“…The dose rate data presented here describe only four (fi rst worker) and two days (second worker) of work, but they clearly show how much time each worker spent in the vicinity of a radiation source. This is a novel feature in describing occupational exposure, and it could fi nd application in special (nuclear, radwaste), additional (nuclear medicine), or even regular personal dosimetry in the future (7)(8)(9)(10). Together with the hazard index (H ex ) obtained for possible 222 Rn inhalation of air or dust particles, it is possible to estimate the total radiation exposure burden for occupationally exposed workers performing their duties in dosimetrically complex environments.…”

“…Kontinuirano mjerenje i snimanje primljenih vanjskih doza te kao novitet, brzine doze kao funkcije vremena, daju novu i jedinstvenu snimku profesionalnih doza i uzoraka primanja brzine doze na danome radnome mjestu. Rezultati mjerenja profesionalne doze za cijelo tijelo dobiveni uporabom AED-ova uspoređeni su s dozimetrijskim rezultatima [Hp (10)] dobivenim uporabom pasivnih dozimetara (fi lmskih i termoluminiscentnih dozimetara). Provedene su gamaspektrometrijske analize zraka, prašine i silikatnog pijeska te su dobiveni podaci iskorišteni za procjenu moguće unutarnje izloženosti radnika 220 Rn inhalacijom zraka ili ingestijom prašine i pijeska.…”

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 account natural and artifi cial (man-made) electromagnetic ionizing radiation (γ 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 study 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, which is a novelty, establish dose rates receiving pattern as a function of real time. Occupational whole body dosimetric results obtained with AED were compared with results obtained with passive dosimetry (fi lm badge and thermoluminiscence). Air, dust, and silicon sand samples were analysed by gamma-spectrometry to estimate internal exposure of the two workers to 222 Rn due to inhalation or ingestion of dust and sand in indoor air. In order to establish total occupational exposure, control radon measurement was performed in the immediate environment and the external Hazard index (H ex ) was calculated.

“…AED ALARA OD is based on Geiger-Mü ller (GM) tube (4) and has a built-in software which records the total number of counts over a predefined integration time. This enables calculation of time-dependent dose/dose rate (3) . Its small size (5) permits to perform measurements without disturbing the security-workers routine.…”

Security personnel who operate X-ray units for the control of hand luggage and personal items at airports are generally not under dosimetric surveillance. A significant increase in the number of inspected items per passenger, due to rigorous air traffic security measures, raises a question of extended exposure of these workers to scattered X-ray radiation. A new approach to investigating directions of breaches of scattered X-ray radiation in the area near to an X-ray cabinet system, which is based on using active electronic dosemeters is presented. Influence of the increase in the number of inspected items in time on the dose rate is described. Time-dependent dose rates have showed a very good correlation with passengers undergoing security control prior to boarding an airplane. Measurements confirmed that an increase in the dose rate, coinciding with rush hours, was caused by scattered radiation passing through incompletely closed lead curtains. It is found that the doses at the entrance to the inspection tunnel are 50 % higher than those at the exit, which is a consequence of inherent operational characteristics of X-ray cabinet systems.
