Scintillation

With respect to Radiation Protection , scintillation is the process where by a material will emit light Photons when exposed to Ionising Radiation . The light photons can be measured with a photo-multiplier tube which will multiply the events to produce an electrical signal or pulse. The pulse can be counted to give an indication of the magnitude o...

Scintillation

Another term used to describe the twinkling of a star. It is caused by the Earth's atmosphere distorting the light from a star, mainly when the star is at a low altitude. Planets may also scintillate when close to the horizon but much less so than stars.

Scintillation

[radar] Scintillation is a fluctuation in the amplitude of a target on a radar display. It is closely related to target glint, or wander, an apparent displacement of the target from its mean position. This effect can be caused by a shift of the effective reflection point on the target, but has other causes as well. The fluctuations can be s...
