Introduction: Microwaves are a part of the electromagnetic radiation spectrum that has high frequency and short wavelength. The purpose of this study is to determine electromagnetic radiation emitted from household and restaurant microwave ovens. Methods: The survey was carried out for 45 ovens used in households and restaurants. Electromagnetic radiations from different brands of microwave ov...
With the development of science and technology, microwave has been used in many fields such as industry, military, medicine and communication. People are living in a lapped and dynamic electromagnetic environment. Concerns about potential hazards of microwave are getting increasing attentions. The single biological effects of microwave were widely discussed which was considered harmful. Relevan...
Due to the complicated structure of microwave radiometric imaging system and the massive amount of data collection in one snapshot, it is difficult to achieve the high spatial resolution image by conventional microwave radiation imaging method based on the Nyquist sampling. In this paper, according to the priori information of the compressible multi-structural information of microwave radiation...
Introduction: Recent increase of endocrine disorders may be correlated to the increased exposure to electromagnetic fields from various instruments. Radiation leakage from microwave oven may be harmful for users. Ladies have the highest levels of contact with microwave ovens. This study was carried out to evaluate the effect of radiation leakage from microwave oven on body weight, cortisol a...
Background & Objective: The vast use of microwave ovens in today's modern life and possible exposure of users to radiation exited from the oven lead us to investigate the effect of this radiation on sex hormones. In the present study, the effect of microwave ovens radiation leakage on concentration of LH, FSH and testosterone hormones has been investigated. Materials & Methods: Thirteen immatur...
Abstract Background and Objectives: Incidents related to electromagnetic interference with medical devices have been reported over the past decades. It has also been indicated that the microwave radiation emitted from mobile phones interferes with the operation of medical devices therefore, this study aimed at testing the interference by GSM mobile phones with cell counters. Material and Method...
Background: High-frequency electromagnetic field (EMF) is generated by differentsources such as radar installations, radio and television transmitters, medical microwave diathermy device and domestic use of microwave ovens. Radiation leakage of microwave oven may be harmful for users. Kids who are residing near their mothers may expose to electromagnetic field. This study was carrie...
This study was conducted in an attempt to characterize some of the effects of sublethal microwave radiation on cells of Staphylococcus aureus. Cultures were exposed to microwave radiation for 10, 20, 30, and 40 s. The effects of a conventional heat treatment were also compared by placing flasks containing cultures in a boiling water bath for the amount of time required to reach temperatures equ...
With the rapid development of electronic technologies, anxiety regarding the potential health hazards induced by microwave radiation (MW) has been growing in recent years. The brain is one of the most sensitive target organs for microwave radiation, where mitochondrial injury occurs earlier and more severely than in other organs. Energy metabolism disorders do play an important role during the ...
The increasing use of wireless systems in educational and administrative environments has caused concern People working in these environments about the physical and psychological effects of the waves on health. This study was conducted to assess public exposure to microwave emissions intensity of the wireless system (Wireless) Qazvin University of Medical Sciences. In this cross-sectio...
