Your specialists for non-contact measurements

As an international active and renowned manufacturer, supplier and service provider of measuring systems for the non-contact determination of various process parameters (e.g. density and humidity) mainly in bulk goods (e.g. coal, potassium salt) by means of different physical measuring principles, we have an extensive range of products.

The products have been designed and developed to be used in numerous applications.

Product specification

Radioactivity measurement system for trucks and trains

Description

Der  Zweck der Anlage RMA54 ist es, vagabundierende radioaktive Quellen zu entdecken.

Aus  physikalischen Gründen kommen nur Gamma-Strahlenquellen in Frage, da Beta- und Alphastrahlen z.B. von der Bordwand eines LKW abgeschirmt werden.

Je  nach den Gegebenheiten, aber auch dem Detektorgehäuse wird es bereits schwierig, niederenergetische Gammaquellen, z.B. Am-241 zu detektieren. Grundsätzlich ist dies aber möglich.



Üblicherweise  besteht die Messtrecke aus:
● RD54
Strahlendetektoren

● US-Sensoren als Lichtschranke (optional)

● Industrie-PC mit Auswertesoftware

Application

The  RGI Portal Truck Radiation Monitoring System monitors the entire vehicle online and thus the entire amount of radioactive radiation in the container.

The  detector we have developed is twice as sensitive to radiation substances as other products and can differentiate between different types of radiation sources.

This  "Gateway Vehicle Radiation Monitoring System" is usually installed at the entrance to recycling facilities for scrap iron to determine whether the scrap iron loaded in the truck contains radioactive substances that are harmful to the human body.

These  include e.g. Cobalt (Co-60), cesium (Cs-137) and rubidium (Am-241), which emit gamma rays, which in turn can be detected by the system.

If  gamma radiation has been detected in the material supplied, then a portable radiation detector must be used to find out exactly where the radiating material is.

Technique

Here  are scintillation detectors with the largest possible volume in use, because other detectors are either not available in the appropriate size or have poor absorption behavior, e.g. gas-filled detectors.

The  most commonly used size of 1800x300x50mm is PVT detectors (plastic scintillation counters), which sweep over the area of ​​the loading height and are able to recognize even the smallest of activities.

The  method used by RGI makes it possible to increase the sensitivity of the detectors, so that the signal size is doubled compared to conventional systems.

Because  of their sensitivity, PVT detectors are able to monitor the charge and trigger an alarm if necessary. This can be combined with some other information, up to the photo of a truck.

If  it is also to be determined which nuclide it is, less sensitive but energy-dependent detectors are available with which it is possible directly to record a spectrum of the radiation and to deduce the isotope from the measured energy.

This  measurement is normally carried out when the measurement with the PVT detector has triggered an alarm


Evaluation

An  industrial PC with the appropriate peripherals and software, to become a measuring computer, is used to display the measured values, which nevertheless, offers all the advantages of a standard office PC:
● Connectable printer,
● storage of measured values over 1 year,
● Possibility of entering truck data
etc.
