Two U.S. government agencies are giving conflicting interpretations of a safety study on cellphone radiation: One says it causes cancer in rats. The other says there’s no reason for people to worry.
No new research was issued Thursday. Instead, the National Toxicology Program dialed up its concerns about a link to heart and brain cancer from a study of male rats that was made public last winter.
The Food and Drug Administration, which oversees cellphone safety, disagreed with the upgraded warning. And “these findings should not be applied to human cellphone usage,” said Dr. Jeffrey Shuren, FDA’s chief of radiological health.
What’s most important is what happens in humans, not rats, said Dr. Otis Brawley, chief medical officer of the American Cancer Society.
“The incidence of brain tumors in human beings has been flat for the last 40 years,” Brawley said. “That is the absolute most important scientific fact.”
The original study
In a $30 million study, scientists put rats and mice into special chambers and bombarded them with radiofrequency waves, like those emitted by older 2G and 3G phones, for nine hours a day for up to two years, most of their natural lives.
The levels the rodents experienced were far higher than people are typically exposed to.
Last February, the National Toxicology Program said there was a small increase in an unusual type of heart tumor in male rats, but not in mice or female rats. The agency concluded there was “some evidence” of a link. Also, the February report cited “equivocal evidence” of brain tumors in the male rats.
Thursday, the agency upgraded its description of those findings. The heart tumor increase marked “clear evidence” of cancer in male rats, it announced. There is “some evidence” of brain cancer.
The change came after the agency asked outside experts to analyze the findings.
“We believe that the link between radio frequency radiation and tumors in male rats is real, and the external experts agreed,” said John Bucher, the toxicology agency’s senior scientist.
While his agency said the risks to rats don’t directly apply to people, the study raises safety questions.
The FDA immediately disagreed, firing off a press release assuring Americans that “decades of research and hundreds of studies” has made the health agency confident that the current safety limits for cellphone radiation protect the public health.
Plus, FDA pointed out confusing findings from the rodent study — such as that the radiated rats lived longer than comparison rats that weren’t exposed to the rays. The toxicology agency said it appeared that the radio frequency energy helped older rats’ kidneys.
There’s a reason two different government agencies are clashing — they’re asking different questions, said George Washington University public health professor George Gray.
A former science chief for the Environmental Protection Agency, Gray said the toxicology program examined how cellphone radiation affected animals. By looking at what it means for humans, the FDA “brings in more sources of information and data than just these recent tests in rats and mice,” he said in an email.
So are cellphones safe?
“I’m calling you from my cellphone,” noted the cancer society’s Brawley.
He pointed out one well-known risk from cellphones: Car crashes when drivers are distracted by them.
As for cancer, if people are concerned, they could use earphones or speakers, he said.
Those who study risk aren’t hanging up.
“My family and I won’t change our mobile phone habits based on this news,” said George Washington’s Gray, co-author of the book “Risk: A Practical Guide for Deciding What’s Really Safe and What’s Really Dangerous in the World Around You.” (VOA)

An energy meter, also known as a Watt-Hour Meter, is a device that monitors the level of electrical energy or gas consumed by users. Utilities are among the agencies that place these devices in various locations such as houses, businesses, organizations, and commercial properties to charge for the power consumed. You can always know how much is gas or electric cheaper by contacting a utility company.
Electronic Energy Meters
When compared to traditional mechanical meters, these types of measuring equipment are more accurate, have a faster processing time, and are more trustworthy. When attached to a source, it uses less power and begins measuring immediately.
Analog or digital meters are both possible. Analog meters transform energy to proportionate frequency or pulse rate, which is then combined by counters inside the device. A high-end processor directly calculates power in a digital electric meter.
Logic circuits combine the power to obtain the energy as well as for testing and certification purposes. The frequency or pulse rate is then calculated.

Smart Energy Meters
It is a cutting-edge metering technique that entails installing intelligent meters that read, process, and relay information to clients. It monitors energy usage, changes the supply to consumers remotely, and digitally manages the maximum energy usage.
For greater performance, smart metering systems make use of modern metering infrastructure system technology. These meters limit the number of times you have to go to the place to get your monthly reading.
In these smart meters, modems are utilized to enable communication technologies like phone, wireless, fiber cable, and power line communications. Another benefit of smart metering is that it eliminates the possibility of tampering with energy meters, which could lead to unlawful power usage.

Working of The Meter
The conventional electric meter looks like a clock and keeps track of how much electricity you consume. A series of microscopic gears inside the meter moves as your home takes electricity from the power wires. The numbers on your meter that you notice when you look at it indicate the number of revolutions.
The quantity of electricity utilized determines the speed at which the rotations occur. The velocity of moving gas in the pipeline is measured by a gas meter. As the gas flow rate increases, the dials speed up.

How Often is Meter Read?
Unless the meter is a consumer-ready meter, the government will demand utility companies read user meters quarterly. If the consumer checks the meter, the utility is asked to read it at least once a year. Almost every month, many utilities try and read their customers' meters.
If the meter isn't read, the utility might issue an estimated charge based on the previous usage. Keep bushes and plants away from the meter and allow access to the meter reader if your meter is within your home. All utilities demand their meter readers to have an employment ID as a security measure.

Responsibility of Meter
The utility provider is in charge of meter installation as well as the gas and electric lines that go up to the meter. The wires from the meter to the customer's premises are his responsibility.Please call your gas or electric utility if your meter is broken or displays evidence of tampering. Manipulation with a meter is prohibited and may result in service termination, legal punishment, or both.

A hilarious rhyme that children often chant cheerily while jumping around, Jack and Jill is another example of the dark history covered up in light-hearted rhyme. Instead of England though, this is a rhyme that sheds light on the history of France.
Unlike other rhymes, the rhyme is part fiction and part history, since only the first two lines can be taken as an allusion to the past.
"Jack and Jill went up the hill to fetch a pail of water,
Jack fell down and broke his crown,
And Jill came tumbling after."
King Louis XIV ruled over France in the late 18th century and was called out for treason. He had failed to uphold the economy of France. His spouse Marie Antoinette was an equally powerful influence in the monarchy but could not do anything when her husband was convicted.

The French are famous for the guillotine, and Louis XIV was beheaded on this device. This act of executing a monarch is why the rhyme has the line "Jack fell down and broke his crown". The guillotine, at this point in history, was kept outside the city, and the journey to it was long and tedious. It was ideally located on a hill, so that the entire city of Paris could witness the execution of the accused.
Louise XIV is believed to have been dressed and taken on the long journey up to the guillotine, where his hair was cut off and he had to renounce his authority. He bid farewell to his friends and was followed up the hill by a crowd holding pikes and bayonets, to prevent his escape. He was then executed as the last monarch of France.

A few months later, when the hue and cry of Louis XIV's death has died down a little, but the political situation of France was no better, his wife, Marie Antoinette was also executed at the guillotine for her role in the fall of France. And this event alludes to the line, "Jill came tumbling after".
The rest of the rhyme is a fictional account of a moralistic idea for children, as a way to tell them to be careful of where they engage in play. Since a large part of the rhyme seems like a story of two children who have had an accident in play, that is how the rhyme has survived and the history behind it, has been forgotten.
