c-thermogram

== =__Isotope and Radioactivity__= = = =Name of radioactive isotope/electromagnetic radiation/scientist:= Infared Light which is part of the electromagnetic spectrum.

= = = = =Explanation of interesting facts: (how used/works.experiments/discoveries)= 1. Soldiers use it at night time to see their enemies. 2. The thermogram makes it possible to see stuff with or without visible illumination. 3. It lets you see different temperatures in the body. 4. Firefighters use it to see through the smoke and find people and find the base of the fire. 5. Warm objects stand out better against cooler backgrounds.

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

1. It helps construstion people technicians find heat leaks and improve cooling or heating air conditioning.

2. Power line people use it to find overheating joints and parts.

3. It helps the security services and the military find the bad people.

=3 Disadvantages of using the radioactive isotope/radiation/discovery:= 1. They can only be used to detect direct temperatures.

2. Some images are difficult to interpret correctly when based upon certain things, especially things with weird temperatures, the problem is reduced in active thermal imaging.

3. They have a 2$ accuracy and sometimes worse and aren't as accurate as contact methods.

=Is the radioactive isotope/radiation/discovery still used today? Explain.= Yes it is because its used in pretty much everything. People put it in cars, its used for firefighters and security services and military and power line people use them, its used in alot of careers to figure things out. They are like really important.
