I have a question you might be able to help me with. Do you have any 

information as to risks of somatic or genetic effects of X-Rays from TV or 

Computer monitors. The breaking radiation from the face of a monitor will 

have maximum energy X-Rays in the 20-25 KeV region. An old friend of mine, 

with whom I've lost contact, some years ago put an X-Ray film on a monitor 

screen and determined that in order to get 100 mR per week (the allowable 

limit) one would have to wrap oneself around the monitor and be in contact 

with it. Nevertheless, I have this sense that, with the low prices of LCD 

screens, it might be worthwhile for schools such as ours to consider orderly 

replacements of the older tube monitors. Any thoughts, references or wisdom 

on this?
