Specified criteria to prevent the risk of radiation emitted from mobile towers

The government has set standards to reduce the risk of radiation emitted from mobile towers. Keeping in view the health and safety of the people, the Telecommunication Authority of Nepal (TAN) has recently issued regulations in 2076 BS regarding the safety of the public and workers from electromagnetic radiation (EMR) generated from mobile towers.

The regulations passed by the board on December 3 have just been made public by the NEA. Along with this, the telecommunication service providers who install and operate mobile towers now have to make arrangements to emit electromagnetic radiation only as prescribed.



According to the regulations, different criteria have been set for the general public and business people working in the tower. It has been mentioned that the criteria for such radiation emissions should also vary according to the radio frequency range.

According to the regulations, the electric field strength at the level of 10 to 400 MHz should be 28 volts per meter for the base station of the mobile. Magnetic field strength should be 0.073 ampli per meter and power density should be 2 watts per meter square.

Similarly, 400 to 2,000 MHz, 2 to 300 GHz electric field strength, magnetic field strength and power density are different for normal people and workers. There is a provision to do.

Employees will now be required to provide safety equipment and measures to employees working at the base station of the telephone tower. NEA has also brought various safety measures and standards to be adopted while entering the accident zone in the new regulation.

Provision has been made to ensure that non-ionizing radiation exposure to the public is not exceeded by the maximum EMF exposure limit set by NEA while connecting and operating the cellular mobile base station using radio frequency in the tower. It has been mentioned that arrangements should be made around the tower so that it is not accessible to the public and the criteria set by the ITU should be met.

The service provider has to put up warning signs and labeling with information on the potential risks from emf exposure of the radio system connected to the tower and how to minimize the risk of such risks. Among such signs, RF yellow direction sign, information sign, warning sign, warning sign and 4 types of sign should be used in the tower.

According to the regulations, when connecting a tower on the roof of a building, the antenna of such base station should be at least 3 meters high. All these provisions are mentioned in the regulations applicable to the connection and operation of mobile networks based on Forge and FiveG.

The service provider also has to self-declare in the prescribed format after the service provider has connected the base station of radio frequency in the tower structure and submit it to the authority.

Provision has been made to perform objective analysis and simulation of RFEMF exposure before connecting the antenna to the tower site, evaluating the criteria of RF exposure and submitting the report.

NEA will monitor whether the prescribed provision has been implemented or not. It has been mentioned that the report from the monitoring will be made public. If the service provider does not follow the regulation, it will be punished according to the rules and regulations.

While operating the cellular base station connected to the tower, if the service provider is found to have violated the specified criteria regarding EMF exposure, the authority has made provision for immediate closure of the cellular base station connected to such tower.
