1. Interpretation of Cell Tower Readings Measured by TERM Cell / TCIL vs. Safe level
for Health by Neha Kumar, Director, Nesa Radiation Solutions Pvt. Ltd.
Dear All,
I have been working on Cell Tower Radiation issue for the past 3.5 years along with my father Prof.
Girish Kumar from IIT Bombay. We have been studying the effects of cell tower radiation on humans
and environment and have prepared several reports and submitted the same to DOT and several officials.
My work can be seen at: http://neha-wilcom.blogspot.in/ . I also have a company NESA
Radiation Solutions Pvt. Ltd. through which we have been carrying out radiation measurements for
people in residences and offices and have seen a strong correlation between high radiation levels and
health problems.
Recently government has started carrying out radiation measurements for residents
through Telecommunications Consultants India Ltd (TCIL). However everywhere they measure, the
readings indicate that levels are within norm. This has led to major confusion among common people.
Please find the report prepared by industry/their associates for a building in Thane, Mumbai:
Figure 1 EMF report of TERM Cell for a building in Thane, Mumbai
Please note, government of India has adopted a very high radiation norm and what is safe from health
point of view is much lower. Operators are within the norm so they keep saying they are within safe
guidelines.
Efforts should be to convince the government to adopt better radiation norms.

2. Interpretation of the readings:
9.2W/sq.m = 9200 mW/sq.m - ICNIRP Guideline1998 for GSM 1800 - The Department of
Telecommunications, India adopted this norm in 2008
0.92W/sq.m = 920 mW/sq.m - 1/10th of ICNIRP - The Department of Telecommunications, India
adopted this norm from 1 Sept 2012
0.0001W/sq.m = 0.1 mW/sq.m - Safe from health point of view [According to Bioinitiative Report 2007
and recommendations of Antenna Lab, IIT Bombay]
0.185W/sq.m (-02dBm) = 185mW/sq.m - Maximum Reading Measured in this building [Flat No.1002
- Bedroom] (which is within the government norm hence operators have said that the levels are within
guideline) This reading is very high from health point of view. People have been complaining of health
problems like sleep disturbance, headaches, concentration problems, joint pains even above
0.001W/sq.m.= 1 mW/sq.m Above 0.01W/sq.m = 10 mW/sq.m, severe health problems and cancer cases
have also been reported in few years.
ICNIRP Guidelines are meant for short term exposure and not for long term exposure. In fact, the short
term exposure guideline is only for 6 minutes/day.
By extrapolation, 1/10 of ICNIRP is valid only for 6x10 = 60 min = 1 hour per day. People living close to
cell tower radiation are exposed to radiation 24x7.
Please go through the report: Guideline-Austrian-Medical-Assoc-EMF-syndrome.pdf –
http://www.scribd.com/doc/87308119
Page 9 mentions that greater than 1 mW/sq.m is very far above normal.
Figure 2 Guideline-Austrian-Medical-Assoc-EMF-syndrome - Page 9
According to Prof. Girish Kumar's report - http://www.scribd.com/doc/132189401 greater than
1mW/sq.m over a few years of exposure leads to health problems.
If you have any queries, please feel free to write to me.
With regards,
Neha Kumar

0.0001 Watt/m²= 0.1 milliWatt/m²= 100 microWatt/m²= Safe standard as per Bioinitiaitve Report 2007
[for Continuous Indoor Exposure] and recommended by Antenna Lab, IIT Bombay
For GSM 900: 0.45 Watt/m² = 450 milliWatt/m²- 1/10th of ICNIRP - Department of Telecommunications, India adopted this norm from 1 sep 12
For GSM 1800: 0.92 Watt/m²= 920 milliWatt/m²- 1/10th of ICNIRP - Department of Telecommunications, India adopted this norm from 1 sep12
ICNIRP Guidelines are meant for short term exposure and not for long term exposure. Short term exposure guideline is only for 6 minutes/day.
People living close to cell tower radiation are exposed to radiation 24x7.
