a unit of measurement of the amount of ionizing radiation absorbed by an object, equal to an energy of 100 ergs per gram of irradiated material (equal to 0.01 gray).
A unit of absorbed radiation dose, 100 rads = 1 joule/kg = 1 Gray
A unit of measurement of any kind of radiation absorbed by humans. One rad is equal to the absorption of 100 ergs of radiation energy per gram of material.

Reactive Airways Disease
Abbreviation for Reactive Attachment Disorder.
Reactive attachment disorder. A disturbance that involves social interactions due sometimes to the result of the neglect of the child's basic physical and emotional needs.
Reactive Attachment Disorder. a condition, resulting from an early lack of consistent care, characterized by a child’s or infant’s inability to make appropriate social contact with others. Symptoms include developmental delays, lack of eye contact, feeding disturbances, hyper-sensitivity to touch and sound, failure to initiate or respond to social interaction, indiscriminate sociability, self-stimulation, and susceptibility to infection.
The merger of various structured techniques with prototyping techniques and joint application development techniques to accelerate systems development.
A concept of developing products designed to give a much faster rollout and higher quality results than traditionally has been the case.
The development of computer systems to tight timescales which would not be achieved using traditional methods of development.
the final of the four compiling programs, it takes the data from VIS and uses it to sort of ray trace light from sources onto textures, and then it assigns each texture its light value so the game engine does not have to ray trace light while you are playing. RAD requires a lot of RAM (128M+) and a lot of CPU/coprocessor and often a lot of time. Large maps and extra lights types square the time required to run.
A fixed size RAM disk that survives a warm reboot.
QRAD is id's official .map editing utility that lights the final .bsp file using radiosity lighting. formerly known as 'light' in Quake I
