How far is it safe to live from a Weather RADAR? RADAR is one of the most bio-disruptive RF signal you can be exposed to. Weather radars like NEXRAD have very high peak power (hundreds of kW) & large antenna gain, but their average power is far lower. That combination gives a very directive beam that can produce high instantaneous peaks yet a lower time-averaged power density at distance From an Engineering perspective, Safety limits are based on this average power, that's the heating effect over time. But from a Biological perspective, Researchers like Dimitris Panagopoulos argue that it’s the peak pulses, not the averages, that matter. So If you live within 5–10 km of a large weather radar & have a clear view of the antenna (especially at a similar elevation) you’re likely inside a zone of high peak exposure. To fall below Building Biology “Extreme Concern” You’d need to be atleast 50+ km away.
