background: the aim of the study was to analyze the effective dose record of occupationally exposed radiation workers at bahawalpur institute of nuclear medicine and oncology department. materials and methods: annual effective doses of occupationally exposed workers were measured by film badge dosimetry by sending the dosimeters to radiation dosimetry laboratory (rdl), pakistan institute of nuc...

a lithium borate thermoluminescence dosimeter with 0.3 wt% of manganese impurityconcentration was prepared for high dose levels in the range of 1-30 kgy for gamma irradiation applications.the tld reader was used for read out purposes from ambient temperature to about 400°c with a heating rate of 6°c/sec. the pre- and post- irradiation anneal temperature was 300°c for 1.5 and 1 hours respectivel...

background: the aim of this study was to investigate clinical applications of mobile c-arms and consequent radiation risk,to increase medical attention on radiation protection, and to provide basic data for safe radiation use in the operating room. materials and methods: in this study, a total of 374 surgical operations, conducted using a portable fluoroscopic x-ray system from january to march...

introduction the purpose of this study was to estimate organ and effective doses in patients undergoing some common x-ray examinations in sabzevar, iran. the effective dose is one of the best parameters for describing the amount of radiation dose received by a patient undergoing any diagnostic x-ray examination. the public dose from x-ray examinations depends on various factors, and its contrib...

To assess the pharmacological safety of dipeptide mimetic 2nd loop BDNF (compound GTS-201) when co-administered with ethanol, its effect on alteration in motor activity induced by ethanol during acute and subchronic administration mice C57Bl/6 DBA/2 was studied. It found that GTS-201 at a dose 5.0 mg / kg, i.p., without affecting spontaneous per se, after preliminary prevented development sedat...

Specific goals The new radiological protection system for the environment increases the need to estimate radiation doses to non-human biota in their specific environment. Therefore, reliable and realistic dose models are needed in risk assessments of biota. Current dose models for biota (e.g. ERICA, 2007) have been developed mainly to be used as a screening tool for the assessor and little guid...

PURPOSE To evaluate the response time and safety profile of low-dose oral methotrexate pulsed therapy in idiopathic retinal periphlebitis (Eales' disease). METHODS A tertiary care center-based prospective interventional study, based on visual acuity grading, was undertaken. Twenty-one consecutive patients with idiopathic retinal periphlebitis were administered 12.5 mg methotrexate as a single...

Because of the adverse effects of ionizing radiation on fetuses, prior to radiotherapy of pregnant patients, fetal dose should be estimated. Fetal dose has been studied by several authors in different depths in phantoms with various abdomen thicknesses (ATs). In this study, the effect of maternal AT and depth in fetal dosimetry was investigated, using peripheral dose (PD) distribution evaluatio...
