Portable Contamination Monitor with thin plastic scintillation detector for highly sensitive measurement of α-, β- and γ- contamination

Regulations for Radiation Protection Ordinance require that anyone working with unsealed radioactive materials must be checked regularly to see whether work areas, protective clothing or the body surface has become contaminated.

System Features

• The innovative detector technology with thin-layer plastic scintillator provides key benefits over gas-filled or gas flow proportional detectors. These include reduced operating expenses, i.e. consumable gas and high repair costs in the

case of Xenon detectors

• α-, β- and γ-radiation can be measured using one detector.

The measuring system automatically detects the presence of α-radiation. Simultaneous, selective measurement of α- and β-/γ-contaminations is possible

• user-friendly, menu-driven configuration

• important measurement parameters are protected

by pass code number

• calibrated reference nuclide file with integrated auto calibration

• lightweight

• integrated storage of measurement data, software for readout and processing of measurement data

• connection option for different external detectors,

e.g. for dose rate measurement

• automatic detector identification

• fixed location operation with wall mount including of inductive charging, controlling of measurement time and switching between background measurement and contamination measurement.

2 functions – 1 measuring instrument

Use your contamination monitor CoMo-170 also as a dose rate meter. In daily practice of radiation protection, not only contamination monitoring but also dose rate measurement is required. The new contamination monitor CoMo-170 offers the combination for both measuring tasks in one instrument. In the front surface of the CoMo-170 (picture), a Geiger-Müller counter tube is integrated additionally, so that you can measure both contamination and dose rate (e.g. in μSv/h). An economical and practical solution.

Advantages

• Integrated GM-counter tube for dose rate measurement

from 1μSv/h till 20mSv/h

• New dose variable H*(10) according to German radiation protection ordinance

• Energy range approx. 40KeV – 1.3 MeV

• Detector position indicated on front surface

• Simple switch to dose rate measurement in quick menu

• Automatic measuring value display in nSv/h – μSv/h or mSv/h, autoranging-operation

• Digital and analogue measuring value display

• Definable alarm threshold for dose rate measurement

• Measuring values can be stored. Stored measuring data can be printed or transferred to a PC-system for further processing

• Simple operation with user guidance

• Economical solution – less than 50% of the price for a separate dose rate meter.

Make a smear test counter from your mobile contamination monitor CoMo-170. In daily practice of radiation protection, not only direct contamination monitoring with the mobile contamination monitor is required, but also the indirect contamination monitoring by means of taking a smear test sample, especially to find out if the contamination is sticking.

Thanks to the new smear test station you can create a comfortable smear test counter together with the CoMo-170.

Advantages

• Reproducible geometry of the smear test sample to the
  detector system.
• For α- and β/γ-contamination measurements.
• Sample drawer prepared for 60/120mm Ø sample plates and
  smear test swabs on carrying paper (max. 100x130mm).
• Automatic background measurement and subtraction.
• Definable measuring parameters (nuclide, detection surface,
  smear factor, measuring time, alarm threshold).
• As desired entry of a fixed measuring time or automatic
  measuring time calculation according to defined statistical
  error (%).
• Integrated auto calibration routine, 8 definable nuclides.
• Power supply of the smear test counter via adapter, incl.
  charging of the rechargeable batteries in the CoMo.\
• Data storage. Stored data can be printed or transferred
  to a PC-system for further processing.
• Simple operation with user guidance (text hints: e.g. No
  Contamination! Take out sample).
• Low-budget solution.
