Black body radiation plots at the source of the heat — the filament. Just how much sub micron energy gets past the glass of the bulb?
Also that’s not a plot of scanner output versus output at one inch from the light bulb, which would be helpful get a ballpark estimate of the risk of the Thz band.
You also mentioned florescent lights, there are a number of phosphors, and spectrums resultant. What level of Thz radiation comes out of them?
Ever used an infrared massager? They emit in the far infrared range 4 - 1000 microns(4mm-1000mm)-just above what we are discussing. I wonder how long that method of therapy has been around?
Intrinsically safe, in my and most everyone's opinion, but to each his own.
Ah, heck. Let's just run everyone and their gear thru one of these.
Might be fun to go watch, even.
