Erythema-producing ray
Ultraviolet radiation (wavelengths between 2050 and 3100 A.U.) capable of reddening skin.
-
Delta ray
Highly penetrative waves emitted by radioactive substances. Any secondary ionizing particle expelled due to recoil when a primary ionizing particle traverses through a substance.
-
Characteristic ray
A secondary photon produced by an electron giving up energy as it changes location from an outer to an inner shell in an atom. The wavelengths are characteristic of the difference in binding energies.
-
Central rays
The theoretical center of an x-ray beam. The term designates the direction of the x-ray photons as projected from the focal spot of the x-ray tube to the radiographical film.
-
Cathode rays
A ray composed of negatively charged electrons discharged by a cathode through a vacuum, moving in a straight line and producing x-ray photons upon hitting solid matter. The flow of electrons traversing from the cathode to the anode within an x-ray or valve tube, commonly referred to as the tube current, is quantified in milliamperes.…

Actinic ray
A solar ray capable of producing chemical changes.
-
Raw data
The information obtained during an experiment, before the information has been analyzed or statistically manipulated.
-
Raucous
Hoarse, harsh, as the sound of a voice.
-
Rattlesnake
A poisonous snake of the genus Crotalus. Its bite may produce coagulation disorders.
-
Death rattle
A colloquial term for gurgling noises caused by movements of secretions in the upper airways with inspiration and expiration in dying patients. A raucous type of respiration arises due to the accumulation of sputum (viscous material) in the air passages of an individual nearing the end of life, rendering them incapable of swallowing or expelling…
