Description
The portable GM counter is designed and implemented using chipKIT Uno32 microcontroller
board and the Velleman’s K2645 Geiger Muller (GM) counter module. The GM counter
module consists of the GM tube and DC high voltage circuit. The radiation coming into the
GM tube produces a small current due to the flow of electrons and positive ions. The electrons
are then accelerated using high voltage to produce a small current pulse at the anode of the
GM tube. The voltage pulse is obtained by placing appropriate resistor at the output. The
output voltage pulse is used to drive the buzzer. The buzzer makes the sound every time the
radiation enters the GM tube. The output voltage pulse has a peak of about 9 V. The voltage
pulse is then divided using series resistors to obtain one third of the original value. The pulse is
then fed to the input of the chipKIT Uno32 board to count the radiation. The radiation doses in
μR/h are displayed on the LCD module.
