background and objectives: not reporting medication errors by the clinical staff prevent identification of type and frequency of these errors, and thereby developing effective strategies to alleviate the problem. most investigation of barriers to medication error reporting comes from public hospitals. this study aimed to explore the issue from a nurse’s perspective in private hospital. methods:...
Background: The most frequent imaging techniques used by NM departments are skeletal scintigraphy and bone scans. To assess the protective measures anticipated radiation hazards, it is crucial to evaluate patient's doses for NMC staff. Objectives: Current research intended annual effective of radiology department’s staff during scans their health hazards due radiation. Methods: study was execut...
Introduction: A hospital as a health care institution providing treatment services can be heavily influenced by sources of noise. Noise pollution has negative impacts on patient comfort and staff welfare. This study aimed to evaluate the relationship between noise annoyance and sensitivity with noise parameters (PNC, SIL) in the hospitals of Behbahan. Methods: This study...
Recently, attempts to develop new types of swallowing function analysis with 320-detector-row multislice CT (320-MDCT) have been reported. The present report addresses (1) patient exposure, (2) operator exposure, and (3) spatial dose distribution. For dose measurement, a human-body phantom in which 303 thermoluminescent dosimeter elements were inserted and a survey meter was used. The patient p...
the study aims to achieve research and testing of hypotheses survey techniques and questionnaires to collect information used. 61 questions in the questionnaire included 15 questions and 46 open questions according to research in the study population, girls and their mothers as the value of different children investment should be. mothers according to the research community benefits from havi...
Since new radiopharmaceuticals are used like [18F]-fluoro-3'-deoxy-3'-Lfluorothymidine and 18F fluoromethylcholine, also new dynamic techniques of imaging are used, measurements concerning the doses to medical staff are needed. The aim of this study was to measure the effective whole body dose of the personnel and compare them with the oldest. Estimation of equivalent dose for all members of th...
BACKGROUND Due to its use of ionising radiation, the field of nuclear medicine is a unique and significant part of medical diagnostics and patient treatment. The aim of this study was to assess the internal exposure of nuclear medicine employees to radioiodine 131I and technetium 99mTc as well as to assess the external exposure doses. MATERIAL AND METHODS The radioiodine 131I and technetium 9...
Background: Since 1996 the assessment of environmental gamma radiation dose in residential areas of Iranian towns and cities has been accomplished for 10 counties. As a practical method and based on the results of a pilot study, in order to attribute the final results to the whole residential area of a town five stations were selected for every town. The location of individual station wa...
Objective: The aim of this study is to evaluate the effect of tissue composition on dose distribution in electron beam radiotherapy.Methods: A Siemens Primus linear accelerator and a phantom were simulated using MCNPX Monte Carlo code. In a homogeneous cylindrical phantom, six types of soft tissue and three types of tissue-equivalent materials were investigated. The tissues included muscle (ske...
