EXPOSURE DOSE DURING INTERVENTION OF NEUR ORADIOLOGY OF THE HEAD IN CHILDREN

Purpose: We reviewed different dosimetric results in three children in vestigated for haemangioma, arteriovenous malformation, and angioma of the head in comparison to global results in 71 adults. Method: The de tailed patient dosimetry was performed using thermoluminescence dosime try (TLD), area-dose exposure meter (ADE), and Alderson phantom. Resul ts: The patient doses of relevant organs ranged in the milli-Grays (mG y) level. The irradiation-induced risk is on a per mil level in respec t of ICRP-60. The risk of cerebral angiographic procedures, radiothera py, or surgical interventions is on a per cent level, The organ doses for staff are on a micro-Gray (mu Gy) scale and are higher in examinat ion of children than of adults. A statistical limit of examinations de pends on yearly or life-time dose limits with regard to the ,,Rontgenv erordnung'' (Germany).
