Neutron detector - max. 600°, 20 bar

The fission chambers from PHOTONIS are used for in core and it can be operated at 6000c temperature and at external pressure of about 20 bar. The requirements of detection and the type of reactors used would determine the use of these chambers. For reactor monitoring these components are of prime importance. To control immediate, start up and power ranges, burn up of fuel monitoring in the reactor, or in high flux for the thermal neutrons detection these chambers can be used. These detectors are neutrons that are gas filled and are designed so that it can be operated in three different modes. For count of pulses on individual detector or analyzing of pulse mode it is used. To analyze any type of direct current fluctuation that can found in the detector the Campbell or fluctuation mode is used. Another mode which is current mode will be used when there requires a measurement of direct current mean in detector. Appropriate gas would be filled in fission chambers for fat response or for high temperature and they are extremely resistant towards radiation. As per the requirement and type of fission HN connector or a BNC connected would be used.

Radiation detection gate

Product Overview
Thanks to our long experience gained during production of radiation portal monitors based on Russian and US license, we have designed a state-of-the-art product that meets international standards.

Our RPM system has been developed by engineers from our R&D department in cooperation with the Polish National Center for Nuclear Research and scientists from Zielona Gora University.

Radiation Portal Monitor SMP system has been awarded the famous Teraz Polska (Poland Now) award in the category of Best Product for 2010. The SMP system follows recommendations of International Atomic Energy Agency from Vienna.

International distribution

After delivering few hundred radiation portal monitors to both national and commercial customers in Central Europe, our company has become a leader in the field of radiation detection.
We are currently looking for international distributors willing to join this profitable industry. We can give our partners a full and comprehensive support that begins from help in choosing the right equipment, training and after sales technical support.

Radiation detection gate / for vehicles - DF-6501

The system, with a high sensitivity and a low false alarm rate, can further screen out radioactive material that is mixed with other materials. The whole system is easy to operatewith a small on-site maintenance workload, is has long-term stability under harsh working environments.

Operating principle:

Radioactive elements in the decay process often produce a γ-ray.In case a person accesses the radiation monitoring system, it contains no radioactive material. The natural background radiation intensity received from the detector will fluctuate within a fixed range. Conversely, when the vehicle contains radioactive substances, γ-ray intensity exceeds the normal fluctuation range. A portal radiation monitoring system determines whether vehicle contains radioactive material by monitoring the changes in γ-ray intensity.
