Hi,

I am in Manchester UK and have just built an Arduino IDE Geiger Counter based on a kit I bought as ebay item 152426754731 from user impexeris.

The detector tube is an SBT-11A (alpha, beta, gamma), biased at 430V, with the mica window exposed but behind a 0.3mm thick 50% transmission stainless steel mesh.

The detector is usually indoors at home, or at work about 3 miles away. Home cellar reading is 2.4 counts per minute higher than on the upper floors, work reading is consistently 8cpm below home non-cellar reading.

Data is logged via an HC-05 Bluetooth module to either Radiation Logger on PC or plotted on Android using the Visual Logger app,

Andrew.

Thanks for setting up the account. Once I get bored with the usual pitchblende, smoke detector Am source, low sodium salt experiments with paper, aluminium and lead shielding I will leave the counter logging to the site long term, hopefully outside.
