Where do i get a geiga counter?

[TCSRock78]

Ebay, but first joint a geiger counter group on yahoo so you don't buy a bad one.

I work in the industry. This is just plain wrong. There is radon in everything that comes out of the earth. Gee, how did the caveman every survive living in cave of this stuff??

That is simply idiotic....a sack of potatoes would register the same.

@stoneadvice I checked my bag of potatoes with a CDV-700 with the beta window closed, and it registered 18cpm, and my background is 18cpm. I opened the beta window, and it registered 25cpm, and my background with beta window open is 25cpm. The meter he has is designed for gamma radiation only, and also for surveying high level fields, called a CDV-715. The readings he was getting were around 200 cpm. Since that was gamma only, that is way over background. Get a clue.

@Philios2Glory1 Yes it does. The same amount of radiation that people in Tokyo received from the hyped up fear mongering media reports of global nuclear meltdown. Seriously, the radiation received from your countertops is equivalent to spending a day out in the sun. As long as you don't sleep on your countertops everyday and carrying them around with with you in your pocket, you will be fine.

I have a question, we Just brought a granite top slab for our kitchen, does that mean the slab we brought gives off radiation?

@vipervnm "Too much is anything over 5000 mREM per year."

Could you cite your sources?

[DrMotorDude]

You ARE getting Gamma through the box, are you thinking of Beta?

[QualityMarbleAndTile]

Cold Spring Granite (granite slab supplier and distributor) will let you test your slabs of you wish if you have any doubts.

[QualityMarbleAndTile]

I have tested about 150 different granite colors, came across NOTHING. I really wanted to check on radon on granite but nothing came up and that was with three differnt ways of testing. This Geiger counter has this weird noise everywhere and I wouldn't take it so accurate and serious.

[memo92306]

The soil around your house emits more radon. Please check scientific fact.

[lukevash]

lol thats nothing to worry about

I was wondering if the granite yard here willingly let you test the samples, or you just brought the LENi in, and did it, unbeknownst to them.

We want to have granite put in, but I am going to insist they let me test if first. I just ordered a LENi, and an Inspector Alert, they are on the way.
