introduction: colored compounds which often are toxic and carcinogen is one of the environmental pollutants. these pollutants should be removed prior than discharge to the environment. the aim of this study was the evaluation of maize tassel powder efficiency for the removal of reactive red 198 dye from synthetic textile wastewater. materials & methods: this experimental study was performed in ...

This study has developed a compact, low-cost, and real-time mobile monitoring (MM) device for estimating the PM2.5 inhaled dose. The MM consists of low-cost sensor, temperature humidity Wi-Fi module, microcontroller unit. system (carried on vehicle) been used to measure concentration, geolocation, meteorological factors during rush hour. To examine repeatability, new method was proposed calcula...

background: humans beings are continuously exposed to ionizing radiation from natural sources. the main contributors to natural radiation are high-energy cosmic radiation and radioactive nuclides that originates in the earth’s crust. exposure to high levels of radiation can cause serious health effects. in this study an attempt has been made to monitor the levels of environmental background rad...

The contribution of low-energy particles down to ~200 eV the dose deposited on very near surface materials subject space environment is investigated by means GEANT4 Monte Carlo simulations. dose, parts Global Radiation Earth ENvironment (GREEN) spectra (200 eV-40 keV for electrons, 200 eV-100 protons), compared with calculations performed AE8/AP8. Both geostationary earth orbit (GEO) and low (L...

Introduction: The purpose of this work was to study the ability of MRI normoxic polymer gel dosimetry for evaluating the dose distribution in HDR brachytherapy of esophagial cancer at Imam Reza brachytherapy center (Mashhad, Iran). Materials and Methods: Initially, 2liters of normoxic gel (MAGIC) was fabricated and then poured into 12 calibration test tubes and placed in a perspex walled phanto...
