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.

Liquid and Gaseous Effluent Monitoring



Continuous measurement of volumetric activity of radioactive iodine in the air during normal operation and also during emergency or post-emergency state of a nuclear power plant


Aerosol Sampler

BOA-80 Aerosol Sampler

A device designed for balance sampling of aerosols from the air to determine its contamination 


Continuous Particulate Detector

CPD-14 Continuous Particulate Detector

CPD-14 measures the activity of alpha and beta active aerosols from the air

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

Poptat u výrobce

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.

Personnel and Tools Contamination

Hand Contamination Monitor

HM-4 Hand Contamination Monitor

A device intended for the signalisation of hand contamination by alpha, beta, or gamma radionuclides


Floor Contamination Monitor

FloorScan Floor Contamination Monitor

A device intended for signalisation of floor surface contamination

Portable and Laboratory Equipment

We have developed a number of user-friendly portable devices with regard to our customers´ needs.

Our portable and laboratory equipment is designed  to detect ionising radiation, measure contamination and dose rate or neutron flux.

Portable Activity Meters

PAM-525 Portable Activity Meters

Handheld portable devices designed to measure the surface activity of alpha, beta, and gamma radionuclides. It allows fast measurement of large areas.


Display Unit

RadCount-2S Display Unit

A multi-purpose display unit. When connected to an external detector, it serves as a gamma or neutron dose equivalent monitor.

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.
