Concerns about ionizing radiation during interventional cardiology have been increased in recent years as a result of rapid growth in interventional procedure volumes and the high radiation doses associated with some procedures. Noncancer radiation risks to cardiologists and medical staff in terms of radiation-induced cataracts and skin injuries for patients appear clear potential consequences ...

introduction: esophageal cancer is one of the most frequently occurring cancers in iran and having a  high  incidence  rate  among  other  countries.  radiotherapy  is  one  of  the  three  methods  (surgery,  radiotherapy and chemotherapy) for radical or palliative treatment of esophageal cancer. in this method  of treatment, the organs such as heart and spinal cord are regarded as organs at r...

introduction radiation exposures from diagnostic medical examinations are generally low and are almost always justified by the benefits of accurate diagnosis of possible disease conditions. therefore, entrance skin dose (esd), body organ dose (bod), and effective dose (ed) from adult patients undergoing routine thorax posterior-anterior (pa) and thorax right lateral (rlat) were estimated in uni...

background: changes in body composition may be used for monitoring progression/ regression of a disease. prompt γ-rays in vivo neutron activation analysis (ivnaa) has been widely used for the measurement of body composition in recent years. objective: in this paper, we tried to improve the safety of ivnaa operator. methods: the most important factor for reducing the operator receiving dose is t...

The manipulation of a wide variety of unsealed sources in nuclear medicine results in a significant risk of internal exposure of the workers. 131 I should be highlighted among the most frequently used radionuclides because of its large application for diagnosis and therapy of thyroid diseases. The increasing use of radionuclides for medical purposes creates a demand for feasible methodologies t...

background: to evaluate the prevalence of hepatitis c by antibody testing, hcv-rna detection by pcr and relative risk fac­tors of hcv infection among hd patients and staff members in markazi province/iran. the other purpose was to deter­mine genotypes of hcv in this population. methods: the study group consisted of 204 hd patients and 47 staff members from all 9 dialysis centers in markazi prov...

introduction: depression as a disorder is relatively common in all societies several factors are involved in depression development, that shift work is one of these factors. this study compared the frequency of depression in different shifts of nurses in hospitals of yazd university of medical sciences. materials & methods: this study is a descriptive analytical study. based on statistical meth...

The relationship between the reported ambient dose equivalent (H*(10)) and the individual dose rate recorded by medical staff in Fukushima City after the accident at the Fukushima Daiichi nuclear power plant was evaluated, following a 9.0-magnitude earthquake that struck the east coast of Japan. Personal dose equivalent (H(p)(10)) ranged from 0.08 to 1.63 µSv h(-1) and H*(10) ranged from 0.86 t...
