EFFECTS OF RADIO WAVES

WHY THIS TOPIC?

• Cell phone and wireless technologies is one of the most popular technologies of this century.

• The effects of this technology is unknown since it’s relatively a recent invention.

• It is extremely important for youngsters to do more research on this issue since it is us who use this technology the most and at a young age.

EXPERIMENT SHOWS PLANTS WONT GROW NEAR WI-FI ROUTER

• Trays filled with seeds of Lepidium Sativum, a type of garden cress were kept in a room with a wifi router and one without routers, with all the other conditions the same.

• The cress seeds placed near the router had not grown. Many of them were completely dead, while the seeds in the other room thrived.

RISK TO CHILDREN AND PREGNANT WOMEN

Children are more vulnerable as:

Children using mobile phones absorb as much as double the amount of radiation through their heads as adults. Dr. Om Ghandi, a leading scientist and professor of electrical engineering at the University of Utah found that young children under 10 years of age could absorb radiation across their entire brain. He found that more radiation is able to go past the ear and into the head since a child's ear is thinner and the telephone is closer to the head. All it takes is two millimeters difference," Dr Ghandi said.

WAYS OF SHIELDING YOURSELF:

This operates like a stethoscope, transmitting the information to your head as an actual sound wave.

This prevents wires from going all the way up to your head, thus reducing microwave radiation exposure.

• Safe Space Cell Phone Protector

• It is a small emf dampener, attached to the back of your phone

• The harmful emfs are converted to safe signals protecting you from toxic transmissions

MEASURES WE CAN TAKE:

• Switch to CDMA usage because this reduces the radiation by a considerable amount

• Maintain ample distance from cell towers

• Promote radiation shielding techniques and prevention techniques

• Being the first generation to deal with this technology extensively, it is our duty to spread awareness about it’s potential risks

• Trusting a technology that emerged recently blindly with our health and life is not a smart thing to do

HOW CAN WE AVOID THESE RADIATIONS?

Buy low.Choose a cell phone with a low SAR rating. SAR stands for specific absorption rate, which measures the strength of a magnetic field absorbed by the body. If you don’t have your instruction manual, which is where that number should be (but isn’t always), you can find SAR listings at the Federal Communications Commission website or you can request SAR information from the manufacturer or your carrier.

Put them on speaker.Anything you can do to keep the cell phone as far away from your head as possible will reduce the energy or power level because the farther away you are from the antenna, the lower the signal. Whenever possible use speaker phone mode or a hands-free kit with a wireless air tube nearest the earpiece.

Use your words.Text whenever you can — it limits the duration of your exposure and keeps the phone farther away from your head and body When you text, don’t keep the phone in your lap, however. There have been an increasing number of studies that have found damage to sperm vitality and motility in men who keep their cell phones in their pockets.

Go offline.Make it a habit to turn the phone off when it’s not in use or to switch it into offline, standalone, or flight modes, which turn off the wireless transmitter but still allow you to use the phone or PDA for everything except making and taking calls or browsing the web or e-mail.

Make the switch.If you absolutely must place the phone against your head (and I definitely don’t recommend this), switch ears regularly while chatting on a cell to limit prolonged exposure on one side, which has been linked to increased risk of brain tumors and salivary cancers on the side of the head where the phone is usually held.

Avoid tight spaces.Don’t make or take calls in the car — which thankfully is becoming increasingly against the law because it creates distractions — in elevators, trains, buses, or underground. First, your cell has to work harder to get a signal out through metal, so the power level increases. And on top of the more powerful signal, any metal box like the car or an elevator will also cause the waves to bounce around, creating in effect a resonance chamber, boosting their intensity.

Keep an eye on the bars.Don’t use your phone when the signal is weak or when you’re traveling at higher speeds in a car or train; this automatically boosts power to maximum as the phone attempts to connect to a new relay antenna.

Keep it short. If your conversation is going to be long, use a landline. One study found that after two minutes, the brain’s electrical activity can be altered for at least an hour. Remember, brain tumor risk starts at a relatively low level of cumulative lifetime exposure.

Spend even less time on our PDA.Wireless devices such as the BlackBerry, iPhone, and Treo produce higher Extremely Low Frequency (ELF) electromagnetic field transmissions than cell phones because they rely on the energy from batteries to power up things like e-mail and Internet connections and color displays.

Dial, then stretch.Don’t place the cell phone on your ear while your call is connecting — that’s the time the phone is sending out its strongest signal.

Keep the cell out of the bedroom.Specifically, don’t sleep with your cell near your head. Remember, EMFs can reduce your body’s production of melatonin and with it a powerful free radical scavenger that can protect your cells from the DNA damage that can lead to cancer and other disease.
