This would be nice feature in home weather station.

Its minimum detection level is ~200Krad/sec (~2000Gy/sec). You would be extremely dead by the time it tripped.

Could put up one of those websites

[static html page saying "no."]

That does seem pretty intense. To be close enough to get that dose I'd imagine thermal/blast effects would be incredibly high anyways, rendering this chip pretty useless.

1 Gray is an absorbed dose of 1 J per kg, so a 2,000 Gy/s event would mean a typical 75 kg/165 lb human absorbing 150 kW.

This reminds me a bit of the XKCD question about how close you need to be to a supernova to die from neutrinos: inside it.

Or the XKCD question about how much energy would be needed to take the phrase "speed enforced by radar" literally - basically a fairly large nuclear weapon.

You could also try a bhangmeter:
