Sažetak
Radiation dosimetry in protection against ionising radiation involves research of all possible pathways through which natural or man-made radioactive materials can contaminate a habitat and actually harm its biota. It also takes into acount natural and artificial (man-made)electromagnetic ionising radiation (y and x radiation). This article presents a dosimetric study assessing exposure to man-made ionising radiation of local environment and total occupational exposure of two professional workers involved in characterisation, conditioning and securing of unused radioactive sealed sources. The purpose of the stady was to validate a new active electronic dosimeter (AED) of type ALARA OD and to develop a new monitoring method by tracing the external occupational exposure over real time. This method is used to continuously measure and record external radiation doses and, wich is a novelty, establish dose rates receiving pattern as afunction of real time. Occupational whole body dosimetric results obtaind with AED were compared with results obtained with passive dosimetry (film badge and thermoluminiscece). Air, dust and silicon sand samples were analysed by gamma-spectrometry to estimate internal exposure of the two workers to Rn-222 due to inhalation or ingestion of dust and sand in indoor air. In order to establish total occupational exposure, control radon measurement was performd in the immediate environment and the external Hazard index (Hex) was calculated.
