Re: X-rays from TV or computer monitors
I have a hand held spectrometer that has a lower energy level of 10KeV.
When I place the device against the monitor,I am unable to see anything
above background. I a previous life I was involved in instrument design
for CRTs. Leaded glass is often used. I don't think the x-rays get out.
These were only qualitative measurements taken years ago and simply my
two cents added to the pot.
