6. Compréhension des lectures
The Irfora FY8817 uses a 5-LED display to visually represent the intensity of electromagnetic radiation. Each LED color corresponds to a specific range of milliGauss (mG) and indicates a relative risk level.
Figure 6.1 : Detailed explanation of the LED indicators and their corresponding EMF levels and risk categories.
Radiation Display Metrics:
- Green (0-1.5mG): Normal level.
- Blue (1.5mG-2.5mG): Low risk level.
- Yellow (2.5mG-10mG): Medium risk level.
- Orange (10-20mG): High risk level.
- Red (20+mG): Ultra-high risk level.
Note: Scientists generally agree that long-term exposure to electromagnetic radiation below 2 mG is considered the safest level.
