بررسی میزان مواجهه شغلی با پرتوهای غیریونساز و اثربخشی وسایل حفاظت فردی در انواع جوشکاری قوس الکتریکی متداول

Introduction: Welding is considered to be one of the main sources of occupational exposure to non ionizing radiations. The present study was conducted to examine the rate of occupational exposure to non-ionizing radiation in common welding processes. Materials and Methods: In the present descriptive analytical study, occupational exposure to different types of non-ionizing radiations in...

Measurement and Computational Modeling of Radio-Frequency Electromagnetic Power Density Around GSM Base Transceiver Station Antennas

Evaluating the power densities emitted by GSM1800 and GSM900 BTS antennas isconducted via two methods. Measurements are carried out in half a square meter grids around twoantennas. CST Microwave STUDIO software is employed to estimate the power densities in order fordetailed antenna and tower modeling and simulation of power density. Finally, measurements obtainedfrom computational and experime...

طراحی و ارائه یک بسته نرم‌افزاری مبتنی بر روش Control Banding جهت ارزیابی ریسک مواجهه شغلی با نانومواد

Background and aims: The development of nanotechnology has result in the creation of new job opportunities and economic growth. But the lack of sufficient information about the toxicity and occupational exposure limits to nanomaterials on the toxicity and occupational exposure limits established nanomaterials always has created concerns. In this study design and providing of a simple software p...

Extrapolating from toxicity data to occupational exposure limits: some considerations.

This paper evaluates procedures relevant to extrapolating from toxicity data in man and animals to Occupational Exposure Limits. It examines effects at or around the "No Observed Adverse Effect Level' (NOAEL) and the magnitude of safety factors which can be applied in developing occupational exposure limits for non-stochastic effects. The relationship between incidence of stochastic effect and ...
