Japan postpones decision to discharge Fukushima nuclear wastewater into the sea on October 24, 2020
Japan’s nuclear wastewater reserves are about to reach their limit on March 4, 2021
On April 9, 2021, the Japanese government basically decided to discharge the Fukushima nuclear wastewater into the sea
On April 13, 2021, the United States supported Japan’s decision to release Fukushima sewage into the sea.
On April 19, 2021, Japan’s TEPCO will begin submitting a nuclear-contaminated water discharge schedule to the government next month.
On April 19, 2021, radioactive fish exceeding the standard reappeared in the waters of Fukushima, Japan.
Japan’s decision to discharge more than one million tons of nuclear wastewater into the sea has triggered strong opposition from the Japanese people, South Korea, Russia, the Philippines, and China. Just imagine, once the ocean, which accounts for 71.8% of the earth’s surface area, is polluted, to what extent will the earth on which human beings depend for survival be damaged?
How much nuclear wastewater is there in Japan?
According to reports, Japan’s Fukushima Daiichi Nuclear Power Plant has more than 1.23 million tons of nuclear wastewater. If Japan discharges such a large amount of nuclear wastewater into the ocean, it is expected to spread to the entire Pacific within 57 days!
In this regard, my country’s Ministry of Foreign Affairs spokesperson Zhao Lijian said: “The Fukushima nuclear accident in Japan is one of the most serious nuclear accidents in the world to date. The accident caused the leakage of a large amount of radioactive materials and has had far-reaching consequences for the marine environment, food safety and human health. Influence”!
Why did Japan decide to discharge nuclear wastewater into the ocean?
The assessment report of the International Atomic Energy Agency expert team pointed out that in addition to the radioactive substance tritium, the existing treated wastewater still contains other radioactive elements, but the Japanese government has rarely responded publicly to this. In fact, since 2013, the Japanese government has proposed five options for treating nuclear wastewater: injection into the ground, discharge into the ocean, steam release, electrolysis treatment, and solidification and burial underground.
Among these five options, discharging nuclear contaminated water into the ocean is the lowest cost, estimated to cost 1.7 to 3.4 billion yen, or about 102 million to 203 million yuan, while the most expensive option is to solidify it The cost of burying it underground is estimated to be dozens or even hundreds of times that of discharging it into the sea. Therefore, Japan selfishly chose the lowest-cost solution, regardless of the marine environment, food safety, and the health of all mankind!
How much impact does nuclear wastewater have on humans?
How much impact does nuclear wastewater have on humans? Taro Aso, Japan’s Deputy Prime Minister and Minister of Finance, told reporters: “According to scientific evidence, this should have been done a long time ago,” and insisted that “there is nothing wrong with drinking that water.” Such remarks aroused criticism from many Japanese netizens. Some people shouted: “Aso-san, drink one in front of everyone!”
In fact, most radioactive elements in nuclear wastewater can be filtered, but some of them are difficult to process, such as carbon 14. Its radioactivity can last for 5,730 years. Once discharged into the sea, it will cause harm to humans for thousands of years to come. Potentially toxic. In addition, tritium, a radioactive element, can not only kill cells, but also induce genetic mutations and lead to biological deformities. Therefore, the occurrence of species mutations in the sea is by no means sensational, and even the appearance of a real-life version of Godzilla is not unusual.
If humans are exposed to nuclear radiation, cells will not be able to divide and replicate normally, white blood cells will decrease sharply, and the human body will lose immunity. This means that small wounds cannot be healed, but will become larger and larger until the skin falls off, blood and body fluids It seeps out, and the person is awake during the whole process! This is just the consequence of being exposed to radioactive material, let alone drinking “that water”! If Japan does this, it will be boycotted by all mankind!
Today is the 52nd World Earth Day. Protecting the earth, protecting the environment, and protecting the ocean are the unshirkable responsibilities of mankind. Protecting Mother Earth is not only a matter of “voice”, but also a matter of “deed”. So when it comes to nuclear wastewater entering the sea In an unprecedented crisis, what can we do?
I have also thought about this matter. If Japan really discharges nuclear wastewater into the ocean, we can use Internet of Things technology to provide wireless data transmission support for ocean monitoring.
How to use the Internet of Things to monitor the marine environment?
In ocean monitoring, according to different carriers, they can be divided into marine instruments, submersible instruments, buoy instruments, shore station instruments, aircraft and satellite instruments. These instruments carry ocean temperature measuring instruments, salt measuring instruments, wave measuring instruments, Flow measuring instruments, etc.
We can put measuring instruments for radioactive elements such as tritium, cesium-134, cesium-137, iodine-129, strontium-90, cobalt-60 and other radioactive elements into the sea to monitor pollution sources. Due to the special environment of the ocean, data can only be transmitted through wireless communication technology. Therefore, after the measuring instrument measures the data, it needs to be transmitted remotely to the data center.
After various measuring instruments send data to the E22 wireless communication device through UART, E22-A transmits the data to E22-B, which is about 10km away, through a new generation of LoRa spread spectrum technology. If the distance is too far, you can increase the power or add a Relay equipment; E22-B transmits data to the data center through UART. After the data is processed, the data can be displayed on the monitoring center in real time through intuitive methods such as charts, change curves, maps, etc. for data personnel to view and provide early warning.
Feature display
The wireless communication equipment used in the case is Ebyte E22-S1C series products, which have many advantages such as long transmission distance, stable data, and low power consumption.
Long transmission distance: The E22-S1C series products adopt a new generation of LoRa spread spectrum technology, with longer transmission distance (22dBm: 5.5KM; 30dBm: 10KM), lower power consumption (2uA), and smaller size.
Data is more stable: Based on the new LoRa spread spectrum technology, not only the transmission distance is greatly increased, but the anti-interference ability is more than doubled, ensuring the stability of the data.
Lower power consumption: E22-S1C series LoRa module sleep current is as low as 2uA, and also supports air wake-up function.
Case advantages
Low cost: achieve stable wireless communication network at lower cost;
The networking is simple and convenient: only simple networking is required to implement the application, and the networking is more flexible;
Low power consumption: the sleep current is as low as 2uA, and it also supports wake-up over the air, making the application more convenient;
Customizable: Specific functions can be customized and developed according to the actual needs of customers;
Rich frequency bands: supports 410.125~493.125MHz and 850.125~930.125MHz frequency bands.Keywords: 4-channel analog acquisition module
