Radiation Monitoring System

The monitors of the system RMS 250 are designed

for  xed installed, safety related measuring channels

classi ed by the German nuclear regulations

KTA 1501 ff and KTA 3501 or similar international

regulations.

APPLICATIONS

• Dose rate monitoring according to KTA 1501

and KTA 1506

• Monitoring of radioactive aerosols, iodine and

noble gases according to KTA 1502 and KTA

1503.1

• Stack monitoring for post accident conditions

according to KTA 1503.2

• Liquid monitoring according to KTA 1504

• Dose rate and activity monitoring for research

reactors according to KTA 1507

• N-16 monitoring for detection of steam generator

leakages according to KTA 3501

FEATURES

Calibrated monitors for radiation protection and
process monitoring assembled with qualifi ed
components:

● Detectors, measuring vessels, lead shieldings

● Cables, signal procesing, test equipment
