title: [Measurement of personal dose equivalent of X and gamma radiation by ring dosimeter: results of intercomparison measurements].
abstract: BACKGROUND
  The aim of the study was to present the results of the interlaboratory comparisons for ring dosimeters and to confirm that the applied method is suitable for measuring the personal dose equivalent H(p)(0.07). In addition, calibration procedures used in dosimetric measurements in persons occupationally exposed to ionizing photon radiation X and gamma were presented.
  
  
  METHODS
  Ring dosimeters made of flexible plastics with the diameter of approximately 20 mm, equipped with two thermoluminescence (TL) detectors type MTS-N, were the subject of interlaboratory comparisons. Irradiated detectors were red out using a new manual TLD's reader (FIMEL, France). All TLD exposures were done for validation of TLD readers and were performed using the reference X-ray and gamma beams with the ISO rod phantom. The methodology of performed exposures corresponded with the methods applied by the European Radiation Dosimetry Group (EURADOS), the European organizer ofinterlaboratory comparisons.
  
  
  RESULTS
  The energy, dose and angular characteristics of the ring dosimeter allowed to elaborate the formula for estimating and verifying the personal dose equivalent H(p)(0.07). The test was performed to check and confirm the correctness of the estimated characteristics. The test results were satisfactory, and thus the readiness to implement TLD reader in the used method and to participate in interlaboratory comparisons was confirmed.
  
  
  CONCLUSIONS
  According to the requirements of the Polish Centre for Accreditation, the laboratory was participating in the interlaboratory comparison organized by EURADOS in terms of the personal dose equivalent H(p)(0.07). The result of the comparison was satisfactory, therefore the correctness of the testing procedure was confirmed.
