Thermography

=__Isotope and Radioactivity__= = = =Name of radioactive isotope/electromagnetic radiation/scientist:= Thermography = = = = =Explanation of interesting facts: (how used/works.experiments/discoveries)=
 * 1) It is a type of imaging science that uses infrared light energy.
 * 2) Thermographic cameras detect radiation (through heat), producing images called thermograms.
 * 3) Radiation is emitted by anything at or near room temperature (according to the black body radiation law).
 * 4) It is very often used by military and security services, among other things.
 * 5) Thermographic imagers change the heat energy given off in infrared wavelengths into visible light shown on displays.

=3 Advantages of using the radioactive isotope/radiation/benefits of discovery=

1. Thermograms show visual images, so the temperatures in a large area can be observed and compared at the same time.

2. You can see and catch moving targets because cameras/displays show the subjects in real time

3. In areas that are or might be dangerous or inaccessible to other methods, thermography can be used to measure or observe.

4. It is a non-destructive test method, which is useful and helpful in science experiments.

=3 Disadvantages of using the radioactive isotope/radiation/discovery:=

1. Thermographic cameras can cost a lot depending on the level of quality.

2. It is difficult to get an accurate temperature using thermographic cameras because they tend to detect surface temperatures.

3. Higher end models and versions are often restricted from export.

=Is the radioactive isotope/radiation/discovery still used today? Explain= Yes, thermography is still used currently in many aspects. For example, use by the government and airport staff have increased due to the use of thermal detection of the H1N1 Swine Influenza. Firefighters also use thermographic detectors and cameras to find the bases of fires, see through smoke, and find people in danger. Another way thermography is used is by power lines maintenance technicians. Faults that cause overheating in joints and parts can be found using thermogrphic detectors. Also, a thermographic imaging system was installed into the 2000 Cadillac Deville.
