The RadAware RD1 Pocket RF Radiation Alarm for personal use

The RadAware RD1 is our Personal RF/microwave exposure alarm. Although there are now many meters and monitors that measure RF, there are virtually no sensitive personal RF/microwave exposure alarms.

The RadAware is designed to be left switched on, monitoring your personal exposure, and alerting you if it rises above your chosen level. It can be left on your desk, but it is also small enough to be carried in a pocket or bag. It is thousands of times more sensitive and detects more than twice the frequency range of other RF alarms we have seen. We designed the RadAware using our 25 years experience of EMF/RF measurements and research.

All of us are constantly being exposed to increasing levels of pulsing microwave signals from smart phones and their base stations, WiFi, DECT cordless phones, tablet PCs, games consoles, Smart Meters, supermarket checkout systems, etc. Now we also have the 'Internet of Things' (IoT) sources that include most modern fridges, freezers, cookers, washing machines, etc. in your home. These are hidden microwave radiation sources that you will not easily be aware of and it is not practical to continously take readings.

The RD1 alarm automatically monitors for microwave RF exposure and alerts you when you are being exposed.

The RadAware alarm measures and reacts to signals in the frequency range used by most modern communication systems including most 5G frequencies. The RadAware measures the peak RF / microwave level 128 times every second. A separate green flashing LED above the on-off switch shows that it is working.

Exposure levels are shown on three LED lights and are also indicated by six different audible alarm sounds which can be switched off. The RadAware runs off an alkaline 9V PP3 battery. If used continously, the battery will last for about 3 weeks provided that it is not regularly sounding an alarm when the battery life will be shorter. There is an audible low battery warning. We suggest that people who want continuous monitoring use rechargeable batteries or a mains adapter (9 volt DC, available separately).

The sensitivity can be adjusted to suit your personal requirements and also the typical exposure levels in your environment by carefully turning the adjustment knob from very sensitive to least sensitive. It is normal to adjust it so that it is not continuously sounding the alarm.

The actual alarm ranges are given in the Technical Specifications Table. The relative differences between the alarm levels are shown in the table below (10:1 for signal strength; 100:1 for peak microwave power density).


The instrument is not waterproof and should be covered with a clear plastic bag if being used in rain.

Lloyd Burrell (ElectricSense) has done a 9 minute independent YouTube review of the RadAware.

The RadAware Mains Power Supply Adapter

If you want continuous monitoring and you have mains power available, then you can use our mains adapter instead of batteries. This has a connector that you attach to the internal RadAware battery connector instead of the 9 volt PP3 battery. If purchased with the RadAware at the same time, then we remove a small piece of the battery cover to allow the wire to pass through. If ordered separately, the instructions explain how you can do the same thing yourself.

Please note that the RadAware sounded the alarm continuously when used with all the switched-mode mains adapters that we tested, due to the RF signals passing up the supply lead. Our adapter uses a traditional 50/60 Hz transformer and works well with the RadAware.

Please note that the mains adapter weighs about 390g for postage/carriage.
