The site also lists a bunch of geiger counter models that their software is compatible with. So I looked one of them up. Mostly I was curious what it would cost to have your own geiger counter.
Quoting the home page of the geigercounters.com website:
We are SOLD OUT!Update 3/25/11, 8:30 A. M. It will be weeks to months before we will have Geiger Counters for sale again - sorry! Read below.
Update 3/17/11, 5.03 A.M. We are no longer accepting orders for Geiger Counters of any sort. If you have already placed an order, it will eventually get filled, in days, weeks, or months, depending on when you placed the order. If not yet filled, your credit card has not been charged, and will not be charged until your order is ready to ship, and you may cancel your order at anytime up until then (do so by email only and put the word Cancel in the subject line). We are generally not answering emails, and if you must contact us, make sure it is urgent, and call us by phone, but please be advised that the time we spend on the phone takes away from order fulfillment. Thanks.
Yikes, looks like the geiger counter folks are going to have windfall profits this year. It also tells me that a number of people don't trust their government or their TVs or the internet, all of whom have put out fairly reassuring messages, i.e. nothing to worry about.
