An Etymological Dictionary of Astronomy and Astrophysics

An illness resulting from excessive exposure to ionizing radiation. The earliest symptoms are nausea, vomiting, and diarrhea, which may be followed by loss of hair, hemorrhage, inflammation of the mouth and throat, and general loss of energy.

Etymology (EN): → radiation; sickness, M.E. siknesse, seknesse; O.E. sēocnesse, from seoc + suffix -ness.

Etymology (PE): Bimâri “sickness, infirmity, disease,” from bimâr “sick, infirm, afflicted;” Mid.Pers. vêmâr “sick, ill;” maybe by corruption of Proto-Iranian *amavayā-bara- “bearing illness;” cf. Av. amavayā- “pain, suffering, affliction;” Skt. ámīvā- “pain, grief, distress” + *bara- “bearing;” cf. Av. bar- “to bear, carry;” Mod.Pers. bar-, bordan “to bear, carry, lead.” Alternatively, from *vi-mar-, prefixed *mar- “to die;” cf. Av. mar- “to die;” Mod.Pers. mir-, mordan “to die;” Skt. mar- “to die;” cognate with Gk. emorten “died;” L. morior “to die;”
