Recently, the "hairy crab sounded the sound of nuclear radiation alarm", which made many citizens pay new attention to the product of "nuclear radiation detector". On September 2, upstream news reporters searched major e-commerce platforms and found that the current sales of various brands of nuclear radiation detectors are considerable, and there are many merchants with monthly sales of tens of thousands, and if a popular brand places an order now, the final payment will be paid on September 30, and the delivery will be arranged within 20 days after the final payment is paid.

On the 2nd, the reporter searched on Taobao and found that the current popularity of "nuclear radiation detector" is 5.674 million, and the search popularity increased by 232% this week, appearing on Taobao's hot search. If you arrange it according to sales, the sales of nuclear radiation detectors in multiple businesses have exceeded 10,000 units. Taking the number one merchant as an example, there are a total of 5 kinds of goods in the store, and the prices range from 68 yuan to 488 yuan. The customer service said that the "N3 professional medical grade nuclear radiation detector" sold the best at 488 yuan, and the "portable high-precision nuclear radiation detector for hot sellers" priced at 399 yuan also sold well.
Sales of other brands of radiation detectors are also considerable, and products with more than 1,000 sales recently abound. Taking a brand of nuclear radiation detector as an example, the price of three products ranges from 458-698 yuan, and thousands of units have been sold recently. The customer service said: "Our products are accurately tested and meet national standards. Whenever there is radioactive radiation in liquid or nuclear wastewater, it can be detected and the corresponding value can be displayed. ”

Upstream news reporters noticed that on the product detail page of many household nuclear radiation detectors, the core equipment of their instrument is a "high-sensitivity" Geiger Miller counting tube, which senses the intensity of ionizing radiation through an inflatable probe. Many merchants claim that the detector can measure radiation containing X-rays, beta rays, etc., and can measure food, cosmetics, seafood, ore, marble, etc. In the process of use, in addition to Ms. Xu's "hairy crab and daughter's belly" alarm oolong incident, many netizens have posted their bizarre encounters when using nuclear radiation detectors: such as issuing an alarm when approaching bananas, measuring everywhere and finally finding that the most radiation is their home, and so on.
On the 2nd, the upstream news reporter contacted Mr. Zhao (pseudonym), who works in a domestic nuclear power plant, according to him, such a household nuclear radiation detector priced at several hundred yuan, consumers are more likely to "pay IQ tax".
"Otherwise, why are the instruments in our laboratory purchased in units of 10,000 yuan?" Mr. Zhao introduced, "The current radiation environment monitoring is the method of sampling monitoring, which requires a series of complex tests such as nuclide spectrum analysis in the laboratory to determine whether the radioactive material in it exceeds the standard. ”
Regarding whether citizens need to buy nuclear radiation detectors, Zhang Yongqing, a professor at the School of Environment and Energy of South China University of Technology, previously said in an interview with CCTV that the necessity of ordinary citizens to buy radiation detectors is not strong. Because different nuclides have different measurement methods, only one instrument is not enough, but also a corresponding method.

According to media reports, Lin Boqiang, director of the China Energy Policy Research Institute at Xiamen University, also said that "testing nuclear radiation for marine products has never been done before." In fact, it's just for your own peace of mind, don't make yourself more uncomfortable. According to Oriental Satellite TV, Wang Xiaowa, a registered nuclear safety engineer at Shanghai Proton Heavy Ion Hospital, said that different radiometric measurements can be measured, but whether they can accurately reflect the dose level is debatable." Different rays are measured by a single radiation detector, which is not scientific and rigorous enough. Self-testing at home is basically not accurate enough, and needs to be sampled to the laboratory according to national standards for professional testing. ”
Recently, potassium iodide and others have also become "anti-nuclear radiation" artifacts. Image source/screenshot
Upstream news reporters found that in addition to household nuclear radiation detectors, some products claiming "radiation-proof" appeared on online social platforms and e-commerce platforms. The reporter searched for keywords such as "anti-nuclear radiation" and "nuclear radiation drug", and the results were that "iodine and potassium tablets" were the most common and best-selling, including "nuclear wastewater filter" and "anti-radiation hand string". According to Red Star News, Yang Yong, chief pharmacist of the Department of Pharmacy of Sichuan Provincial People's Hospital, said in an interview that in the instructions for taking potassium iodide drugs, there was no prevention of "radiation prevention". "It's basically useless." Yang Yong said that whether it is healthy people or people with abnormal thyroid function, taking potassium iodide without authorization will have an impact on the thyroid function of the human body.
