[ 1 ] - Estimating the Radiation-Induced Cancer Risks in Pediatric Computed Tomography

Introduction One of the central questions in radiological protection is the magnitude of the risks from low doses of radiation, related to the justification and optimization of the diagnostic medical exposures. Therefore, the aim of this study was to estimate the cancer incidence and mortality risks in children of different ages, sizes, and ethnicities undergoing computed tomography examination...

[ 2 ] - A Novel Neutron Dosimeter

Background: Neutron contamination in our environment can cause harmful biological effects on human body. Therefore, many efforts have been made to construct a neutron dosimeter to estimate the received dose. Objective: To design a simple neutron dosimeter. Methods: The primary dosimeter had 3He as a spherical thermal neutron detector encircled by paraffin 10 cm in radius. Then, the paraffin sph...

[ 3 ] - Evaluation of polyurethane composite shields effect on reducing the risk of cataract induction at head CT scan

Head computed tomography is a common diagnostic examination, which may cause lenticular opacity and cataracts. Cataract induction is one of the non-stochastic effects of radiation, that happens at threshold dose of 0.5 Gy. Recent studies illustrate that only irradiation to the sensitive (germinative) zone of the lens is a prerequisite to cataract development. Recently, the dose values absorbed ...
