A radiation detector on an e-commerce platform is an instrument used to measure and monitor the level of nuclear radiation in the surrounding environment. It can determine whether food, cosmetics and other products are contaminated by nuclear radiation by measuring the radiation level around the radiation source. The principle of nuclear radiation detector is mainly to use a radiation detector to measure radiation and convert the measurement results into a digital or graphical display so that users can understand the radiation level.

There are many types and brands of radiation detectors on e-commerce platforms, and the prices are also different. In general, radiation detectors can be divided into two main categories: Geiger counters and scintillation counters. Geiger counter is a counting instrument specializing in detecting the intensity of ionizing radiation, by an inflated tube or chamber as a probe, when the voltage applied to the probe reaches a certain range, the ray in the tube for each ionization to produce a pair of ions, can amplify to produce an electrical pulse of the same size and is connected to the electronic device recorded, so the number of rays per unit time can be measured.
Geiger counters detect α particles, β particles, and gamma rays. A scintillation counter is an instrument that uses the flash phenomenon generated when radioactive material interacts with a substance to detect radioactive material, and consists of a scintillator, a photomultiplier tube, and a signal processing circuit. Scintillator is a substance that can convert incident particles or photons into visible or ultraviolet light, photomultiplier tube is a device that can convert incident photons into electrical signals, and signal processing circuit is a circuit that can amplify, shape, filter and other electrical signals. Scintillation counters detect α particles, β particles, gamma rays, and neutrons.
Doesn't that sound great??
I analyzed for you a lot of rush to buy nuclear radiation detectors on e-commerce platforms after Japan's nuclear wastewater was discharged into the sea, and explained whether ordinary people need to rush to buy nuclear radiation detectors, and whether such instruments are useful in life. Please see:
After Japan's nuclear wastewater was discharged into the sea, there were many rush to buy nuclear radiation detectors on some e-commerce platforms, which may be due to the following reasons:
- Some consumers lack scientific understanding of the impact of Japan's nuclear wastewater discharge into the sea, and are worried that nuclear radiation will cause harm to China's environment and human health, so they want to buy a radiation detector to monitor the radiation level around them for peace of mind.

- Some businesses take advantage of consumers' panic to exaggerate or falsely advertise the function and necessity of nuclear radiation detectors to induce consumers to buy, thereby obtaining profits.
- Some consumers, out of curiosity or interest, want to buy a radiation detector to explore and learn about the knowledge and phenomenon of nuclear radiation, or as a novel toy.

However, the general public does not need to snap up radiation detectors because:
- According to the analysis and assessment of authoritative institutions and experts, the impact of Japan's nuclear wastewater discharge into the sea on China's environment and human health is negligible, and China has a perfect monitoring and early warning system that can detect and respond to any possible abnormal situation in a timely manner.
- A nuclear radiation detector is a professional scientific instrument that requires proper use and calibration to obtain accurate and reliable data. Many so-called nuclear radiation detectors on the market may be products of unqualified quality or imperfect function, which cannot truly reflect the actual situation of nuclear radiation, and may even cause misleading and panic.
- A radiation detector is not intended to be an entertainment or educational item, it involves complex physical principles and technical details that require specialized knowledge and skills to understand and operate. If it is not necessary, it is not recommended that ordinary people buy and use it at will.
In summary, in life, ordinary people do not need to rush to buy nuclear radiation detectors, nor will they get any practical benefits from them. Instead, we should trust science and authority, remain rational and calm, and not blindly follow or be misled.
