We completely revised our G18410 Geiger Counter Kit. We eliminated the buzzing sound, reduced the size, and made it with a very low battery current requirement. This kit operates f rom one 9V battery (not included) and produces about 400VDC for use with many GM tubes. When radiation is detected the kit emits a clicking sound and flashes a bright red LED. This kit can be used with the LND712 GM tube, Russian tubes such as the CTC-5/STS-5, SBM-10, SBM-19, SBM-20, SBM-21, SI-22, DOB-50, CI-11BG/SI-11BG, CI-3BG and SI-39 to name a few! Size of PC board is only 2.2" long x 1.34". Current drain is about 8mA. Fully assembled Kit (you will need to supply a 9V battery and GM tube). Each Board is individually tested prior to shipping.
