Are above-ground radars and detectors harmful?

Above-ground detection radar systems use low-power radiofrequency signals to detect vehicles and other road users. When installed and operated correctly, these systems are not considered hazardous to human health.

AGD Systems products are designed to be ultra-low power, helping to reduce running costs, environmental impact and improving safety.

How radar detection works

A radar detector transmits a directional radio signal toward the monitored area. The system analyses the reflected signal to identify the presence, movement, speed, or position of road users.

These signals are a form of non-ionising radiation. Unlike ionising radiation, such as X-rays, they do not carry enough energy to directly damage DNA.

Exposure levels

Human exposure around a correctly installed radar detector is normally very low because:

• The transmitter operates at low power.
• The radar signal is directed toward a defined detection area.
• Equipment is typically mounted above or away from pedestrians.
• Signal strength decreases rapidly with distance.
• Exposure limits include safety margins designed to protect the public.

Current public-health guidance has not established adverse health effects from low-level electromagnetic-field exposure below recognised international limits.

Installation and maintenance

AGD radar detectors should be installed in accordance with the instructions contained within the product manual, including specified mounting positions, orientations, and minimum separation distances.

Conclusion

AGD products do not present a health risk to the public when correctly installed and operated. Normal roadside exposure is within applicable radiofrequency safety limits.
