Zoals hierboven vermeld hanteert de ICRP een lineaire dosis-effect relatie waarbij een extra kans op fatale carcinogene effecten van 0,005% per mSv wordt voorspeld. Magnetophosphenes are flashes of light that are seen when one is subjected to a changing magnetic field such as when in an MRI. This changing field causes current within the retina or visual cortex resulting in the illusion of light. In one series, 8 out of 1023 people having an MRI experienced flashing lights.
