Some researchers in Department of Physics, Mizoram University are working on similar work. They used some detectors available in the market to measure the power radiated by Mobile towers at different locations, and at different distances from the tower. You may contact Prof. Zaithanzauva Pachuau who is the project investigator.

Dear Dr. Lalremruata,

Thank you for your quick response and suggestions. Can I have email ID of Prof. Pachuau?

Regards, Atanu

Dear Sirji,

Prof. Girish Kumar at IIT Mumbai works on cell tower radiation. Although people have questioned his findings, he may be able to supply reliable detectors.

Dear Thomas,

Thank you for your quick response and the suggestions. I am absolutely new to the field. We propose to study effects of LF EMF emanating from BTS on human circadian rhythm, sleep and cognition as function of the distance from the location of the BTS. We want to know the level of radiation at different distances, for example at 100, 500, 1000 and 1500 meters away from the BTS. That is the story. Should you like to know more about our project you are welcome to write us back. Please suggest what should we measure using less expensive gadgets?

Regards, Atanu

Dear Sir,

http://www.testequipmentdepot.com/usedequipment/hewlettpackard/spectrumanalyzers/3585a.htm 2500$ (HP system)

http://www.aaronia.com/products/spectrum-analyzers/?gclid=CPqGy7DQ3cYCFU2SfgodqakLXw (NF series for EMF, particularly 5030/5030S), 700-1500$ (these are very good at the price)

Cheap ones: http://www.norad4u.com/monitor/home-emr-meters (very cheap)

Apart from these, this one is good: http://www.radmeters.com/Tenmars-TM-196.html (400$). This would be my choice, if I had a very limited source of funding, yet wanted accuracyto some degree.

Since they are cheap, it could be possible to cross-check Tenmars high-end v/s Cornet ED85EXS. (200-400$)

You'll need a three-axis system, that has a very fast sampling rate and can measure CDMA/GSM/LTE.

One solution could be to start with a cheap RF/EMF monitor and then explore HP/Aaronia, once we know what is needed and what we lack. Also, professional EMF testing is available, if we hire someone from a company, and get a good look at the tester, the rest shall follow. The Aaronia meters also have data loggers, which would be useful.

Respectful regards,

Dear Thomas,

Thank you for your answer and explanation. In fact, we are not going to expose test subject to certain duration of exposure; rather we are interested in the subjects inhabiting around the BTS and receiving LF EMF radiation perpetually. Can you suggest study design and parameters to be investigated with reference to EMF?

Regards, Atanu

Priyo,

Thank you for suggesting number of low cost gadgets. I will explore how best they will support our proposed study.

Thank you, Atanu

Dear Thomas, 

Thank you for your suggestions and support.

Glad to be of help. If I have a vote, and keeping in mind the 2-5 lakh budget, I'd vote for Aaronia 5030S with data logger and extra probe. Additionally, most researchers recommend monitoring SAR from cell phones (palm/ head) at the end-user level along with measuring cell tower radiation.

I am thinking of buying either Cornet ED78S or Cornet ED85EXS [refer:  www.radmeters.com]. What do you think Priyo?

Dear Sir, 

The Cornet ED85EXS should give you a working start only, and help you determine the parameters quickly at a site to assess its suitability, EMF field, and its penetration to households within the area under study (and householders may initially be comfortable with a simple-looking small handheld instrument in their house). For readings that cannot be easily challenged for accuracy, the Aaronia 5030S with data logger and probe (Germany) should be within 1 lakh rupees and would be my recommendation. Since the price is low (12,000 for Cornet and 1 lakh for Aaronia), one could get both, the Cornet for quick preliminary handheld assessment for the initial identification of study sites, and the Aaronia for authoritative data logging. I have an idea, and I don't know if you'd like it, but one could take readings with the Aaronia at a particular household, and simultaneously measure EMF with many cheap Cornet devices at different locations over 24 hrs around the site. Any anomalies may be further investigated with the Aaronia.

Warmest regards,

Priyo

Dear Thomas,

Apparently,  the purpose of the project is to record EMF around a human being, and that has to be done at body level, inside and outside a house. The readings from the top of a high mast near a cell tower may not be representative of the EMF received by a person. My previous experience in human research indicates that householders may be trusted to leave expensive equipment undisturbed for recording  (e.g., actigraph).

Regards,

Priyo 

Dear Thomas & Priyo,

The human households are distributed/located around BTS. Our purpose is to find out if radiation is different at different radii with reference to the location of the BTS. We plan to measure sleep, circadian rhythm and cognitive abilities in humans living around the BTS. Even if we don't measure radiation we still can elucidate differences in biological variables among populations inhabiting at different distances from the BTS. What you people think about this?

Dear Sir,

I'd think measuring EMF would be essential for a counterbalanced study, with comparable groups that are located far away from cellphone towers and receiving lesser EMF from a BTS (or almost no EMF, e.g. Bastar). It would be even better if the study could be longitudinal, especially if a few families could be found that were staying near a BTS but were planning to move away, or vice versa so that the same variables could be studied in the same people before/during/ after proximity to BTS.

Given the history of previous studies involving BTS, you may expect stiff resistance and controversial comments from a certain section of the general public. Therefore, the experimental design must be very rigorous with as many ambient parameters measured as possible, e.g., ambient daytime/night-time light, temperature, EMF, sleep and shiftowrking/jet lag history, social events (e.g., parties and functions that last late into the night), alcohol, diseases/disorders, diet, time of meals, etc.

So, it would not be possible to conduct the study without measuring EMF, to discount it as a factor, or implicate it as one.

Warmest regards,

Priyo
