Old TV x-ray exposure

right?

Been fine so far haven't we? If I start glowing green, then I'll worry. The radiation from these sets is nothing compared to the things I've done and ingested in my life. I wouldn't worry too much. Like others have said, just limit exposure, use common sense and stay away from the 6BK4!

The dose we get from a dental x-ray or a CAT scan is much higher than what we'd ever accumulate from watching TV. We get dental x-rays because the benefits outweigh the risks. Exposure to x-rays changes the probability that you'll develop a cancer or other issue. It's still a roll of the dice. There's no clearly defined point at which you go from being ok to not being ok.

Some of the risks we encounter are regulated. Others are left up to us to decide about.

There are lots of things in life that entail some risk. Nearly every activity. We make our own risk/benefit evaluation when we choose to participate in some activity.

I wouldn't use a running CRT as a pillow to sleep on, but I'm not about to stop watching TV because of a nearly unmeasurable increase in risk.

For me it's not just the length of my life but also the quality of that life. Gotta have a balance between the two.

I like well-done (almost burnt) toast. Years ago, someone told me it was likely to increase my chances of getting cancer.

Hmmmm


well maybe one of you with a crt screen can tell me what the HV is on this schematic. I have this TV but always worried about the X-rays. But it has glass shielding and if the Hv is low enough I really won't be worried.

Oh and why do I think yo can read it if I can't??

Thats because when I printed this, and tried reading it really hard, I just couldn't make out the value of one capacitor.(on my lcd monitor)

But then one day I scrolled by the schematic on my Front Projection Display(CRT) and It was clear as day. .0047 MFD.

So maybe one of you with a far superior CRT monitors can take a peek at it for me??

Cheers,

V18 V19 and V20 are your HV tubes (sweep, rectifier and damper). At least V19 and 20 should be inside of the HV cage, which is more than enough shielding for them. I wouldn't worry, though. Sitting close enough to the set to get anything close enough to a dose of rads would damage your eyes from severe strain before that would happen.
