luco-, luc-, luci-, lux, -lucence, -lucent

(Latin: light, lights, shine, shines, shining)

roentgenolucent
Radiolucent, allowing x-rays to pass through. A dark area appears on the radiograph.
roentgenoluminescence
Emission of light that is produced by X-rays.
semitranslucent
Slightly clear; transmitting light in a slight degree.
Sic luceat lux vestra.
May your light thus shine.

Motto of Buxton College, U.K.

Sit lux.
Let there be light.

Motto of Tarkio College, Missouri, USA.

Sol lucet omnibus.
The sun shines for everyone.
sonoluminescence
In physics, a luminescent phenomenon that is produced in certain materials by high-frequency sound waves or phonons.
sonoluminescent
The emission of short bursts of light from imploding bubbles in a liquid when excited by sound.

A sonoluminescent result may, or may not occur, whenever a sound wave of sufficient intensity induces a gaseous cavity within a liquid to quickly collapse.

sonoluminescently
A reference to, or descriptive term for, the emission of short bursts of light from imploding bubbles in a liquid when excited by sound.
subluminal
Having or being a speed less than that of light.
superluminal
Having or being a speed greater than that of light.
thermoluminescence
1. Luminescence resulting from exposure to high temperature.
2. The phenomenon in which radiant energy absorbed by certain materials, such as lithium fluoride, is later released in the form of light when these materials are heated.
thermoluminescent
1. A phenomenon in which certain minerals release previously absorbed radiation when moderate heat is applied.
2. The glow or emission of light produced by the application of heat; used to monitor the radiation dose to which a substance has been exposed.
3. The production of light by a substance when its temperature is increased.
thermoluminescent dating
In archaeology, a method of dating by measuring the rate of release of light energy from an object; often used to establish the date when a pottery artifact was last heated in antiquity.
thermoluminescent dosimetry, TLD
1. A method of measuring the ionizing radiation to which a person is exposed by means of a device that contains a radiation-sensitive crystalline material; especially, to a hazard inflicting cumulative impact over long periods of time, or over a lifetime.

The material stores the radiation's energy by changing the structure and then when the material is heated at some later time, it releases the energy as ultraviolet or visible light.

The light emitted is detected by a photomultiplier tube that generates an electric signal in which the magnitude reflects the amount of ionizing radiation originally received.

2. The determination of the amount of radiation to which a thermoluminescent material has been exposed.

This is accomplished by heating the material in a specially designed instrument which relates the amount of luminescence coming from the material to the amount of radiation exposure.

Ionizing radiation, such as x-rays, alpha rays, beta rays, and gamma rays, remains undetectable by the senses, and the damage it causes to the body is cumulative, depending on the total dosage received.
