B+Thermogram

=__Isotope and Radioactivity__= = = =Name of electromagnetic radiation:= Thermogram = = = = =Explanation of interesting facts: (how used/works/experiments/discoveries)=
 * 1) It is a test that creates infra-red images that show the different temperatures of different parts of the person's body.
 * 2) Can be used to detect abnormalities, such as tumors, in a body. Currently it is mostly used to detect breast cancer.
 * 3) A thermographic camera looks the same as a regular camera or camcorder.
 * 4) Some physiological activity (particularly responses) in warm-blooded animals can be monitored by thermographic imaging.
 * 5) Also is used by firefighters to see through smoke, when thermal insulation becomes faulty construction technicians can see heat leaks, and power line technicians us thermal imaging to locate overheating joints and parts to predict a failure in the system, which can then be repaired to eliminate potential hazards.

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

1. Can detect a tumor or other disease, which can then be treated quicker to prevent further growth or infection.

2. It is a non-contact, non-destructive testing method.

3. It can be used in areas where it is inaccessible for other tests or methods, to measure or observe.

=3 Disadvantages of using the radiation/discovery:= 1. Good quality cameras are quite expensive.

2. Measurements can be altered by things consumer, applied, or reflection from surroundings.

3. Persistent abnormal thermograms create a 22 times higher risk of future cancers.

=Is the radiation/discovery still used today? Explain=

Yes. It is mostly used to detect breast cancer and other cancers. It is also used to detect problems in other technologies, buildings etc.
