thermo-, therm-, thermi-, -thermia, -therm, -thermal, -thermic, -thermias, -thermies, -thermous, -thermy
(Greek: heat, heating, heater, hot, warm)
The term heat is employed in ordinary language in different senses. Some scientists distinguish four principal applications of the term:
- Sensation of heat.
- Temperature, or degree of hotness.
- Quantity of thermal energy.
- Radiant heat, or energy of radiation.
2. A system in which the application of heat shrinks the collagen of the corneal stroma and flattens the cornea in the area of heat application. This tends to make the eye less myopic.
2. The study of the motion or motive power of heat.
2. Unstabilized or destroyed when exposed to high temperatures.
3. Easily altered, destroyed, or decomposed by heat.
2. The study of heat and heat associated phenomena.
By measuring the amount of thermoluminescent gleaming that is given off, the duration of exposure to radiation can be determined; so, it has been used to determine the age of various minerals and archaeological artifacts.
Because of her work in the X-ray department at the hospital, Ms. Smith frequently used the thermoluminescent dosimetry device to ensure that she remained uncontaminated by the radioactive emissions.2. The determination of the amount of lucidity to which a material has been exposed: Usually thermoluminescent dosimetry 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 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 of thermoluminescent dosimetry received.
Dr. Jonas used the thermoluminescent dosimetry concept to obtain an estimation of the amount of radioactive elements to which the X-ray staff might have received.
2. Chemical decomposition by heat.
3. The breakdown of a substance induced by heating it.
2. A reference to an agent promoting heat dissipation.
2. Physical therapy technique using both heat and massage.
