EMFields RadAware RD1

The RadAware RF/microwave Exposure Alarm

The RadAware RD1 is our personal RF and microwave exposure alarm and was designed using our 25 years experience of EMF/RF measurements and research. The RadAware alarm measures and reacts to signals in the frequency range used by most modern communication systems including most 5G frequencies. The RadAware is designed to be left switched on, monitoring your personal exposure, and alerting you if it rises above your chosen level. Although there are now many meters and monitors that measure RF, there are virtually no sensitive personal RF/microwave exposure alarms.

Further Information

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 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.

Usage

The RadAware can be left on your desk, but it is also small enough to be carried in a pocket or bag. It is a lot more sensitive than other RF measurement instruments and detects more than twice the frequency range.

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. Just turn the adjustment knob carefully 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 instrument is not waterproof and should be covered with a plastic bag if used in the rain.
