RADIATION PORTAL MONITOR GAMMA-SCRAP is designed to detect and search gamma emitting radioactive sources in scrap industry. The detector is easily operated requiring only an understanding of basic parameters and settings for proper operation. The core element of the system is the system of few very sensitive scintillation detectors CsI(Tl).
RADIATION PORTAL MONITOR GAMMA-SCRAP belongs to new generation of extremely sensitive and power safe gamma radiation detectors. When the device is ON, the detector continuously monitors environment for radiation and alerts the user with an audio or visual alarm if a radiation source is detected.
CONSTRUCTION
The detector is equipped with Safety Alarm threshold to alert user when immediately dangerous for life radiation level is reached. When this threshold is exceeded, the instrument will produce easily distinguishable periodic audio and/or visual alarm with one second interval.
Alarm levels in the Search Mode are derived from the ambient background. When the instrument runs through background calibration, it acquires a background reading and calculates the alarm levels automatically based on the value of n coefficient set by the user.
In case of radioactive material detection it is suggested to use additional hand-held indicator to localize the radioactive source or contaminated material (RADIATION INDICATOR).
Scintillation signalization which is the core element of the system has the ITRAP certificate, which confirms the compliance of technical parameters with the requirements of IAEA in Vienna (INTERNATIONAL ATOMIC ENERGY AGENCY).
CONSTRUCTION
Scintillation signalisator is the core element of the system. The type of scintillator is choosen according to the application:
- CsI(Tl),- NaI(Tl),- plastic.
Moreover, the device consists of:
- detector controller,- detector power supply block,- data block,- relay output/input.
It is possible to steer or stop the choosen device using the alarm signal (i.e.: conveyor, door, acoustic-optic signalisator).
In case of normal work mode return one should send the cancelling alarm signal from PLC controller.
