“…the increased dose rate the clinician's eyes receive despite wearing Pb glasses, as the angle of gaze moves to 45 • and 90 • from 0 • toward the scattering source. The gap between Pb glasses and the skin becomes wider as the angle of gaze increases, allowing more scattered x-rays to enter the eye [27]. The lens and frame of 0.75 mm Pb glasses are flat and straight; therefore, the gap between these glasses and face/eyes is wider than that between the face/eyes and 0.07 mm Pb glasses, which are curved to fit the face, resulting in less gas between the glasses and face/eyes.…”

Increased x-ray exposure to physicians’ eye lenses during radiology procedures is a significant concern. In this study, x-ray exposure to the eye was measured using an anthropomorphic head phantom, with and without radiation-protective devices, to examine the dose of x-ray radiation that physicians are exposed to during endoscopic retrograde cholangiopancreatography (ERCP). X-ray exposure of the eye was measured using novel dedicated direct eye lens dosimeters that could specifically measure H p(3) during the ERCP procedure. The spatial dose in the height direction of the physician was measured using an ionization chamber dosimeter. Eye dosimeters were attached inside and outside the lead (Pb) glasses attached to the head of the human phantom to demonstrate its protective effect. Irradiation from the system lasted for 30 min. When the overcouch x-ray tube system is used, the cumulative radiation dose over the 30 min x-ray fluoroscopy time, without the use of radiation-protective devices, to the left and right eyes was 3.7 and 1.5 mSv, respectively. This dose was estimated to be the dose to the lens per therapeutic ERCP examination. With radiation-protective glasses, the dose reduced to 1.8 and 1.0 mSv for the left and right eye, respectively. The results of our study indicated that radiation exposure to the eye was reduced by up to 80.0% using Pb glasses and by 96.8% using radiation-protective curtains. Our study indicates that a physician’s maximum radiation exposure to the eyes during an ERCP procedure may be above the level recommended by the International Commission on Radiological Protection when the physician does not use radiation-protective devices. The eyewear, which is larger and fitted more closely to the face, provided a better protection effect even with a low lead equivalence, demonstrating that the shape of eyewear is important for protective function.

“…W badaniach laboratoryjnych wykazano, że użycie takiej technologii w połączeniu ze szkłem ołowiowym umożliwia ok. 6-krotną redukcję dawki na soczewkę oka [31]. W tym samym badaniu stwierdzono także, że zależność kąta kierunku patrzenia od redukcji dawki otrzymanej na soczewkę oka wynosi 3,13-143,69% w stosunku do kierunku "na wprost" na źródło wiązki rozproszonej promieniowania RTG [31]. Co więcej, gdyby takie okulary były używane rutynowo, operator mógłby dzięki nim mieć podgląd na obrazy operowanego organu wykonane nie tylko aparatem do fluoroskopii, ale także np.…”

Odkrycie promieniowania jonizującego przyniosło wiele korzyści również w medycynie. Związane z nim ryzyko wywoływania chorób, takich jak nowotwory popromienne czy zaćma, skutkuje koniecznością monitorowania narażenia osób pracujących w ekspozycji na promieniowanie jonizujące za pomocą dozymetrii indywidualnej lub optymalizacji procedur medycznych. Istnieją 3 główne sposoby optymalizacji procedur medycznych-redukcja czasu, zwiększenie odległości oraz stosowanie osłon osobistych i stałych. Wraz z rozwojem nauki i techniki ewoluują sposoby zmniejszania dawki. Poza lepszą osłonnością wzrasta także ergonomia, jak w przypadku osłony Zero-Gravity i lekkich fartuchów bezołowiowych. Rośnie także świadomość konieczności stosowania osłon i prowadzenia zabiegu tak, aby zmniejszyć narażenie zarówno personelu, jak i pacjenta. Celem artykułu jest przedstawienie nowych metod ochrony przed promieniowaniem jonizującym w kontekście powyższych 3 pryncypiów ochrony radiologicznej. Med. Pr. 2021;72(1)
