My Grandfather was around in the early days, had a ham call sign from the early 1930s and was involved in the Manhattan Project as a senior non-scientific engineer.

He was also involved in the development of radar/microwave comms after the war.

He and colleagues did the same - warming their hands in front of microwave antennae.

He developed and later died of some unknown neurological issues related to nerve transmission in the early 1990s. He had been exposed to so many different possible dangers that it's impossible to tell.

After he died I helped clean out and save/donate the double-garage full of ham equipment and home-built telescopes - one was ~.75metre diameter and ~3 metres long, just huge - I was just a teen and let most of it go as my grandmother didn't care by then.

There were also many containers of classified documents, related to WWII and after. Those were appropriately dealt with.

I've always HAD microwaves but have been aware of the issues. I'm a ham as well and still occasionally use the morse key he gave me when I was 7. Still miss him, he taught me so much.
