Re: X-rays from TV or computer monitors
I suggest reading NCRP Report No. 95, "Radiation Exposure of the U.S.
Population from Consumer Products and Miscellaneous Sources." Chapter 2,
"Electronic Products," includes a description of the applicable standards and
regulations, and survey results.
The opinions expressed are strictly mine.
It's not about dose, it's about trust.
Curies forever.
