Surface Forms

radiometry singular
radiometries plural

Morphology

radiometry = radiation (transparent) = radio + metry

Formed by the combining form 'radio-' (relating to radiation) plus the suffix '-metry' meaning measurement, so the sense 'measurement of radiation' is directly derivable.

Etymology

Radiometry comes from radio-, a part meaning 'ray' or 'beam of light', and -metry, a root meaning 'measure' that you see in the word meter, as in thermometer. So, radiometry literally means 'measuring rays', which is why it refers to measuring light and other radiation.
