Extreme radiation hazard?!
Has something very old leaked...?

Well Prince Eugen & USS Pennsylvania were returned to the atoll and sunk there after the Bikini tests - otherwise it doesn't look likely.

I'd guess it 's modern radiation from some of the kit at the RTS test site

Perhaps a test coming up so warming up the radar.

Maybe they're extending the range ......................

A fascinating discovery! I paid several visits to Kwajalein during my early-70s exchange tour, arriving from Johnston Island to the north and returning by the same route. No word on a radiation hazard back then ... and I've made it into my 80s!

That seems to tally with the location of the "Space Fence" Source which appears to be 500m NW of the western threshold. I'd wager that as "the world's most advanced space tracking radar" that's got some oompf behind it. The building appears quite non-descript so it's no apparent whether that is the emitter or whether it's the series of golf balls around the rest of the island.

Edit:

Video

here implies it's an array inside the building, flat upwards facing - quite an interesting design.
