This is a set of fine quality nuclear radiation detect module unassembled parts set, plug it and you can directly measured nuclear radiation. For the detection of 20mR/h-120mR/h of gamma rays and 100-1800 off variables/points of the soft beta ray. You can have a try.

Features:
5V power supply, or 3 * 1.5V battery; 4 * 1.2V battery, current: 30mA - 120mA.
For the detection of 20mR/h-120mR/h of gamma rays and 100-1800 off variables/points of the soft beta ray.
Equipped with sound alarm and light alarm function.
Interrupt the output interface, through this interface can be connected to the microcontroller and then displayed on the LCD.
Supports most of the Geiger tube: M4011, STS-5, SBM20, J305, etc. (the 330-600V operating voltage of the Geiger tube can be supported).
Support the computers (PC) data acquisition, Matlab analysis and processing.
