-
Striatothalamic radiation
Groups of fibers connecting the corpus striatum with the thalamus and subthalamus.
-
Striatomesencephalic radiation
Fibers originating in the corpus striatum and terminating principally in the substantia nigra of the midbrain.
-
Solar radiation
Radiation from the sun; 60% is infrared and 40%; is visible and ultraviolet.
-
Secondary radiation
X-rays produced by the interaction between primary radiation and the substance being radiated. The emission of energy caused by the interaction of primary radiation with a material.
-
Scattered radiation
X-rays that have changed direction because of a collision with matter.
-
Remnant radiation
Ionizing radiation that passes through the part being examined to make the radiographical image.
-
Primary radiation
That radiation being emitted directly to the patient from an x-ray source. Radiation arriving directly from its source without interaction with matter.
-
Photothermal radiation
Radiation of heat by a source of light, as that from an electric bulb.
-
Photochemical radiation
Light rays that penetrate tissues only fractions of a millimeter, are absorbed by cells, and cause physical and biological changes. This type of radiation causes surface heating.
-
Nonionizing radiation
Electromagnetic radiation that does not readily ionize atoms such as that in visible light, ultraviolet light, infrared light, microwaves, ultrasound, and radiofrequency emissions.
