David Pogue recently wrote on the question of how far you should sit from an HDTV set. He remembered his parents’ rule: sit six feet from any TV set to avoid the radiation.
CRT’s do generate unhealthy radiation, and they are built so that the exposure is mostly from the back. When you sit close to your big screens, you’re still in front and there’s little or no problem. Except for software developers and some other CRT-bound workers.
I’ve often been asked to share a space with another developer. This is often done by having us sit on opposite sides of a desk, so that we are each right behind the other’s CRT. Or I’ve been invited to sit in a row-of-tables arrangement where there’s a CRT’s behind at my back. I’ve always refused these arrangements, but I’m afraid many software developers have not been so lucky.
