Nothing radioactive here

I have been searching without any success. I have low end (50 mr/hr), high range (0 - 500 R/hr) and mid range (0.2 mR/hr to 200 R/hr) radiation detectors. I have checked everything in the house, even the lead bricks I bought off Ebay. The only items exhibiting any radioactivity at all were, a radium clock dial, a smoke detector and a sample of Cesium 137 (owned for calibration purposes). Nothing puts out more than 1.7 mr/hr. Even my geology specimens are totally quiet and harmless (unless thrown of course).

I suppose I should be glad, but it is somehow disappointing to know nothing is dangerously radioactive in my home.

My uncle was a lab technician and gave me one that was not being used.
I too couldn't find anything useful to test until I found a YouTube video showing how to modify it to receive different signal wavelengths.

Ken -
Just for kicks, try it on beer.

Beer is legally required(!) to have a small amount of detectable radiation to prove the alcohol therein came from an agricultural source - i.e. grain.

@Ken, next year would be the Olympics. I am welcoming you here in Japan just so you can test your gadget.bouquet
