MEASUREMENT OF MAGNETIC FIELD EMITTED FROM LABEQUIPMENT AND ELECTRICAL APPLIANCES IN ETE LABS OFDAFFODIL INTERNATIONAL UNIVERSITY, BANGLADESH

Abstract

The aim of this survey is to investigate whether the Electromagnetic Fields (EMF) emitted fromvarious lab equipment and air conditioners and switch boards affect the students, faculties and
employees. There is a standard threshold value recommended by WHO for both electric and
magnetic fields. Electro-Magnetic Field also named Non Ionizing Radiation is emitted from high
power transmission lines, computer monitor/video display unit, radio waves of different
frequencies, telecommunication, satellite, radar etc. which causes health hazards to living systemand environment. There has not been much study performed in Bangladesh. The data were
collected from various Electronics and Telecommunication Engineering (ETE) department labs at
Daffodil International University in Dhaka, Bangladesh. Threshold values of Magnetic fields are
measured for various lab equipment, 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.
