Individual Monitoring and Categorization of Exposed Workers

Based on its authorisation, EKOTEH has been providing personal dosimetry services to its clients (customers) since 1995. In accordance with applicable regulations, clients are required to ensure that their exposed workers undergo personal exposure monitoring during work.

Personal dosimetry for 4,000 individuals is carried out using Panasonic UD-802 and UD-803 (Li₂B₄O₇:Cu) thermoluminescent dosimeters (TLDs) and the Panasonic UD-7900 reader, following method PO 7.2.1-01 , for which EKOTEH is accredited by the Croatian Accreditation Agency (HAA).

All EKOTEH’s contractual clients register in the dosimetry system by submitting a completed form available on the EKOTEH web page. Other required forms are available on the web site of the Civil Protection Directorate .

Categorization of Exposed Workers

The categorization of exposed workers is carried out based on the following:

  • A statement by the radiation protection officer regarding the types of ionizing radiation sources, the estimated workload, and the duties performed by the exposed worker;
  • An assessment of the external exposure of the exposed worker, based on the results of individual measurements obtained using passive personal dosimeters Hp(10), evaluation of the results of radiological monitoring of the workplace H*(10)/t, and potential exposure, taking into account exceptional circumstances during the handling of ionizing radiation sources.

The request for categorization is submitted via a designated form.
