Another area of concern with CRT TVs is the issue of xrays. Throughout the years with kids having there faces so close to small CRT screens health care folks wondered about the amount of xrays children and adults received with daily watching. As years went by, coatings, shields, and internal grids in the CRT itself were designed to try and limit the amount of xray emissions.
Well, that's what happens when you apply 25,000 volts or more to a huge 25" to 36" vacuum tube. Of course, it's nothing in the amount of radiation like you get in commercial xray tube when applying 140,000 volts.
