OK - expired and Maintenance fees not paid. Lingo - I use 'expired' to refer to the term running out and that was in the old days BEFORE maintenance fees. Hard to learn these new terms and what they refer to!! Maybe 'lapsed' is when the term expires - is it getting foggy in here?

I did see that patent for a radiation detector by Mr. Bordynuik. What was obvious to me is that it was whimsical and that he didn't try to test his invention. He says it can detect alpha radiation but alpha radiation won't make it through the outside case, much less through a photodiode. Alpha particles are heavily charged and heavy--you can block them with a piece of paper. The hazard is in ingestion. I also don't know if photodiode technology has progressed to the point where the photodiodes are that sensitive that they can detect an amount of radiation low enough to where a canary wouldn't serve the same purpose, but if they do make them that sensitive then using it for radiation detection won't exactly be a stroke of brilliance. It's not a mystery to anyone that visible light is only a small range of wavelengths in a large electromagnetic radiation spectrum.
