We supply advanced radiation monitoring systems for research reactors, that reliably detect ionising radiation and protect the safety of people, environment and technologies.

Our experience comes from practice.

As one of the few manufacturers and suppliers of radiation monitoring systems, we have direct experience of service and maintenance directly at research reactors.

We follow technological and global trends and integrate them into our devices.

Dismatling and Decommissioning

We have a number of highly qualified employees, who are able to design and implement a complete disposal of workplaces where ionising radiation sources were used, or that were contaminated.

VF is also a producer of devices and equipment for measuring and characterisation of waste contaminated by radioactive substances. With our technology, customers can carry out the disposal of radioactive waste and free release.

The measurement of gaseous effluents from research centre plants makes up a significant part of overall radiation monitoring and control.

For the purposes of gaseous effluents monitoring, we have a number of products for sampling, online and post-accident measurement.

System installation and commissioning are an integral part of our delivery.

Calibration Laboratories

Ionising radiation measuring instruments are, according to legal or local requirements, subject to periodical calibration and verification in metrological laboratories.

To fulfil the metrological requirements placed on measuring instruments, we have developed a reliable calibration system.

The calibration system includes

  • An irradiator
  • A calibration bench
  • Data and control software

To prevent contamination spreading outside of a controlled area or other areas in research reactor facilities, personnel and tools contamination monitors are placed at the exits of these areas.

We have developed contamination monitors for the whole body, hands and feet, floors, clothing, as well as several types and sizes of tools contamination monitors. Their functionality is verified by many installations worldwide.

We are able to adapt our standard monitor types to specific customer needs and requirements.

Safe handling and disposal of radiation sources is one of our integral activities. We supply, test and replace sealed radionuclide sources.

We hold all necessary permits from regulatory authorities.

We operate our own hot cell and have a number of our own certified storage and transport containers for sealed radiation sources.

We also provide other services associated with radionuclide sources reloading in various types of irradiators, contamination monitor calibration with planar standards, etc.
