Uma exposição acidental aos raios X de um difratômetro

Abstract

The patients's clinical pictures, characterized by an erythema preceding the skin manifestations, their aspect and the occupational histories, made the diagnosis of a radiation accident possible before its dosimetric identification. Doses evaluations using thermoluminescence dosimeters and ionizing chambers correlated well with the clinical estimations. The immediate cause of the accident was poor maintenance of the device that caused its back window to be permanently open, but lack of adequate information on the biological effects of ionizing radiation and on the correct operational procedures were contributory facts. The description of this accident is relevant in virtue of the misconception that such equipment have "virtually no occupational risk". The patients's medical evolutions have had a favorable course, specially because the low energy of the X-ray and its low penetrating capacity. This accident highlights the need for the adequate training of workers on the handling of radiation devices.

Evaluation and Statistical Analysis of the Use of Individual Dosimeter by Radiology Professionals in the Municipality of Goiania by Decree SVS/MS Nº 453/1998

“…In Brazil, it is essential to train the occupational health team in every industry where radioactive sources, open or sealed, are handled, including those in health facilities [11,13], since the journal control is deficient regarding the use Rogério Ferreira da Costa, Sara Coelho Avelino, Nayton Bruno Furtado Pessoa, Alana Galvão Costa Guimarães ____________________________________________________________________________ of radiation sources and many companies do not promote training and lectures on radiation protection and hygiene to their employees, not simply to encumber costs [14]. Recent work shows that professionals who have received training and lectures on radiation protection have obtained more correct answers to questions about the radiation protection of patients in collective environments [14].…”

“…Importantly, the companies of medical and dental diagnostic radiology should put into practice every day what is established at degree SVS/MS N o 453/1998, thus providing a higher quality service and security to the user [11,13]. And the continuing education of professionals and the implementation of procedures aimed at reducing doses are actions that result in adequate control of radiation exposure [15].…”
