I'm surprised at the low price of Geiger counters lately. Pocket models go for $200 now.
The old '60s style CD handhelds go for about $74 delivered.
A handheld Jameco Electronics -kit- goes for $38 delivered.
Any one of these would instantly settle the fears so many people have about the level of radioactivity in their environment lately. Well, at least the more sensible fears. ;)
-There are some apparently underhanded folks out there, too. This microwave and wall wire detector (Digital LCD Electromagnetic Radiation Detector EMF Meter Dosimeter Tester New) sells for $10.67 with free shipping on eBay.
Also on eBay is this identical item for $113.43, also with free shipping. Same picture, same model, DT-1130.
I have Greenlee's 50-1000V pen version in my toolbox. They're, uh, $4.50 from China.
Here's one from the UK for only $1,662.73
