radiometryn.

Brit.

/ˌreɪdɪˈɒmᵻtri/, U.S.

/ˌreɪdiˈɑmətri/

Origin: Formed within English, by compounding; perhaps modelled on a French lexical item. Etymons: radio- comb. form², -metry comb. form.

Etymology: < radio- comb. form² + -metry comb. form, perhaps after French radiométrie (1878). Compare earlier radiometric adj. 1 and later radiometer n.² 1b, 2, radiometric adj. 2.

The detection and measurement of radiation, esp. electromagnetic radiation; the use of a radiometer.
