Wow. I have not seen a pic of one of those in many moons.

I do not remember those gadgets.

But of course during the period they were out in the public, a lot was already known about the real and potential dangers of exposure to ionizing radiation from x-rays...

And of course there has been quite a bit of evolution in regulation all through the decades.

My first experiences were in June 1978 when I went to work as a summer engineering student for GE Medical Systems, which was once known as the GE X-Ray Department.

I was issued a film badge as part of getting started.

My first assignment was in systems engineering-- final prototype development of a $1 million vascular imaging system. First GE x-ray system that used microprocessors (s) in the control sub-system.

A few years later I was assigned to HW engineering for GE's first digital subtraction angiography system. I got to design (with supervision) a couple of small sub-systems.

At one point our CEO came down to the systems lab... and he got on the table! We did a mock study! I still have the films.

He was a great CEO, and after GE Med he went on to run GE CR&D for many years.

So many memories.... when I arrived at college after that first summer at GE, I learned that the first Dx x-ray ever performed in the U.S. had taken place at my college. Crazy coincidence that I will never forget.

Memories...
