2. NON IONIED RADIATION:-
Non-ionizing (or non-ionising) radiation refers to any type of electromagnetic
radiation that does not carry enough energy per quantum to ionize atoms or
molecules—that is, to completely remove an electron from an atom or molecule.
Instead of producing charged ions when passing through matter, the
electromagnetic radiation has sufficient energy only for excitation, the
movement of an electron to a higher energy state.
CLASSIFICATION OF NONIONIZED RADIATION:-

3. TYPES OF NON-IONIZED RADIATION :-

4. COMMON SOURCES OF NON IONIZED RADIATION AND THEIR
ALTERNATIVES:-
• MAKE SURE TO TUNE
YOUR PHONE SETTINGS
SO THAT IT DOES NOT
TRANSMIT
CONTINUALLY
• BEAWARE OF SIGNAL
MODULATIONS
• SAR CAN BE DECEPTIVE
• AVOID BLUETOOTH
• TURN OFF YOUR PHONE
WHENEVER POSSIBLE
• CFL AND

5. COMMON SOURCES OF NON IONIZED RADIATION AND THEIR
ALTERNATIVES:-
• DIMMER SWITCH
PUT OUT A WIDE
RANGE OF
RADIO-
FREQUENCIES IN
THE KHz RANGE
WHEN TURNED ON
• AN ON-OFF
DIPOLE SWITCH IS
A BETTER
ALTERNATIVE,SINC
E IT DOES NOT PUT
OUT WIDE RANGE
OF RADIO
FREQUENCIES
• THE MICROWAVES THAT
LEAKS OUT OF THE
MICROWAVE OVEN ARE
VERY STRONG AND
POWER LINE MAGNETIC
FIELDS ARE ALSO HIGH
ALTHOUGH THE
MICROWAVE RADIATION
IS ONLY FOR THE SHORT
DURATION
• USE A PORTABLE OVEN
INSTEAD TO HEAT YOUR
FOOD

6. SAR:-
It is defined as the power absorbed for unit of mass and is given in watt for
kilogram [W/kg] or it represents the spatial average over all the exposed mass to
radiations in frequencies great than 10MHz.
Background:-
• explosive growth in the production of electronic gadgets
• A number of gadgets are used daily
• Exposure to low-frequency EMFs increased childhood leukaemia
• exposure of human brains to electromagnetic waves, can result
brain tumours
• extremely high SAR results in thermal effects
• Changes in gene expression associated

7. PROBLEMS ASSOCIATED WITH MONITORING OF NON IONISED
EXPOSURE :-
• Modulation
• Radiation pattern
• Frequency
• Polarization
• Leakage due to radiation
OBJECTIVE:-
Devise an electronic circuit that measures the amount of radiation
and relatively provides the degree of potential risk present i.e.to
design a meter or equipment that measures the Electromagnetic
Radiation level (RF) present in the environment and indicate the safe
level and unsafe level or it measure the non-ionic radiation.

8. SOFTWARES USED:-
1. Proteus 7.6:-
Proteus software is a electronics circuit simulation software and PCB
circuit board design software. . It is a complete integrated tool that
allows circuit board designers to enter the schematics, perform
various simulation analysis, take the schematics to PCB layout tool
and generate Gerber PCB file for PCB manufacturing. Another great
feature is that it supports micro-controller based co-simulation.
2 . Keil uVision4:-
The µVision IDE from Keil combines project management, make
facilities, source code editing, program debugging, and complete
simulation in one powerful environment.
3.ExpressPCB:-
The ExpressPCB Windows layout software makes designing PC boards
simple for the beginner and efficient for the professional.

2)DEVICE SPECIFICATION:-
1. Coil as a transducer(antenna) with 65 turns of wire of width 0.05mm
2. 8 bit A-D convertor 0831
3. Microcontroller 8051
4. 16X2 LCD display
5. 12V adapter ac-dc source

14. TEST PROCEDURES:-
1. The coil is appropriately placed at a distance from object whose radiation is to
be monitored.
2. The other end of the coil consisting of the filter and A-D convertor is interfaced
with the LCD display unit.
3. The device is then connected to supply via 12V adapter.
4. The corresponding switches are ON. The glowing led and LCD display indicates
that the device is working properly.
5. The display on LCD in percentage represents the radiation level along with the
linguistic level of radiation.

15. TEST RESULTS:-
• Radiation level of some household devices & Variation with respect to distance

16. GRAPHICAL ANALYSIS:-

17. CONCLUSION:-
1. After monitoring the radiation level it is clear that almost every
electronic device produce electromagnetic radiation.
2. As per graphical representation when distance increases the
value of radiation level decreases.
3. Now it is the topic of major concern that either we minimize the
use of them or take appropriate precautions for health.
4. Make sure that when we use such equipment maintain a certain
distance while operating them.
