And in any case, if excess radiation from CRTs promoted tumor formation at all, wouldn't you expect it to be causing retinal tumors, not brain tumors?
I surmised that based solely on my horrible headache-inducing experience with his monitor.
Much more likely due to flicker. Even if it was not bad enough that you were aware of it consciously, flicker from CRT refresh (especially at rates below 75 Hz) was a well-known cause of eyestrain and headaches. Unlike LCDs (which retain the entire image between frames), CRTs start to fade out after each refresh, causing the brightness of the displayed image to pulsate at the refresh rate. CRTs also have a tendency to go out of focus (fuzzy image) and have convergence issues (misalignment of the R/G/B color components), especially towards the corners of the display; this results in additional eyestrain.
I think parts of our body exposed to the elements are more resilient to radiation because they have to be otherwise we wouldn't survive long without getting tumors since they are the ones exposed to all kinds of radiation almost ALL the time.
Any citations to support this? Many carcinogens are inhaled or ingested, so your internal vs. external exposure distinction doesn't really make much sense.
What are the chances that monitor was manufactured by some company that cut costs on properly limiting the radiation exposure of its electron gun?
Possible but unlikely, especially if it was a major brand.
Also worth noting is that CRT computer monitors are generally smaller than color televisions, and will tend to operate their electron guns at lower voltages. This should result in lower emissions.
