Alpha-beta radiation detection unit BDAB-PM1403
Description
The BDAB detection unit is designed to search for sources of alpha and beta radiation, as well as to measure the flux density of alpha and beta radiation.
Operating principle
Operating modes of alpha-beta radiation block (BDAB):
- alpha radiation flux density measurements
- beta radiation flux density measurements
- search for sources of alpha and beta radiation
- programming operating modes
BDAB allows you to set and continuously monitor the threshold level of alpha and beta radiation flux density throughout the entire measurement range, as well as store the set threshold levels of alpha and beta radiation flux density in non-volatile memory.
For convenience when searching or measuring the density of alpha-beta radiation, the BDAB is equipped with a handle, as well as a telescopic rod (up to 1.7 m) to provide access to remote, hard-to-reach places.
Working with PC
Working with a PC is carried out using a special user program supplied on electronic media.
Working as part of a complex device
BDAB is connected to the BDOI (Information Detection and Processing Unit) and BI (Information Display Unit) using a cable (1.5 m) via the RS-485 interface.
In the mode of measuring the flux density of alpha and beta radiation, when the set threshold value of the flux density of alpha and beta radiation is reached or exceeded, the BDOI/BAI produces intermittent sound and light signals and the analogue scale is filled.
Other detection units for working with BDOI
BDG2 – GM detector, gamma radiation detection unit
BDG3 – Csl(TI) detector, gamma radiation detection unit
BDN – He-3 detector, neutron radiation detection unit
