1 pc, about 1 5/8 X 1 3/4 " No need to remove from bag. At least 4 grams.
Place the test source as close as possible to the Geiger tube inside your meter/counter/dosimeter. If you don't know where the tube is, check your manual, Google it, or ask the manufacturer.Do notopen, as there is high voltage present!
If this is for a Victoreen CDV-715, or similar survey meter with ion chamber, this will not work for you. Your meter is not sensitive enough.
If you own a model shown in the last picture, please do not bother testing it. They are known fake Geiger counters. Sorry.
This item has evolved over the years, to become what I believe is the safest, most useful, affordable check source available anywhere. It's a tough laminated material that is resistant to breakage. It will not shed, become sticky or crumbly. In a clean environment, the card is tested, inspected, and placed in a new plastic bag with included information shown. Stock images shown. Packaging and sample may look slightly different.
Because of some bad apples lately, I'm forced to refuse sales to anyone with a response of less than 8 interactions. Sorry.
(I will accept less than 8 if you have been an "member" for at least 10 years)
