More than 1000 radiation workers are engaged in about 70 private industrial radiography companies (IRCs) using 312 mobile gamma radiography devices (GRDs) in Iran. These companies mainly carry out radiography in open areas using 192Ir radioactive sources, ranging from 0.07 to 3 TBq (2-80 Ci). The radiation accidents that occurred in these companies led to acute radiation syndrome in 13 workers ...

The authors present their experiences with 185 computed tomography (CT)-guided needle placement procedures in 146 consecutive patients. There was 100% accuracy in first-pass entry into the lesion using a needle guide; 100% success in drainage of intracranial abscesses; 100% success in palliative decompression of intracranial cystic lesions including tumor cysts; and 97% accuracy in histologic d...

Purpose Biological and/or physical assays for retrospective dosimetry are valuable tools to recover the exposure situation and aid medical decision making. To further validate improve such biological assays, in 2019, EURADOS Working Group 10 RENEB performed a field exercise Lund, Sweden, simulate various real-life scenarios.Materials methods For dicentric chromosome assay (DCA), blood tubes wer...

The malevolent dispersion of radioactive material, with the aim contaminating people and environment, is considered a credible terroristic threat. This article analyzes hypothetical Dirty Bomb detonation in an urban area, estimating radiological consequences to involved population first responders. material simulated using HOTSPOT code, considering explosion devices containing (alternatively) 6...
