Accreditation

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.

Calibration of dosimetry apparatus

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:

  • Determination of the instrument's response in the field of the selected neutron source(s),
  • Checking the discrimination of gamma radiation in the detector,
  • Inspection of the directional response of the instrument.

Calibration of TLD albedo detectors on a phantom includes:

  • Exposure of the dosimeter to 1 neutron dose value

 

Instruments for measuring the dose power of gamma radiation in the gamma radiation field.

The calibrations we perform include:

  • Determination of the response of the instrument with respect to a standard radiation source of the selected isotope.

Polityka Jakości LPD

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:

  • systematically increasing the competence of LPD personnel through participation in external and internal training,
  • development of the range of services offered,
  • continuous upgrading and increasing the reliability of measuring and calibration apparatus,
  • Ensuring personnel and technical resources to achieve the above objectives.
  • ensuring the confidentiality of information produced or obtained in the course of laboratory activities to customers, except as required by law or contractual provisions
  • impartially organize and manage laboratory activities ;
  • taking into account risks and opportunities in improving the management system

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.
