No, thermography does not produce radiation. Thermal imaging actually works by detecting the radiation that objects themselves emit. So, you can use a thermal camera phone or a thermal imager with confidence. Here's a breakdown:
- Thermal imaging cameras are essentially special sensors that pick up on infrared radiation.
- All objects with a temperature above absolute zero (-273°C) emit some level of infrared radiation. The hotter the object, the more radiation it gives off.
- The thermal camera detects these variations in infrared radiation and translates them into a visual image, where different colors represent different temperature ranges.
So, the thermal imaging camera acts like a listener, not a speaker. It passively receives the infrared radiation emitted by objects in its field of view and creates an image based on that information.
