The clinical introduction of magnetic resonance imaging guided radiotherapy has
prompted consideration of the potential impact of the static magnetic field on biological
responses to radiation. This review provides an introduction to the mechanisms of
biological interaction of radiation and magnetic fields individually, in addition to a
description of the magnetic field effects on megavoltage photon beams at the
macroscale, microscale and nanoscale arising from the Lorentz force on secondary
charged particles.

A relatively small number of scientific studies have measured the impact of combined
static magnetic fields and ionising radiation on biological endpoints of relevance to
radiotherapy. Approximately half of these investigations found that static magnetic
fields in combination with ionising radiation produced a significantly different outcome
compared with ionising radiation alone. MRI strength static magnetic fields appear to
modestly influence the radiation response via a mechanism distinct from modification
to the dose distribution. This review intends to serve as a reference for future biological
studies, such that understanding of static magnetic field plus ionising radiation
synergism may be improved, and if necessary, accounted for in magnetic resonance
imaging guided radiotherapy treatment planning.
