In general, radiation is about an order of magnitude less effective at

Here's how I figure it:

....

190 TS=92'skin temp (F)
200 QR=1.63E-09*((TS+460)^4-A*(TDB+460)^4)'radiation loss (Btu/h-ft^2)
.....

But one would assume you're not going to be standing out directly as a
radiative body. The outer layer trying to radiate to the environment
won't be but a few degrees warmer than the ambient, certainly nothing
even remotely close to 90F.
