Urban lighting network on IEC poles as a source of "non-ionizing radiation"
Various aspects and possibilities of reducing the magnetic field levels resulting from the activation of urban lighting

1986 - Immigration to Israel
1987 to date - Various positions in the Electric Company, Dan District: Network Planner, Head of the Computer Database Section, and from 2001 to the present - Transformation Station Planning Officer, in this position responsible for planning the hate infrastructure of all new construction in the district.
In the field of electromagnetic fields ("electromagnetic radiation"):
2003 - 2016 - The treatment center in the district of Dan in reducing magnetic fields from the electricity grid. In this role he handled many dozens of complaints / special cases Regarding magnetic fields from the electricity grid.
Conducting courses at the Electric Company's school on reducing the levels of magnetic fields in the electricity grid
Conducting courses on the same subject at the Holon Institute of Technology as part of a collaboration between the Dan District and HIT for the transfer of practical knowledge to students in the past year.
Licenses and permits In the field: Engineer, engineer and permit to provide service in the field of ELF in accordance with the Non-Ionizing Radiation Law.
Summary
In the lecture, we will present an insufficiently known problem, resulting from the complexity of integrating the urban lighting network within the IEC's low-voltage network, which is built along the streets of Israeli localities. This combination is characterized not only by the use of the same support poles for the lighting network and for the IEC network, but also, for historical reasons, in the common use of the same "zero" conductor for the two networks.
An example of an integrated lighting network under the IEC distribution network, where the "0" conductor of the IEC network also serves as the "0" of the lighting network.
The lecture will review the issue of responsibility for the urban lighting network (municipality or IEC?). Because there have been a proliferation of cases of specific complaints about street lighting, because more than once the measurements of a magnetic field have indicated a significant increase in the levels of the magnetic field measured within homes close to the grid, immediately after turning on street lighting. Occasionally, the surveyors realized that before the lighting was turned on, the magnetic flux density levels were very low, and only for the lighting fixture, the magnetic flux density values increased up to 2 times more than the values that preceded the lighting. Of course each of the two activating factors: the electricity company and the municipality pointed to each other as the factor responsible for the necessary treatment in order to reduce the magnetic field to the levels expected in a normal situation.
Later in the lecture we will present the implications of this technical “sharing” for the two networks, both operationally and certainly in terms of creating unexpected magnetic fields in nearby homes. It will be shown here how the use of the "0" of the distribution network also affects the "0" of the street light, and in what situations the problem may be a built-in problem, which cannot be treated with simple means, and more "drastic" treatment is needed.
The rest of the lecture will address the issue of connecting the zeros of different distribution networks, belonging to different transformers, and the paradox created by the combination of the two networks: the connection between the zeros belonging to different networks, which may under certain circumstances This is not possible due to the need to ensure zero continuity of the lighting network.
At the end of the lecture, a number of options will be given for the treatment of the light network, in order to prevent an increase in the levels of the magnetic field beyond what is expected in normal mode.

Electromagnetic radiation and EMG fields from renewable energy production systems
Prof. Moti Haredim
Holon Institute of Technology HIT
Israel
Prof. Moti Haredim Head of School of Advanced Studies Faculty of Engineering Responsible for locating faculty members and recruiting students for special projects
Holds a doctorate in science from the Technion - Haifa. Areas of research of prof. Haredim are semiconductors, photonics of microwaves, computational methods in electromagnetics and analog communication systems. Prof. Haredim joined the Department of Communication Engineering in 1994 and since 2000 he has served as head of the department. Dr. Haredim is responsible for establishing the experimental research infrastructure at the RCQCE Research Center for Quantitative Communication Engineering. At this stage, the experimental research will focus on the nanotechnology development of semiconductor models with special isotopic properties.
Summary
So far, the radiation levels and magnetic field flux distributed from ordinary energy facilities such as transformers, electrical panels, uninterruptible power supplies and generators have been measured. The lecture will present the levels of radiation and magnetic field flux distributed from renewable energy systems such as photovoltaic cells and their associated systems, wind turbines for electricity generation, pumped energy and microwave transmission from space to the earth produced from solar energy. The lecture is based on actual measurements and computer simulations.
The lecture will present the benefits of renewable energy systems also in terms of radiation as most systems distribute very little radiated energy.

The Radiation from Wi.Fi. Access Point and Cellular Repeaters - Is it Safe within Education Institute?
Abstract
Low Power cellular repeaters and Wi.Fi Access Point (AP) transmitters are seldom found within education institutes in Israel (kindergarten up to high schools). These low-power transmitters have similar characteristics: TX power less than 1W (less than 30dBm), similar frequency range. Omnidirectional antennas installed in-door near or on the ceilings.
For some non-logical reason there is a fear in Israel to allow installation of such micro-transmitters within education institutes in Israel (kindergarten up to high schools). Concerned parents and municipal authorities prevent due to "radiophobia" installation of these low-power TXs.
The undersigned has gained experience in radiation measurements from such radiation sources. The measurement results are all the same - The radiation is so low that broadband radiation monitors are not sensitive enough for measuring it thus only narrow band measurement set (Spectrum analyzer and antenna) can be used to determine the quantity of the radiation strength and to allow comparison with the international exposure limits.
It was found that the radiation of which students are exposed to is less than 1% of the "Precautionary Principal" radiation level recommended by the Israel Environmental Protection Ministry. The question whether this radiation is safe or not is thus self-answered
