Abstract

This research aims to explore if the Electromagnetic Fields (EMF) released by numerous domestic appliances affects the people. There is a typical threshold value for electric and magnetic fields endorsed by the World Health Organization (WHO). Electro-Magnetic Fields can instigate health risks to a living organism. There has been no such study performed in Bangladesh on domestic appliances. The data were collected from various home appliances in different locations in Dhaka, Bangladesh: Baridhara, Shyamoli, Mirpur, and Shakher tek. Both threshold values of electric and magnetic fields, as well as magnetic field values, were measured for several electrical and electronic appliances. Results obtained from magnetic field maximum values revealed that in numerous instances the magnetic field released from the various devices had exceeded the threshold limit.

ABSTRACT
This research aims to explore if the electromagnetic fields (EMF) released by numerous domestic appliances
affects the people. There is a typical threshold value for electric and magnetic fields endorsed by the World Health
Organization (WHO). Electro-Magnetic Fields can instigate health risks to a living organism. There has been no such study
performed in Bangladesh on domestic appliances. The data were collected from various home appliances in different
locations in Dhaka, Bangladesh: Baridhara, Shyamoli, Mirpur, and Shakher tek. Both threshold values of electric and
magnetic fields, as well as magnetic field values, were measured for several electrical and electronic appliances. Results
obtained from magnetic field maximum values revealed that in numerous instances the magnetic field relea sed from the
various devices had exceeded the threshold limit.
Keywords: EMF, WHO, NIR, EF, MF.
INTRODUCTION
Ionizing radiation is the radiation of adequately
high energy to instigate ionization in the medium. It can
comprise a stream of highenergy particle (e.g., electron,
protons, alpha particles) or high-frequency
electromagnetic emission (ultraviolet, X-rays, gamma-
rays). Radiation which does not produce any ionization of
the passing medium is non-ionizing radiation (NIR).
Radiowave, microwave, infrared, visible light, ultraviolet
are examples of NIR. Their energy is relatively low, only
triggering molecules to vibrate and stimulates heating
effects.
Human data from epidemiological studies,
including reported effects on cancer promotion, congenital
malformations, reproductive performance, and general
health, though somewhat suggestive to adverse health
effects, are not conclusive. Fields at radio frequencies
from 300 kHz to 300 GHz are measured in electric field
strength (V/m) and magnetic field strength (A/m). At
frequencies higher than 300MHz, power density (W/m2) is
usually used in hazard evaluation. Except for field far
from sources, both the electric field (EF) and the magnetic
field (MF) may have to be measured for a complete
specification. There is an unsubstantial report on the
effects of RF radiation on man and limited data on
reactions of animal unprotected to frequencies higher than
10 GHz and lower than 10 MHz; most animal research has
been carried out at frequencies near 3 GHz. People who
are working in the power sub-stations, radio and T.V.
transmitters should be cautious to protect their eyes and
should always maintain safeguarded space from the
transformers and panels, especially from the modulation
panel (Minimum 3 feet/ 90 cm). Since the magnetic field
is more detrimental than the electric field, there must be a
threshold both in the occupational and residential levels
between 0.2 to 0.3 µ T or 2.5 mG. (This value is
internationally documented as a standard limit in many
countries). Also, for the electric field, this value is 25V/m.
Nevertheless, for the person working at very high
frequency transmitting stations, safely protections, e.g.,
wearing of secured goggles, screened helmets and unique
clothing should be done. The length of exposure should be
kept minimum possible. The intensity of radiation in the
body should not surpass the recommended maximum limit
(10 mW/cm2, 195V/m in the U.S.A. and 0.1 mW/cm2, 20
V/m in CIS).
Nancy Wertheimer was the first scientist to
identify the connection linking magnetic fields and
childhood leukemia [1]. It is stated that high power
transmission lines [2-3], computer monitor, radio waves of
various frequencies in telecommunication, radar, satellite,
etc. also instigate damage to living organisms [4-5],
particularly in humans. It is known that high power
transmission lines cause human health risks. Also, there
are confirmations that the reason for suicide and clinical
depression are linked with the radiation from the power
lines [6-7]. A substantial fraction of miscarriage is
documented amongst women using electric blankets,
electric waterbeds and computer monitor. There are
instances that occupational hazards, e.g., Acute Myeloid
Leukemia (AML) may occur amongst the individuals
employed in the area of telecommunication. Also, it is
found that suppression of T- lymphocyte cell, cancerous
thyroid tumor, etc. may arise amongst the publics
unprotected to NIR. Small animals are informed to be very
sensitive to EMF. It is observed that animals, e.g., rats
build their (living offspring) holes away from the high
electric field and bees shield their hives in the chronic
presence of NIR/EMF. As a result, research communities
in developed countries have been conscious of the
consequences of NIR [8]. Their findings have given some
fantastic outcomes linking low-level alternating EMF with
grave health risks. It is alleged that the reason for Sudden
Infant Death Syndrome (SIDS) may have some link to
EMF. Also, there is proof that biological effect like
sensitive lymphocytes, disrupting DNA, immune
deficiency, the cellular breakdown is being influenced by
NIR.
There are some biological effects due to EMF
where these fields are higher than the naturally arising

electric and magnetic fields ~10-4 V/m and ~10-13 T
respectively [9]. EMFs could influence the creation of
agents (e.g., free radicals), which themselves can interact
with DNA or other agents that trigger chromosomal
damage, initiating translocation by prompting DNA breaks
or by the creation of abnormal DNA structures. Strains of
Salmonella uncovered to 15 or 30 mT magnetic fields at
0.3 Hz, 1-10 μT sinusoidal magnetic fields at 50 Hz
applied in 2 μs pulses or to a various range of radio
frequency and microwave fields exhibited no increase in
mutational frequency [10]. Fields (0.2 mT) at 60 Hz have
been informed to be mutagenic in Salmonella, causing a
14% increase in azide-induced mutations after 48 h
exposure [11]. Human lymphocytes uncovered to
sinusoidal 50 Hz, 60 Hz, or pulsed EMFs did not show
noticeable chromosomal variations or inhibition of DNA
repair mechanisms [10], [12-17]. Primary human
lymphocytes have been stated to display amplified
micronuclei formation when open to 75 or 150 μT fields at
32 Hz, but only when a parallel 42 μT d.c. field was
applied alongside to create the cyclotron and paramagnetic
resonance state for calcium [18], it increases in
chromosome defects in human amniotic cells unprotected
to an incessant or recurrent 30 μT sinusoidal field at 50 Hz
[19]. Uncovered to ionizing radiation, trailed by 60 Hz
magnetic fields as high as 1.4 mT, boosted the frequency
of near-tetraploid chromosome complements in human
peripheral blood lymphocytes [20], a result not observed
only with ionizing radiation. Adverse effects have been
seen in whole-animal reports: to escalate the frequency of
dominant lethal mutations in male mice was unsuccessful
with 50 Hz electric fields (20 kVm1), and 60 Hz fields of
as much as 50 kVm1 with magnetic fields as high as 1 mT
did not affect the frequency of sister chromatid swap in
mouse bone marrow [21-22]. Therefore, there are some
reports of positive EMF effects.
Some research has been accomplished in this
aspect. Epidemiological survey of public working in EMF
field unprotected from high frequency have been explored
[23]. Also, an epidemiological study was done on EMF
produced by photocopy machines in Dhaka [24]. A survey
was done on EMF by Laboratory appliances in Southeast
University laboratories in Bangladesh [25]. A case study
was done on EMF closeness to high voltage transmission
line [26]. A review was performed on NIR and its harmful
effects (mobile/cell and towers) [27]. An epidemiological
study was done on the Cathode Ray Tube (CRT) monitors
in Dhaka [28]. An investigation was performed in finding
the magnetic field emitted from various Lab equipment in
Textile Labs at Southeast University [29]. EMF was also
measured on Pharmacy Lab appliances in Southeast
University [30]. Magnetic Field measured from Electrical
equipment in Southeast University Bangladesh EEE
classrooms were performed [31]. The magnetic field from
electrical equipment in CSE laboratories and classrooms
of Southeast University, Bangladesh were done [32]. The
magnetic field from the lab and electrical appliances in
ETE laboratories in a private University in Bangladesh
were also measured [33]. EMF from cell phones used by
Southeast University students in Dhaka, Bangladesh was
also examined [34]. EMF produced from switchboards,
and air conditioners of another private University at Dhaka
in electrical and electronic engineering labs were also
computed [35]. An epidemiological survey has also been
performed on EMF produced by cell phones in Dhaka
[36].
There have not been many articles available on
EMF on domestic electrical appliances. The home
dwellers are being exposed to these appliances 12-24
hours per day. The objective of this effort is to save the
population who would be near to these and operating on
this equipment shortly from the destructive effects of
EMF.
METHODS
A Magnetic Science International MF meter
(Serial 624335) was used for computing the magnetic
fields for the lab equipment. A Coghill Field Mouse for
Biohazard Awareness was utilized for measuring the
threshold values for both magnetic and electric fields
around the equipment. Dr. Roger Coghill (UK) was the
designer of this equipment. The students completed the
tables for measuring the equipment. The data were
procured to cover all around the equipment.
RESULTS
All the readings were taken from numerous
domestic appliances from various locations in Dhaka city
Bangladesh. In Table-1, experimental data were collected
from multiple sites in Dhaka for micro-oven, water-heater
and table lamps.
Data were taken for five microwave ovens, five
water heaters, and 5 table lamps. The EF threshold
distance in front of the micro-ovens ranged between 38
and 65 cm, threshold distance at 45°angle from the frontal
surface ranged from 11 to 25 cm, Threshold distance at the
back of the instrument ranged from 26 to 48 cm, and
threshold distance at the top of the device ranged from 14
to 21 cm. The MF threshold distance in front of the micro-
ovens ranged between 17 and 34 cm, threshold distance at
45°angle from the frontal surface ranged from 4 to 12 cm,
threshold distance at the back of the instrument ranged
from 7 to 21 cm, while threshold distance at the top of the
device ranged from 8 to 17 cm. The EF threshold distance
in front of the water heaters ranged between 42 and 60 cm,
threshold distance at 45° angle from the frontal surface
ranged from 41 to 58 cm, threshold distance at the back of
the instrument ranged from 42 to 58 cm, and threshold
distance at the top of the device ranged from 42 to 58 cm.
The MF threshold distance in front of the water heaters
ranged between 12 and 27 cm, threshold distance at
45°angle from the frontal surface ranged from 12 to 26
cm, threshold distance at the back of the instrument ranged
from 11to 23 cm, while threshold distance at the top of the
instrument ranged from 10 to 21 cm. The EF threshold
distance in front of the table lamps ranged between 29 and
46 cm, threshold distance at 45°angle from the frontal
surface ranged from 11 to 16 cm, threshold distance at the
back of the instrument ranged from 14 to 28 cm, and
threshold distance at the top of the instrument ranged from

Table-7 gives Threshold values of EF and MF as
well as the magnetic field (maximum values) of home
appliances taken from various cell phone chargers in
Dhaka. Eight different chargers were investigated:
Xiaomi, Nokia, Samsung, HTC, ASUS, Oppo, and
Huawei. The magnetic fields ranged between 12 mG to
233 mG. The highest magnetic fields were found for
Xiaomi brand charger with 233 mG, while the lowest was
for Nokia brand having a magnetic field of only 12 mG.
ASUS brand charger also was above 100 mG having 175
mG while Samsung model ETA3U30EBE showed
magnetic field value of 218 mG. Figure-5 data were taken
from Table-7 with magnetic field maximum values in mG.

DISCUSSIONS
It was found from the results that the magnetic
fields are considerably higher than the threshold limit. Due
to the type of wiring in the ceiling and floor, all the rooms
had a higher magnetic field than the threshold value. Most
of the places in residential locations are occupied by
members of the family including children and they get
exposed to the above threshold level magnetic fields. We
have in mind to include other places of Bangladesh for the
study to continue.
Possible risk to health can be produced either as a
consequence of the contact of the human body to NIR or
by interaction with technical devices, which are
themselves influenced by NIR, increasing health hazards
(interference with electro medical machines, accidental
activation of electrical detonator and explosion of
combustible ingredients). This is of concern if the persons
involved are not conscious of the possible risk to be
incapable of identifying it.
CONCLUSIONS
From the above results, it has been achieved that
in many cases the magnetic field has crossed a threshold
value. The electric field also has a higher threshold value
in some of the equipment. Also, the magnetic field
maximum exposure was over 200 mG in many cases.
Proper wiring should be carried out corresponding to the
building code 2012. It is hoped that this survey will be
helpful as a preventive measure for all of the people
residing in Dhaka so that more protective measures are
taken for future dwellings.

The Significant concerns has been raised about possible health effects from exposure to radiofrequency (RF) electromagnetic fields specially after the rapid introduction of modern amnesties like the mobile telecommunication systems. There are many epidemiological studies of the possible adverse health effects associated with environmental exposure to extremely low frequency (0-300 Hz) non-ionizing radiation such as that emitted by power cables and electrical substations linking such exposure to leukemia, brain cancer, male breast cancer, skin cancer and eye melanoma. Far less attention has been paid to health hazards from environmental exposure to radiation in RF range (100 kHz-300GHz) at field strengths much below to these required to produce thermal effects. Laboratory studies in this area have also been confusing and conflicting. While some animal studies suggest that RF fields accelerate the development of cancers, other studies found no carcinogenic effect. There is an urgent need for extensive, well conducted epidemiological and laboratory studies. Cell phones are being used all over the world as it has made the life easy for all walks of life including academic, office, and business. Millions of cell phones are also being used in Bangladesh. EMF is also emitted by cell/mobile phones. There has been no such study performed in Bangladesh. The data were collected from various places in Dhaka city, Bangladesh. Both Electric and Magnetic fields were measured for cell phones. Both epidemiological survey and EMF measurements were done for these cell phones. These results showed that in many cases the magnetic field radiated from the different sources are greater than the threshold limit and cell phone users suffered from various types of ailments insomnia, pain in hands, headaches etc. due to prolonged exposure to EMF. Also smoking contributed to their overall health problems.

As the world is being industrialized and technological revolution continues, there has been an unprecedented increase in the number and diversity of electromagnetic sources. While all these devices have made our lives richer, comfortable and easier, they have been accompanied by concerned possible health risks due to their electromagnetic field (EMF) emission. ElectroMagnetic 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. CRT monitors are still being used in various computer composing shops, photocopy machine shops. Their EMF health effects have not been studied in Bangladesh. The data were collected from various places in Dhaka, Bangladesh: Banani Super Market, Mohakhali, Farmgate Green Road, Nilkhet and Uttara. Both Electric and Magnetic fields were measured for CRT monitors. These results showed that in many cases the magnetic field radiated from the different sources are greater than the threshold limit.

A non-Government organization in Bangladesh with about 30 employees rented a 6 storied building for its office in Dhaka. Soon after moving to this building several employees complained of headache, uneasy feelings and depression. It was reported that people working in 2nd and 3rd floors had greater complains than people from 1st and 4th floors. It was observed that an 11 kV power transmission line passed beside the building at the height of the 2nd floor at a distance of about 8 ft. People whose seating were nearest to the 11 kV line had greater complains than people in distant positions on the same floor. This prompted us to carry out a detailed investigation into the magnitudes of magnetic field present at different locations in the building.

Mobile Phone/Cell Phone has become an essential part of modem life style all over the world.people from all aspects of life are using mobile phone; as a result, the whole world has become into a global village which is a great contribution of mobile phone to human society.The use of mobile phone is increasing every day numbering more than 6 billion by 2014according to International Telecommunication Union (ITU). There is general public concern that Electromagnetic Radiation (EMR) from mobile phone and tower is harmful for human which may cause cancer, Brain tumors, Alzheimer, Parkinson's, Fatigue, Headache, Insomnia, etc. EMR from mobile phone causes health hazards due to its thermal effect but the mechanism is still not clear. More research is needed to understand the mechanism. Many countries of the world have taken precautionary measurements by making laws to protect their citizens from undue exposures. Bangladesh should also have such laws otherwise disaster on health may take place on the future generation.

Significant concerns has been raised about possible health effects from exposure to radiofrequency (RF) electromagnetic fields specially after the rapid introduction of modern amnesties specially the mobile telecommunication systems. The biological effects of low level EMF and a possible potential relation various diseases specially blood cancer causation are controversial. There are many epidemiological studies of the possible adverse health effects associated with environmental exposure to extremely low frequency (0-300 Hz) non-ionizing radiation such as that emitted by power cables and electrical substations linking such exposure to leukemia, brain cancer, male breast cancer, skin cancer and eye melanoma.

Laboratory studies in this area have also been confusing and conflicting. While some animal studies suggest that RF fields accelerate the development of cancers, other studies found no carcinogenic effect. Obviously, there is an urgent need for extensive, well conducted epidemiological and laboratory studies. Photocopy machines are being used all over the world as it has made the life easy for academic, office, business. Hundreds of photocopy machines are also being used in Bangladesh. EMF is also emitted by photocopy machines. There has been no such study performed in Bangladesh. The data were collected from various places in Dhaka city, Bangladesh: Banani Super Market, Mohakhali, Farmgate Green Road, Nilkhet and Uttara. Both Electric and Magnetic fields were measured for photocopy machines. Both epidemiological survey and EMF measurements were done for these locations. These results showed that in many cases the magnetic field radiated from the different sources are greater than the threshold limit and photocopier operators suffered from various types of ailments like indigestion, vomit, insomnia, pain in hands and legs, stomach ache, mental depression, skin disease, cataract, sexual problems, hairs turning white etc. due to prolonged exposure to EMF. In many of the photocopier shops the operators were working in congested space with lots of machineries around. There are many devices and power lines around them, having a congested environment and low circulation of air. Also smoking contributed to their overall health problems.
