Measurement of Magnetic Field from Electrical Appliances in EEE Classrooms of Southeast University Bangladesh

Abstract

The aim of this survey is to investigate whether the Electromagnetic Fields (EMF) emitted from various air conditioners and switch boards affect the students, faculties and employees. There is a standard threshold value recommended by World Health Organization (WHO) for both electric and magnetic fields. Electro-Magnetic Fields commonly known as Non Ionizing Radiation is emitted from high power transmission lines, computer monitor/video display unit, radio waves of different frequencies (extremely low frequency to microwaves), telecommunication, satellite, radar etc. which causes health hazards to living system and environment. There has not been much study performed in Bangladesh. The data were collected from various Electrical and Electronic department classrooms at Southeast University in Dhaka, Bangladesh. Both threshold values of Electric and Magnetic fields were measured for various air conditioners and switchboards. The maximum value of the magnetic field results showed that in many cases the magnetic field radiated from the different sources are greater than the threshold limit, which are the main point of our findings.

Empirical studies on the effect of electromagnetic radiation from multiple sources in Dhaka

“…Furthermore, a review was carried out on NIR, harmful consequences of NIR from mobile/cell phone and towers [47]. Inspections depicting the magnetic fields emitted by various sources like laboratory electronic and electrical appliances and instruments (pharmacy and textile laboratories, computer science and engineering (CSE), and electrical and electronic engineering (EEE) laboratories and classrooms) in Southeast University were performed [48]- [54]. Additionally electrical equipment and laboratory facilities in electronics and telecommunication engineering (ETE) and CSE laboratories of Daffodil International University (DIU), Bangladesh were investigated [55], [56].…”

Measurement and Assessment of Exposure to 50 Hz Magnetic Fields from Common Home Electrical Appliances

“…Haque et al [31]- [33]; and Quamruzzaman et al [34], [35] performed various works on measurement of magnetic fields emitted from electrical appliances, laboratory equipment, switchboards and air conditioners in various laboratories and classrooms of some universities in Bangladesh. They found that many of the emission in the classrooms and laboratories are beyond the threshold limit especially from the air conditioners.…”
