Question

1. It is popularly believed that wireless technology was created in the year 1880 when Alexander Graham
Bell and Charles Sumner Tainter invented the telephone. In that moment they changed the very course of
human civilization. Today you would be hard pressed to find an adult or even a child who does not have
access to mobile technology.
2. Wireless communication is the transfer of information or power between two or more points that are not
connected by an electrical conductor. The most common wireless technologies used radio waves. With
radio waves, distances can be short, such as a few metre for Bluetooth, or as far as millions of kilometres
for deep space radio communications. It encompasses various types of fixed, mobile and portable
applications, including two-way radios, cellular telephones, personal digital assistants (PDAs) and wireless
networking. In fact, all our Wi-Fi devices also emit radio waves.
3. Wireless networks are gaining popularity due to their convenience. This ease of connectivity comes at a
price. Ongoing research has identified that signals from a wireless network are potentially dangerous to
humans. The constant proximity to wireless signals can cause headaches, insomnia, cardiac arrest and other
health issues. Researchers have established that Wi-Fi network signals predominantly affect the lower half
of the human body and can trigger liver and pancreatic cancer.
4. In 2011, the World Health Organisation’s International Agency for Research on Cancer classifies
wireless radiation from cell phones, baby monitors, tablets, cell towers, radar, Wi-Fi etc. as class 2B
carcinogens. This class 2B carcinogens classification applies to appliances with an operating frequency
ranging from 30 kHz to 300 GHtz. This means all this while, as we were scrolling through online
entertainment, we have been sitting on a ticking time bomb.
5. With the rapid growth of mobile phones devices in the market, technology has developed in such a way
that it has ended up creating a horrifying situation for the human body. The normal biological system of the
human body has not developed in any way to adapt to or protect against harmful radio waves.
6. This has led to a rise in serious ailments such as diseases of brains like cancer, brain tumor Alzheimer
disease, Parkinson disease and so on. Not to forget the short-term effects like hormone disruption, loss of
concentration ,impairment of cognitive function, behavioural problems, attention deficit; and long term
effects like DNA damage ,male infertility.
7.For children, the wireless devices have even more grave consequences because they have thinner bony
skulls, more aqueous bodies /brains ,higher rate of cell turnover and hence their neural system are not
completely developed. Beyond physical impairments, children are also vulnerable to stunted socio-
emotional, cognitive and behavioural development.
8. Given the ubiquity of technology in today's society and importance of this issue for policy and practice,
it is essential to understand the impacts of technology used on the developing brains and bodies of children
in the 21st century in order to guide policy delineating safe and effective use.

Answer 2

Question:

Q. Name the class 2B carcinogens given in the passage.

Answer:

Wireless radiation from cell phones, baby monitors, tablets, cell towers, radar, Wi-Fi etc. are considered as class 2B carcinogens.

Explanation:

• Wireless networks are becoming more and more popular because of their convenience. This easy connection comes at a price. Ongoing research shows that signals from  wireless networks are potentially dangerous to humans. Constant proximity to wireless signals can cause headaches, insomnia, cardiac arrest, and other health problems. Researchers have found that signals from Wi-Fi networks primarily affect the lower half of the human body and can cause liver and pancreatic cancer.
• In 2011, the  International Agency for Research on Cancer classified Radio emissions from cell phones, baby monitors, tablets, cell phone masts, radar, WLAN, etc. as Class 2B Carcinogen. This classification as a Class 2B carcinogen applies to devices with operating frequencies between 30 kHz and 300 GHz.
