RADOS RTM661/440
Clearance Monitor
CheckPoint:Waste™ family
7NUC_RTM661-4_Y15-040E_3_FL
Overview of Features Proven measurement methodology in accordance with the rules for free release of material
• total gamma activity measurement using large-volume plastic scintillation detectors in a
4 π measurement geometry
• taking into account all relevant nuclides, even if only one is measurable - fingerprint technique
(nuclide vector)
• integrated weight cells
• activity statements can be related to surface and weight
• background reduction due to measured material self-shielding taken into account
• automatic adaptation of measurement time in accordance to DIN 25482 part 1
Easy operation and clear display of measurement values
• graphic display of activity distribution, including the display of activity position as deviation
from average value in %
• calibrations linked to measurement material (shielding effect, geometry effect, background
reduction, weight, clearance levels) - unlimited number of selectable materials
• display of measurement value in Bq, Bq/g, Bq/cm² (nuclide related with optional nuclide
fingerprint module), weight, material and type
• printer record (optional: label printer)
• large objects can be measured with open door
Real time multitasking operating system QNX
• software with graphical user interface, calibration tool, various optional service applications
(detector test etc.)
Designed for performance in nuclear environments; painted mild steel housing, easily decontaminated.
Customer Benefits Easy handling and maintenance of monitor for quick and routine proof that
• items to be removed from controlled area temporarily or permanently are “clean” of radioactivity
• waste activity is below clearance level
PC based data management
• quick and stable operation through use of industry standard operating system
• ability to network
• various interfaces and optional software add-ons
• TCP/IP ability
A number of operating modes and options allow tailoring of instrument behavior to specific user experience.
references RADOS RTM661/440 monitors have been proven over many generations of RADOS free release monitors.
The RTM661/440 monitor of the CheckPoint:Waste™ family is the ideal monitor
• to supplement whole body contamination monitors at the exit points from controlled areas
in nuclear facilities
• to support small scale, free release of waste materials.
