RADIATION PORTAL MONITOR GAMMA-PIED is used for the detection of radioactive and nuclear materials which are transferred by the people who are crossing the control zone or staying in the controlled site.
Monitor is dedicated to detect gamma radioactive and nuclear materials in the following sites:
- checkpoints in the medical centers, nuclear plants and military warehouses
- at the entrance of the public sites, banks, post offices etc.
RADIATION PORTAL MONITOR GAMMA-PIED 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.
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).
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.
