Radiation Protection Measurements Laboratory is involved in the assessment of the impact of the Świerk nuclear centre on the surroundings and monitoring of exposure to ionising radiation of NCBJ personnel.
The LPD provides services to external entities in the field of calibration of dosimetry apparatus, dosimetry measurements and training and expertise in the field of dosimetry and radiological protection.
Operating within the structures of LPD, the Testing Laboratory No. AB567 (Contamination Measurement Section) and the Calibration Laboratory No. AP070 (Dosimetric Apparatus Calibration Section) have been accredited for more than 14 years by the Polish Centre for Accreditation in Warsaw (a signatory to multilateral agreements within the framework of international organisations operating in the field of accreditation, i.e.: EA MLA, IAF MLA and ILAC MRA).
The laboratories perform tests and calibrations in a reliable, credible and impartial manner, in accordance with the declared Quality Policy.
Since 2017, in order to meet customer expectations, our Testing Laboratory has a flexible accreditation scope for gamma-ray spectrometric measurements of biological and environmental samples.
The current accreditation scopes of the AB567 and AP070 Laboratories are available on the website of the Polish Accreditation Centre.
scope of accredited activities:
scope of accredited activities:
Experience gained over a long period of activity, modern apparatus of world standard, introduction of new measurement techniques and competent, highly qualified staff, allow us to achieve optimum effects of work and place the Radiation Protection Measurements Laboratory in the forefront of laboratories in the country and abroad.
Neutron instruments, both passive (e.g., TLD dosimeters) and active (radiometers and neutron probes), are calibrated in standard dose equivalent fields and dose equivalent power. Depending on the customer's needs, 252Cf, 241Am-Be or 239Pu-Be sources exposed in open space are used for calibration.
The calibrations we perform include:
Calibration of TLD albedo detectors on a phantom includes:
Instruments for measuring the dose power of gamma radiation in the gamma radiation field.

Activity measurements of environmental samples
Dosimetry Expertise
Dosimetric measurements performed with operational instruments outside the LPD
Training in the field of ionizing radiation dosimetry, including determination of concentration and activity of α, β and γ radiation in materials of various types:
The final scope of the training is each time agreed with the client.
Training is carried out at the premises of the Radiation Protection Measurements Laboratory using the technical potential of accredited testing and calibration laboratories with standard gamma and neutron radiation fields and radioactive reference materials.
Assessment of conditions of exposure to ionizing radiation during work with artificial and natural sources of ionizing radiation. Support during the preparation of documentation for notification in the field of radiological protection (in accordance with the requirements of the Atomic Law).
Inspection and maintenance of apparatus
Inspection of damaged instrumentation includes:
minor repairs (replacement of batteries)
Assessment of the technical condition of the instrument (required provision of technical documentation)
The goal of the NCBJ Radiation Protection Measurements Laboratory is to provide high quality services (tests, calibrations) through the implementation, maintenance and improvement of a management system in accordance with the requirements of PN-EN ISO/IEC 17025:2018-02. The accreditation certificates obtained by the Laboratory confirm its competence.
The pursuit of this goal is achieved (among other things) through:
LPD personnel are familiar with and apply in their work the Quality Policy and the documentation of the management system and regularly participate in its continuous improvement. The integrity of the management system and consistency in the implementation of laboratory activities is maintained when planning and implementing changes.
The implementation of the Quality Policy and the operation of the management system are systematically supervised through internal audits and management reviews.
The Director of NCBJ undertakes to provide the necessary resources for the operation of the LPD management system. Responsible for compliance with the management system in LPD is its Head.
