Contamination Monitors

CoMo 170

Mobile contamination monitor for the high-sensitive and nuclide referred measurement of surfaces with regard to α-, β- and γ-contaminations when handling ionising radiation.

Features

  • efficient, portable contamination monitor with thin-layer plastic scintillation detector completely working without gas-filled or
    gas flow proportional detectors

  • measurement of alpha, beta and gamma radiation with only one detector  (the measuring system automatically detects the existence of alpha radiation)

  • possibility of simultaneous or selective measurement of α- and
    β-/γ-contaminations 

  • easy-to-use (convenient operation with 5 membrane-switch arrays)

  • settings and important measurement parameters are secured
    by a password

  • integrated data storage, optional software for reading out and processing this measuring data 

  • connection facility for different external probes,
    e.g. for dose rate measurement

  • automatic probe identification

  • optional stationary use in wall station with voltage supply

  • a mechanically defective detector foil can be repaired by the user himself (no expensive detector repair required by the manufacturer as otherwise customary for xenon detectors) 

  • avoiding high costs for gas flushing 

Fields of application:

Civil Defence, Authorities, Customs, Nuclear Medicine, Nuclear Technology, Industry, Research

GammaTwin S with contamination probe ABG170

Dose rate meter with alarm function for personal radiation protection when handling ionising radiation and for the detection of the dose rate and local dose.

Features

  • small and handy dose rate meter for the measurement of gamma radiation and X-rays

  • measurand: ambient dose rate equivalent Ḣ*(10) and
    ambient dose equivalent H*(10) (local dose)

  • built-in detector: energy compensated GM tube

  • large, digital indication of measured values on LC-display (backlit)

  • selectable simultaneous or separate indication of dose and dose rate,  additionally analog indication of dose rate (logarithmic bar graph)

  • display of the dose rate history as a search function for the detection of radioactive sources

  • 4 preset dose and dose rate alarm thresholds (on demand adjustment of customised alarm thresholds) 

  • additionally switchable acoustic single-pulse indication

  • automatic and continuous storage of the dose into a non-volatile memory

  • storage of the dose and of set parameters even during battery change

  • permanent self test

  • designed for rough use, housing made of aluminium, protection class IP54 (splashproof)

  • menu-driven user navigation

  • supplied with robust nylon bag

  • optional: external probes, probe cable

  • connection facility for an external probe:

  • 18526 D or ABG170 for contamination measurement (α, β, γ)

  • immersion counter tube ZP1083 D (β, γ)

  • NaI-scintillation probe 2002 for high-sensitive measurements (β, γ)

  • with connected probe:

  • display of measured values in cps

  • display of the pulse rate history graph as a search function for the detection of  radioactive sources or contaminations

  • pre-selectable alarm thresholds: 2x background or 3x background

 

PLEASE NOTE:  

Detecting the personal dose requires a measuring instrument with the measurand Hp(10).
