Background: The present study aimed to introduce a rapid transmission dosimetry through an electronic portal-imaging device (EPID) to achieve two-dimensional (2D) dose distribution for homogenous environments. Material and Methods: In this Phantom study, first, the EPID calibration curve and correction coefficients for field size were obtained from EPID and ionization chamber. Second, the...
objective: radiation effects induced in non-irradiated cells are termed radiation-induced bystander effects (ribe). the present study intends to examine the ribe response of qu-db bystander cells to first, second and third radiation fractions and compare their cumulative outcome with an equal, single acute dose. materials and methods: this experimental study irradiated three groups of target ce...
Manipulations of lethally-irradiated animals, such as for administration of pharmaceuticals, blood sampling, or other laboratory procedures, have the potential to induce stress effects that may negatively affect morbidity and mortality. To investigate this in a murine model of the hematopoietic acute radiation syndrome, 20 individual survival efficacy studies were grouped based on the severity ...
