Enclosure suggestion?

[tel0p]

Any pointers for a good site to get an enclosure for this bad-boy? Possibly with stand-offs or the like that line up with holes? Thanks, fun project!

Here's one that just came in today:

There is now an official case for the kit: http://mightyohm.com/blog/2011/10/new-p ... unter-kit/

I'm looking for a waterproof case. I want to mount the geiger counter outside where it will detect anything nasty blowing in on the breeze (or rain). I'm intending to power it from the 3.3v output from my usb-serial dongle, so I only need to run the USB cable back into the house.

My concern is that if I put it into a conventional sealed plastic box -- e.g. http://www.homedepot.com/h_d1/N-5yc1v/R ... ogId=10053 -- then this will prevent all the beta from getting to the tube.

Does anybody have any suggestions?

philip,

The plastic will shield some beta, how much probably depends on thickness and material. The geiger counter at the ATX Hackerspace is in a weatherproof box and it still responds fairly well to beta/gamma sources.

Even if the box does block most of the beta, I think even with just gamma sensitivity you'll still get meaningful data - most radioactive elements emit a combination of alpha/beta/gamma so you should see a rise in your measurements regardless.
