Frequently asked questions
What type of detector should I choose for the radiation I am monitoring?
The choice starts from the type of radiation and the quantity to be measured. For gamma dose rate, ionisation chambers, Geiger-Müller tubes or scintillators are used; for surface contamination, probes with a thin window are needed, which let alpha and beta radiation through; for neutrons, helium-3 or boron-10 counters with a moderator are used. If the radionuclide has to be identified, not just the presence of radiation detected, you need a spectrometer. Describe your application and we will help you narrow down the options. For applications with several types of radiation, several detectors are usually combined in the same system, each in its own range.
What is the difference between a radiation detector and a gamma spectrometer?
A simple detector, of the survey meter type, shows the intensity of radiation as a count rate or a dose rate, without saying which radionuclide it comes from. The spectrometer also measures the energy of each photon, and the lines in the spectrum allow radionuclides to be identified, because each has characteristic energies. For routine checks, a detector is sufficient and simpler to use. When you need to know exactly what material is present, the spectrometer becomes necessary. A spectrometer is a larger investment and requires analysis software, so it is worth deciding beforehand which decisions will depend on the result.
What details should I include in a request for quotation for radiation detection equipment?
Specify the type of radiation to be monitored, the quantity to be measured (dose rate, personal dose, contamination, spectrum), the expected range of values and the conditions at the place of use, such as temperature and humidity. State the number of instruments or measuring points and the integrations required, for example outputs to an alarm system. If you are replacing existing equipment, send the make, model and code. With this information we check the specifications and prepare a quotation adapted to your need. Technical documentation and specifications are checked before ordering, so that nothing is discovered late, at commissioning.
How long does delivery of radiation detection equipment take?
Delivery usually takes 24–72 h when the item is available locally or at the supplier. Most equipment of this type is made to order, and the lead time is usually 1–4 weeks. Complex systems, such as portal monitors, germanium spectrometers or effluent monitors configured to order, may need more time, depending on the brand and the specifications. We confirm the exact lead time in the quotation we send once we know the configuration you want. For work with a fixed deadline, state the desired date from the start, so that we can confirm whether it is achievable or propose an equivalent item.
Is calibration needed for radiation measuring instruments?
Yes, the results of a radiation protection instrument can be used in the installation's records and in reporting to the supervisory authority only if the instrument is calibrated and periodically verified, in line with the applicable requirements. Calibration is carried out in an accredited laboratory, with reference fields, and is repeated at the interval set by the user's procedure. Between calibrations, routine functional checks are made. The calibration certificate, where one exists for the model concerned, can be requested at quotation. State this in the request for quotation so that it is taken into account from the start. The supervisory authority may ask for additional documents, and an accredited laboratory can also issue certificates for instruments you already have.
What technical documentation do I receive with the equipment?
The equipment comes with the standard technical documentation: the data sheet, the user manual and the installation instructions, to which are added, on request, the calibration certificate or the declaration of conformity available for the model concerned. For systems integrated into installations, for example fixed monitors or portal monitors, it helps us to receive your system diagrams in good time, so that we can check the interfaces and communication protocols before ordering. The documents are in the language available for the product, usually English. If a document is missing, tell us in good time, so that we can request it before delivery and not delay commissioning.
