The caution for service techs was because X-radiation damage is cumulative. You would not be harmed significantly by one exposure, but day in and day out would not be so good. Same reason x-ray technicians leave the area to take the picture.

The regulator tube problem was not leaded vs. unleaded glass, but tubes that were constructed crookedly so that the source of x-rays at the anode was not blocked by the metal structure at the bottom of the tube. If a defective regulator was mounted vertically and had no shielding underneath, a kid sitting up close with legs under the set would have his legs in the path of the stray x-rays.
