DT116 Geiger-Muller Counter

Type:
Radioactivity

Range:
0-1024 bq

Sensor Description:

The DT116 is equipped with built in GM-tube and integral power supply. This will allow direct connection to the input of the MultiLog that will also provide the 5V required operation voltage. The DT116 is equipped with a power indicator, indicating that an operational voltage is supplied to the unit- a yellow LED. Furthermore, the unit is also equipped with a buzzer emitting an audible signal when each pulse is recorded. The DB116 is sensitive to Alpha, Beta and Gama radiation.

How it works:

The Tube Window is made of a very thin and delicate material which is easily destroyed. For this very reason, it has been equipped with a protective cap which may be left on it most cases except when measuring Alpha radiation. The cap is provided with venting hole to avoid vacum when removing it , or opposite, when mounting it again. Note: It is of the utmost importance that the venting hole is uncovered when mounting or removing the cap.

Calibration:

The DT116 is shipped fully calibrated. Further calibration is not needed.

Plateau:

The Plateau is the part of the diagram where the number of counts per second is (almost) independent of the voltage The graph in the right expresses the radioactivity magnitude versus the distance between the radioactive source and the Geiger Muller sensor.
