Objectives
The wider objective of project B3.01/06 "Transfer of European Regulatory Methodology and Practices to the Nuclear Safety Authorities of Belarus - Regulatory Assistance and Technical Support in the Field of Radiation Protection and Emergency Preparedness (BE/RA/05)" is to continue the support and strengthening of the national nuclear safety and radiation protection regulatory system in Belarus.

The Project Specifications consist of the following three lots:

• Lot 1:      Calibration bench for gamma radiation dosimeters: infrastructure to allow verification, calibration, graduation and metrological testing of dosimetric instruments in a collimated beam of gamma radiation with differing intensity in dependence on source term and distance to source. Including radioactive sources for calibration of gamma radiation dosimeters. Radioactive sources (Cs-137) with the total activity up to 2,41∙1013 Bq (651 Ci). (Contract 214-303)
• Lot 2:      Radiation measurement techniques and devices: radiation measurement devices for qualitative and quantitative detection of alpha-, beta-, gamma- and neutron radiation. Device for identification, localisation and analysis of radia­tion sources. Dosimetric devices for dose assessment. (Contract 214-310)
• Lot 3:      Container-type decontamination unit: transportable decontamination unit with pre-decontamination in tent structure and final decontamination in different sections, housed in a standard 20 feet container (Contract 132-896).

Project Results

For Lot 1, this contract, the following equipment was delivered to RIFSE, the Research Institute for Fire Safety and Emergencies of the Ministry for Emergency Situations, in Svetlaya Roscha, Belarus:

• A Remote controlled irradiator with automatic movement of a selected source to exposure position and back, including an irradiator container with basis, shielding and collimator, timer unit and shutter, source holder, source changer, lifting crane with chain block.
• A Remote controlled 2-dimensional calibration bench structure for holding various instruments, including a mobile platform, monitors for the setup of dosimeters in the testing room and the observation from the control room and a laser alignment target.
• Radioactive calibration sources (Cs-137) with the total activity up to 54 TBq.

The equipment was delivered and installed successfully.
