Everyone has always been worried about the potential impact of mobile phone and computer radiation on the human body. Today, PHP editor Xinyi will answer a common question for you: If 100 mobile phones are turned on at the same time, will the radiation amount be equivalent to that of a computer? We’ll delve deeper into this issue below to bring you the facts and help you understand the true effects of radiation on your health.
There is a certain amount of radiation when the mobile phone is talking, and it is very small when not talking. However, these radiations are very small and completely within the range that the human body (including pregnant women) can bear. 100 computers are not as big as the radiation you get from sunbathing.
This thing is not easy to estimate. The content of radiation actually refers to the energy of the radiation in the seawater. But we all know that the power of nuclear radiation is great, especially 1.28 million tons. It is said that the content of radioactive substances inside is very large, and those radioactive substances cannot be diluted, and can only be evolved through special techniques.
About 1.28 million tons of potentially nuclear-contaminated seawater was injected into the anti-rolling tanks of passing ships in the offshore waters of the six counties and cities surrounding Fukushima, and was discharged after reaching South Korean waters. The report pointed out that seawater near Fukushima, Japan, is flowing into the Korean Basin without any control. After the ship is unloaded, seawater, also known as balancing water, is injected into the anti-rolling tanks in order to keep the reduced weight of the ship balanced. But the problem is that after the balanced water was injected into the waters near Fukushima, these ships entered South Korea, and the balanced water that was likely to be contaminated by nuclear weapons would be discharged into South Korean waters.
The balance water injected from the sea areas of 6 prefectures near Fukushima and discharged into Korean waters is estimated to be about 1.28 million tons. The balance water injected into the offshore waters of Fukushima, which is most likely to be contaminated by nuclear contamination, is estimated to be about 6,703 tons.
Currently, South Korea prohibits the import of aquatic products from the waters near Fukushima, but seawater from this area flows into South Korea without control.
Last year, a Japanese government working group reviewed Fukushima’s sewage disposal methods and concluded that the impact of discharge into the ocean and into the atmosphere would be “short-lasting.” The chairman of the Japan Atomic Energy Regulatory Commission believes that discharging into the sea is the "only way" to deal with Fukushima sewage. Many people and fishery associations in Japan immediately spoke out and strongly opposed the discharge of radioactive sewage into the sea.
If Japan is revealed to have discharged sewage into the Pacific Ocean, it will inevitably trigger strong condemnation from South Korea. At the same time, the Pacific coastal countries that may be affected by nuclear sewage should also be aware of the seriousness of nuclear pollution and seek transnational cooperation to deal with pollution.
Total solar radiation refers to the cumulative value of solar radiation on the horizontal surface within a specific period of time. Commonly used statistical values include daily total, monthly total, and annual total.
The middle of the basin is low and the surrounding sides are high. The water vapor in the basin is difficult to disperse. It is cloudy and foggy in rainy weather, which strongly weakens solar radiation. Very little solar radiation reaches the ground, and the lighting conditions are poor. In addition, the length of sunshine will also affect the intensity of solar radiation. In addition to the cloudy and sunny weather, which will affect the length of sunshine, the length of day and night will also affect the length of light. For example, in the summer season, the farther north our country is, the longer the day will be, and the length of light will be longer. The longer it is, the more solar radiation there is.
More than 70 years have passed, and the radiation levels in Hiroshima and Nagasaki, Japan, have dropped to normal levels. The radiation value in Hiroshima is about 0.3 microsieverts/hour, with an annual average of 2.64 millisieverts, and the radiation value in Nagasaki is an annual average of 0.33 millisieverts.
Cosmic radiation refers to cosmic radio noise, which is interstellar natural radiation in the radio frequency part of the electromagnetic spectrum. Karl Jansky first discovered this radiation in 1932 when he was studying the direction of arrival of 20.5 megacycles/second lightning.
The American astrophysics research team announced at the 213th Annual Meeting of the American Astronomical Society on the 8th that the cosmic radio signal data they collected showed that the intensity of cosmic radio noise was 6 times higher than originally expected. This discovery surprised them and surprise.
100 mSv. When the radiation dose is less than 100 millisieverts, the rays are not harmful to the human body. my country's current basic dose limit for radiation is 1 millisievert per year.
In fact, we have been living in various types of radiation. But we don’t need to worry too much, because the amount of radiation generated by normal production, life and work is very small, far below the lower limit of the safety range of radiation values.
1. Relatively low. 2. This is because the Tokyo area is far away from the Fukushima Nuclear Power Plant accident, and the spread of radioactive materials is subject to certain restrictions, resulting in a low radiation dose. 3. In addition, the Tokyo City Government has also taken a series of protective measures, including monitoring radiation levels and cleaning up contaminated soil and buildings, to further reduce radiation risks. Therefore, it is relatively low and the health risk to residents is also small.
携帯電話の放射線の量は電磁放射線測定器によって測定され、この機器は携帯電話の放射線の強度や周波数などのパラメータを検出できます。携帯電話の放射線を測定する方法は次のとおりです。
専門的な機器を使用する: 携帯電話の放射線を測定するために、これらの機器は通常、高い精度と感度を備え、非常に微量の電磁放射線を検出できます。携帯電話アプリを使用する: 携帯電話からの放射線の量を測定できる携帯電話アプリも市販されています。これらのアプリは通常、電話自体のセンサーを使用して電磁放射線のレベルを検出します。ただし、これらのアプリケーションは専門的な機器ほど正確ではない可能性があることに注意することが重要です。放射線検出カードを使用する: 放射線検出カードは、携帯電話に取り付けて、携帯電話から発生する電磁放射線の量を検出するために使用できるポータブル電磁放射線測定器です。この方法はシンプルで簡単ですが、専門的な機器ほど正確ではない可能性があります。携帯電話の放射線の測定結果は、携帯電話が使用するネットワークの種類、携帯電話のモデルと場所、その他の要因などの要因によって影響を受ける可能性があることに注意してください。したがって、携帯電話の放射線を測定する場合は、より正確な結果を得るために、適切な方法を選択し、必要に応じて複数の測定を実行する必要があります。同時に、携帯電話の放射線が人体に及ぼす影響を軽減するために、携帯電話の合理的な使用にも注意を払う必要があります。
