Mobile towers, often referred to as base stations, have been installed in communities in significant numbers as a result of the increased usage of cell phones in recent years. These towers emit radiation in order to connect with other towers to make communication successful. According to the World Health Organization, these radiations can harm a person's health and, if exposed to them over an extended length of time, may contribute to the development of cancer. In addition to this, a number of incidents have also supported the link between mobile tower radiation and severe health problems in people. It appears that the growing number of cell phone towers in urban areas is reducing bird populations. This article will explain to you about Impact of Radiation From Mobile Phone Towers on Human Beings And Wildlife which will be helpful in preparing the Environment Syllabus for the UPSC Civil Service exam.

What is Mobile Tower Radiation?

• Radiofrequency (RF) waves are used by the electronic hardware and antennas on these towers to receive and send cell phone signals.
• RF waves have the capacity to heat body tissues at very high levels.
• However, cell phone and tower energy consumption are substantially lower.
• An antenna on a cell phone transmits a signal to the antenna of the closest base station whenever someone calls a cell phone number.
• This signal causes the base station to reply by allocating an open RF channel to it.
• The voice data is transmitted to the base station via RF waves.
• A switching center then routes the call to its intended recipient after receiving the voice signals.
• Following that, voice signals are passed back and forth throughout the call.
• RF waves created at the base station during calls are released into the environment, where individuals may be exposed to them.
• This happens when RF signals are transferred back and forth to the base station.

What is SAR?

• Specific Absorption Rate is the measure of how much radio frequency energy is taken in by the body while using a mobile phone, ensuring that radiation has no negative effects on health.
• The restriction that offers sufficient defense against occupational exposure has been determined to be a whole-body average SAR of 0.4 W/kg.
• The public exposure safety factor is increased by 5, resulting in an average whole-body SAR limit of 0.08 W/kg.
• The strictest international standards for mobile devices have been accepted by India.
• All-new mobile phone designs must adhere to SAR values of 1.6 W/kg averaged across 1 gram of human tissue as of today.

Impact of Radiation From Mobile Phone Towers On Humans

Cancer

• To examine the potential link between cell phone use and the risk of tumors, both malignant (cancerous) and nonmalignant, researchers have conducted a variety of demographic studies (not cancer).
• These stronger forms of radiation may cause cancer since the intensity of RF waves emitted by cell phone towers is insufficient to break chemical bonds in DNA molecules.
• Malignant brain tumors, such as gliomas, as well as nonmalignant tumors, like acoustic neuromas, meningiomas, parotid gland tumors, skin cancer, and thyroid gland tumors, have been identified.

Genetic Mutations

• When it comes to genes and genetics, radiation has negative consequences.
• It causes DNA strand damage, which leads to genetic disintegration over time.
• The degree of genetic mutation leading to changes in DNA composition varies depending on the amount and type of radiation one has been exposed to.
• If a person or animal is exposed to too much radiation through the atmosphere, food, or even water, their bodies are likely to have already absorbed the radiation.
• Because energy cannot be eliminated, it remains active once within the body.
• As a result of the mutation, one is extremely vulnerable to cancer.
• Children born to pregnant women suffer birth abnormalities caused by genetic mutations, such as low weight during birth.
• Severely deformed births and impairments in children, such as blindness, have also been observed.
• Radiation-induced infertility has also been reported as a side effect.

Other Impacts

• Joint Pain: Joint discomfort is observed to impact about 25% of all those who are affected.
• Non-thermal Effects: The transport of calcium and other ions across cell membranes results in non-thermal effects that are generated by radio frequency fields at levels too low to really heat things up.
• Physiological Illness: It is well recognized that such exposure causes additional psychological illnesses, such as weariness, nausea, irritability, headaches, and appetite loss.

Impact on Birds

• In comparison to the human body, a bird's surface area is larger than its body weight, hence it absorbs more radiation.
• Furthermore, because the bird's body contains less fluid due to its small size, it heats up quickly.
• Birds' navigation skills are disrupted by the magnetic field from the towers, so when they are exposed to EMR, they become disoriented and fly in all directions.
• Collisions with telecommunications masts cause a significant number of bird deaths every year.

Impact on Bees

• Suddenly disappearing bees with little explanation are a new occurrence.
• The bees simply leave the hive and don't come back, with little indication of disease or infestation, which has been observed all over the world.
• The issue is known as Colony Collapse Disorder (C.C.D.). The idea that honey bee colony collapse disorder (CCD) is caused by electromagnetic radiation from cell phones and their relay towers has been supported by studies.
• In fact, the biology and behavior of honey bees are being impacted by the enormous amount of radiation produced by towers and mobile phones.
• Radiation may affect the "waggle" dance that bees do to communicate with one another on honeycomb, which keeps them from going back to their colonies.
• A sudden fall in the number of commercial bees has recently been seen in Kerala, posing a major threat to beekeepers and harming apiculture.
• Similar incidents have been seen in Punjab, Bihar, and other regions of India; they have all been linked to the environment's rising electromagnetic pollution.

International Commission on Non-Ionizing Radiation Protection (ICNIRP)

• The International Commission on Non-Ionizing Radiation Protection (ICNIRP) is a global organization with a focus on non-ionizing radiation safety.
• The organization's tasks include figuring out the electromagnetic field exposure limitations for devices like cell phones.
• ICNIRP is a privately operated, non-profit scientific organization with a German charter.
• It was established in 1992 and still has a close relationship with the International Radiation Protection Association (IRPA).
• In order to provide protective advice on non-ionizing radiation, such as radio, microwave, UV, and infrared, ICNIRP screens and assesses scientific information and the latest findings.

Where does India stand?

• India is home to roughly one-fifth of the world's population, which accounts for the vast majority of mobile phone users there.
• As part of a nationwide connectivity network, these mobile phones send and receive signals to and from mobile towers.
• The maximum safe level of electromagnetic radiation that can be emitted by mobile towers is 0.5 milliwatts per square meter.
• This cap was severely exceeded in India in 2013, rising to 900 times higher.
• India now has a radiation exposure limit of 9.2 watts per square meter, which is higher than that of nations like China and Russia (0.4 w/sq m and 0.2 w/sq m, respectively).

Responsibilities of Stakeholders

• MoEF: In order to regulate the norms for notification of standards for the safe limit of Electromagnetic Radiation (EMR), the Ministry of Environment, Forest and Climate Change (MoEF) must notify the concerned agencies of the consequences of communication towers on wildlife and human health.
• State/ Local Bodies: Conducting an "Ecological Impact Assessment" before granting authorization for the construction of towers in wildlife and environmentally important places, which includes protected areas and ecologically sensitive areas.
• Routine monitoring and auditing in urban neighborhoods, educational, hospital, industrial, residential, and recreational establishments.
• State Environment and Forest Department: The responsibility for educating the public on the rules of mobile phone towers and the risks of EMR from them rests with the State Environment and Forest Department.
• Department of Telecommunications: Prevention of high radiation fields from crossing over.
• Within a kilometer of an existing tower, no new towers should be allowed.
• Cell phone towers and other towers emitting EMR should have their locations and frequencies made publicly available.
• Geographic Information System (GIS) mapping of all the mobile towers that must be kept up to date in order to track the bird and bee populations in and around the wildlife-protected area is recommended.
• The Indian standard on safe exposure to EMR needs to be improved, taking into account the literature on the effects on diverse living forms.
• To adopt higher standards and take precautions to reduce exposure levels.
• Other Agencies: Any research on the effects of EMF radiation on wildlife should be disclosed in order to help formulate the best possible policies.

Conclusion

A senior DoT official said thorough research on electromagnetic field signals has proved that it does not do any harm, in contrast to widely held beliefs that radiation from cell phone towers may be harmful to health. There are, however, always protection options available, such as aluminum foil that insulates from radiation on the exterior walls. Using wallpaper paste, a layer of aluminum foil can adhere to the exterior walls. Due to its density, other alternatives like lead can be employed. Any type of anti-radiation shielding must be properly grounded, and this is crucial. Although shielding with these materials might be simpler, it still requires extra work and meticulous effort.
