dose of one year on the ISS	170
Mammography	3
Radiography: chest	0.10
Radiography: abdomen	1.2
CT: head	2.0
CT: abdomen	6–10
CT: pelvis	8–10
Radiotherapy (fractionated)	40.000–70.000
	Mean fetal dose (mGy)
Radiography: chest	<0.01
Radiography: abdomen	1.4
CT: head	<0.005
CT: abdomen	8
CT: pelvis	25
Breast cancer radiotherapy (50 Gy to the mother)	50–150

Doses are whole-body doses, except for those of medical exposure, which are delivered to a specific organ or the embryo/fetus. CT: computed tomography, Gy: gray, ISS: international space station, Sv: sievert. Based on [167, 170–176].
