A small unit that measures radiation equal to one thousandth of a rem

is the full written form rather than the short abbreviation

Surface Forms

millirem singular
millirems plural

Morphology

millirem = rem (transparent) = milli + rem + milli

Formed by the productive metric prefix 'milli-' meaning one thousandth plus the unit 'rem', so the meaning is directly 'one thousandth of a rem'.

Etymology

The word millirem comes from milli- meaning 'one thousandth' and rem, an old unit for radiation. Think of it like millimeter: a millirem is a tiny part of a rem, which is why it names a small dose of radiation.
