Cell phone radiation: Avoid using the phoneChina cell phones: have the highest radiation value
The BfS recommends minimizing radiation in the immediate vicinity of the body in any case.
These are the most important tips for avoiding radiation:
1. Pay attention to the SAR value
Which rays are we talking about? Smartphones use high-frequency electromagnetic fields to send and receive voice and data. The smartphone user does not feel any of this immediately, but he does absorb energy, the so-called specific absorption rate (SAR). This value must be specified for all smartphones and tablets. According to the BfS, the recommended maximum value is two watts per kilogram of body weight. For every available smartphone, the SAR value from two measurements must be specified – when making a phone call to the ear and when wearing the device on the body.
The values can be found in the operating instructions and on a database of the Federal Office, which is updated regularly and is available online. According to this, the value for the Samsung Galaxy S9 + model is 0.29 W / kg at the ear and 1.35 W / kg at the body at a distance of 0.5 cm. Apple’s iPhone X is 0.92 on the ear and 0.95 on the body. According to the list, Huawei’s P20 Pro is 0.73 on the ear and 1.22 on the body.
According to BfS spokesman Lauer, all values are inconspicuous. Modern devices with LTE or UMTS have less radiation than older devices that transmit in the GSM standard. “This is also due to the device design,” explains Lauer. “The larger screens increase the distance between the antenna, which is often installed in the lower part of the housing, and the measuring probe, which reduces the measured SAR value.”
2. Rules of conduct for reducing radiation
But how can cell phone radiation be reduced? Manufacturers of special covers or jackets advertise protecting people from radiation. “Such accessories cause the smartphone to increase its transmission power in order to maintain the connection,” says Bernd Theiss, head of testing at the “connect” specialist magazine, on the other hand. “Then it sends all the more radiation towards the user.” In contrast, simple rules of conduct can significantly reduce radiation.
The basic requirement is a smartphone with the lowest possible SAR value. If the value is below 0.6, the experts speak of a low-radiation device. According to the BfS, around 55 percent of current smartphones are below this value. However, according to expert Lauer, the smartphone is used longer and more intensively than it used to be. Radiation exposure can also be reduced by using the landline phone instead of the smartphone as often as possible.
3. Headset and airplane mode
During operation, the antenna should be as far away from the head as possible. A headset is recommended for this. When the smartphone is not in use, it should not be worn on the body.https://123helpme.me/community-service-essay/ Here the “connect” expert agrees: “Every doubling of the distance reduces the remaining radiation to a quarter.” Therefore, the bedside table next to the pillow is not a good place if the device remains ready to receive. If the cell phone serves as an alarm clock, one should activate the airplane mode, so the BfS.
Since cell phones reach their maximum radiated power when reception is poor, you should avoid making calls or surfing in poorly developed areas, in the car or during a train ride through tunnels. According to the BfS, the power of the electromagnetic waves with a wireless connection via WLAN or Bluetooth is significantly lower than with a normal cellular connection.

The smartphone boom does not go past children either. The Federal Office advises protecting the little ones from high-frequency electromagnetic radiation. If possible, the WLAN network should be used and the mobile data should be switched off as often as possible. The radiation, about the consequences of which hardly any institution can make conclusive statements about the consequences for young and old, is reduced. Better safe than sorry.

The environmental association BUND has sued a federal authority for the approval of plant protection products that endanger bees.
As announced by the Federation for the Environment and Nature Conservation Germany (BUND), the lawsuit before the competent administrative court in Braunschweig is directed against the Federal Office for Consumer Protection and Food Safety (BVL).
Ministry approved agents containing glyphosate
The Federal Office, which is part of the Ministry of Agriculture, approved 18 plant protection products in February until the end of 2019. Among them is one that contains the controversial active ingredient glyphosate.
According to the BUND, the approved agents include the insecticide Alfatac 10 EC with the active ingredient alpha-cypermethrin, which is classified as dangerous to bees and harmful to populations of relevant beneficial insects such as beetles and wild bees. At the beginning of April, the BUND asked the authorities to withdraw approval for the insecticide. The BVL did not do this. Therefore, the lawsuit against the approval has now been made, by means of an emergency application.
Judgments: Studies on cancer risk of glyphosate need to be publishedBee deaths: Here’s how you can help the bees
“At the beginning of May, the World Biodiversity Council showed with its report how threatened our flora and fauna are,” said BUND Chairman Hubert Weiger. “Against this background, we consider it more than irresponsible to authorize a pesticide that is harmful to bees.” The granted approval is illegal. The Federal Environment Agency did not give the necessary consent.

Kourou (AP) – The “Cheops” mission to explore distant planets started one day late. The satellite lifted off from the Kourou spaceport in French Guiana on board a Soyuz rocket on Wednesday morning German time.

“Cheops” is said to observe bright stars that are known to be orbited by planets. The satellite will then analyze these so-called exoplanets in more detail. The planned launch of the rocket was canceled on Tuesday due to a technical problem.
So far, scientists know about 4000 such exoplanets. “While others are satellite hunters,” Cheops “is a small mission aimed at characterizing these well-known exoplanets,” explains the Science Director of the European Space Agency Esa, Günther Hasinger. The only thing known about many of the exoplanets is that they exist.

At noon, “Cheops” was successfully released. “There was an outcry of enthusiasm here. I had tears in my eyes for joy,” said Hasinger, who was also on site in Kourou. Everyone is incredibly relieved. “Everything is fine with the baby.” The first correct measurements are then expected to begin in spring.
The space telescope will fly at an altitude of around 700 kilometers and will be controlled from Spain. There the satellite was also built by Airbus Defense and Space. The scientific operating center is in Switzerland. The mission is a partnership between ESA and its member country Switzerland.
On Tuesday, the scientists still had to tremble. The Soyuz missile did not take off as planned, the countdown was stopped an hour and 25 minutes before takeoff. It wasn’t until hours later that it was clear: there would be another attempt on Wednesday. This has now been successful – the rocket disappeared with a light tail in the still dark morning sky of French Guiana.
“I prefer a take-off to be aborted if there are any doubts. It’s like being on a plane,” says Nobel Prize winner Didier Queloz from Switzerland. In 1995 Queloz and his colleague Michel Mayor discovered the first exoplanet orbiting a sun-like star. For this they were awarded the Nobel Prize in Physics in 2019. Queloz was on site in Kourou on Tuesday and hoped that the start would only be postponed so that he could still be there live. This hope has now been fulfilled for him.
The Nobel Prize brought new attention to the study of exoplanets, he says. Science is a game of chance, you never know what you will discover, according to the Nobel Prize winner. That is great fun. There are many known exoplanets. “We call them Super-Earth and Mini-Neptune and we don’t really know what they’re made of.”
That should change now. “Cheops” (Characterizing Exoplanet Satellite) is said to focus primarily on stars whose exoplanets are between Earth and Neptune in size. Thanks to “Cheops”, astronomers should be able to determine roughly the size of the planets. The space telescope measures the so-called transit depth. This is the decrease in the measured brightness of a star caused by a passing exoplanet. It is directly dependent on the size ratio between planet and star.
With the new data from “Cheops” and already known information about the mass of an exoplanet, scientists also want to draw conclusions about the composition and structure of the planet. “Cheops will also examine some stars where we know they have planets, but where we have not yet found any transits,” says Esa Science Director Hasinger.
This is where “Plato” and “Ariel” come into play. The two follow-up missions are scheduled to start in 2026 and 2028. “The big question is, the Holy Grail, so to speak, whether there are other planets somewhere that might be home to life,” says Hasinger. “” Plato “in particular is a planet hunter.” Plato “has the goal of finding the second earth.”
“Cheops” is “a small but fine mission,” emphasizes the expert. The satellite weighs around 300 kilograms. The German Aerospace Center DLR contributed two modules of the satellite. “Cheops” was shot into space together with other satellites – including the nanosatellite “OPS-SAT”, a small space laboratory. It was also sent into space by ESA and designed by TU Graz, among others.
For Borussia Dortmund, the fight for a place in the knockout round of the Champions League is a key game. With a win at Club Bruges on Wednesday (9 p.m. / Sky), the Bundesliga team in Group F could overtake the second from Belgium. After three clear victories over FC Schalke (3: 0), St. Petersburg (2: 0) and Bielefeld (2: 0), the Revierclub is starting the game with increased confidence. However, he has to do without defense chief Mats Hummels in the third group game. The use of striker Erling Haaland, who recently complained about knee problems, is to be decided at short notice.
Germany and Belgium have been connected to a power line since Monday. The 90-kilometer underground cable can transmit 1,000 megawatts of power, which corresponds to the electricity consumption of a city with a million inhabitants, said the transmission network operator Amprion. The endpoints are the Oberzier substations in the Rhineland and Lixhe north of Liège in Belgium. A test run is currently ongoing. The line for the European electricity market will be available from November 18, and electricity trading will begin from December 8.
The electricity bridge will help the European energy markets grow closer together, explained Amprion. This facilitates the integration of renewable energies, strengthens the security of supply in both countries and the economic attractiveness of the Aachen-Cologne region.
Prime Minister Armin Laschet (CDU) and the Belgian Energy Minister Tinne van der Straeten attended the symbolic ceremony on Monday. “The new bridge over 90 kilometers connects North Rhine-Westphalia and Belgium and thus Europe in a completely new way,” said Laschet.
Despite the renewed partial lockdown, Wacken co-founder Thomas Jensen hopes that his festival can take place again in 2021. “All of our fans, all of our employees, all of our artists are waiting for things to start again,” said Jensen of the German press agency.
In 2020 the internationally known Wacken Open Air (W: O: A) had to be canceled due to the pandemic. The festival is scheduled to take place again at the end of July 2021 and, according to the organizers, is already sold out. More than 90 percent of the visitors who had a ticket for this year exchanged it for a ticket for 2021. If everything works out, they can look forward to the Dropkick Murphys, Slipknot, Judas Priest and Lordi, the Finnish winners of the Eurovision song contest from 2006, as the organizers announced.
If Corona is still an issue in summer 2021, Jensen sees himself and his team well prepared. According to the Wacken organizer, they even have mobile disinfection stations from the time of the swine flu.
According to its own information, the Wacken team also exchanges information with virologists and organizers from countries such as Hungary and Denmark in an international task force. “We already think of scenarios: Can you form cohorts? Can you divide the terrain into sectors?”
Financially, the Wacken Festival has gotten through the crisis to some extent. Short-time working saved a lot of costs, says the organizer. The nationwide ban on events made it clear at an early stage that the metal spectacle could not take place this year. “It would have been worse if we had gotten the ban a day before the event,” said Jensen.
Following a decision by the EU Commission, Deutsche Bank is allowed to sell its IT subsidiary Postbank Systems to the Indian software service provider Tata Consultancy Services (TCS). The takeover by a Dutch TCS subsidiary did not lead to any competition concerns, the EU Commission announced on Monday.
At the beginning of November, Deutsche Bank announced that Postbank Systems, a Bonn-based company with around 1,500 employees, was moving under the TCS umbrella. The separation is part of the corporate restructuring that Deutsche Bank ordered in mid-2019. The Frankfurt parent company is also merging its IT infrastructure with that of Postbank, so that Postbank Systems’ tasks are shrinking. A total of around 18,000 jobs at Deutsche Bank are to be cut in the course of the restructuring.
