[en] Burden of health care personnel working on linear accelerators. New examination and treatment methods enable to reduce the number of health care personnel even in the case of increased numbers of examined patients. However, still open is the question of determining the effective dose delivered to health care personnel. The employment of several methods of evaluation of received dose at one workplace makes it possible to compare the accuracy and reliability of the respective types of measuring devices, as well as to point out the pitfalls of their use.At the St. Elizabeth Cancer Institute we compared the results of measurements of TL dosimeters, and OSL dosimeters at workplaces with linear accelerators.

[en] State Office for Nuclear Safety executes state administration and performs inspections at peaceful use of nuclear energy and ionizing radiation in the field of radiation protection and nuclear safety. Inspections on radiation protection at nuclear power plants are secured by inspectors of the Department of Radiation Protection in Fuel Cycle, who work at the Regional centre Brno and Ceske Budejovice.

[en] The project under the title OPPA CZ.2.17/3.1.00/36038 'Modernization of Practical Education of CTU FNSPE Nuclear Engineering students' provides an opportunity to innovate existing exercises and set up new experimental exercises. The Department of Dosimetry and Application of Ionising Radiation has prepared or innovated the exercises which are described. (authors)

[en] Following the first part, in this paper on a real case of escaped radioactive matter in gaseous or aerosol form the significance of known the air exchange rate for a prediction of wasted inhalation doses to population will be illustrated. (authors)

[en] The lecture will introduce new functions and graphic design WebSOD - web interface Personal dosimetry Service VF. a.s. which will be updated in November 2014. The new interface will have a new graphic design, intuitive control system and will be providing a range of new functions: - Personal doses - display of personal doses from personal, extremity and neutron dosimeters including graphs, annual and electronic listings of doses; - Collective doses - display of group doses for selected periods of time; Reference levels - setting and display of three reference levels; - Evidence - enables administration of monitored individuals - beginning, ending of monitoring, or editing the data of monitored persons and centers.

[en] The paper discusses the current state of quantification of exposure and points out some problems and inconsistencies regarding the definitions of some quantities used in radiation protection. Attention is paid in particular to the interpretation of the effective dose, equivalent dose, organ dose and other quantities needed for monitoring workers and workplaces. Special consideration is given to some contradictions related to the skin exposure of workers in nuclear medicine, where some ambiguous approaches are sometime applied to control and limit personal exposure.

[en] Within the research project MOSTAR was for needs of modern radiation monitoring vehicle proposed and realized inner transformation of ordinary car. Poster presents car-borne system with a basic spectrometry identification, determination of heading to source using by two detectors located on lateral sides of vehicle, dose rate logging and their mapping. Part of a monitoring vehicle is a semiconductor spectrometric trace for quick qualitative and quantitative evaluation of samples of living environment and other detectors for field measurement.

[en] Within the Czech Ministry of Interior Project 'Research of advanced methods for detection, assessment and consequent control of radioactive contamination' field tests have been performed aimed at study atmospheric dispersion of radioactive substances dispersed by a small-size explosion. The presentation will be aimed at basic information on experimental configuration and conditions, as well selected results. (authors)

[en] In the paper, the ICRP and IAEA criteria for adoption of protective measures in emergency exposure situations are discussed. Using the ESTE Analyst code and presuming that IAEA criteria are fulfilled, distances for adoption of protective measures are assessed depending on the quantity of release. (authors)

[en] Since 2002, regular postal audit in dental radiography organized by NRPI Prague belongs to basic radiography QA/QC tools in the Czech Republic. The measured parameters are incident air kerma, field size, and exposure reproducibility. The overall quality of the dental radiograph is also assessed. Ten-year summary of the audit results is presented here. (authors)
