[Evaluation of absorbed dose-distribution in the X-ray or gamma-irradiator for blood products].
Irradiation of blood products abrogates the proliferation of lymphocytes present in cellular component, which is currently the only accepted methodology to prevent transfusion-associated graft versus host disease (TA-GVHD). A range of irradiation dose levels between 15 Gy and 50 Gy is being used, but the majority of facilities are employing 15 Gy. It should, however, be recognized that the deli...
متن کاملEvaluation of X-ray absorbed dose in thyroid during CXR imaging of the chest by Monte Carlo simulation (DOSXYZnrc)
Abstract: Introduction: Chest radiography is one of the most common X-ray imaging procedures performed worldwide. During this process, in addition to the chest, other tissues, including the thyroid, are also exposed to radiation. Due to the fact that one of the most important risk factors for thyroid cancer is ionizing radiation, measuring the absorption of X- rays in the thyroid is of spec...
متن کاملThe Effects on Absorbed Dose Distribution in Intraoral X-ray Imaging When Using Tube
Objectives: Efforts are made in radiographic examinations to obtain the best image quality with the lowest possible absorbed dose to the patient. In dental radiography, the absorbed dose to patients is very low, but exposures are relatively frequent. It has been suggested that frequent low-dose exposures can pose a risk for development of future cancer. It has previously been reported that ther...
متن کاملParameters affecting the X-ray dose absorbed by macromolecular crystals.
The lifetime of a macromolecular crystal in an X-ray beam is assumed to be limited by the absorbed dose. This dose, expressed in Gray (Gy = J kg(-1)), is a function of a number of parameters: the absorption coefficients of the constituent atoms of the crystal, the number of molecules per asymmetric unit, the beam energy, flux, size and profile, the crystal size, and the total irradiation time. ...
