Speaking of the top issues recently, Japan's discharge of Fukushima radioactive water inevitably takes the very lead.
The discharge has already aroused wild attention at home and abroad, and has as well triggered a series of relevant heated issues. For example, the pollution of seawater raised people's concerns about the source of salt production. People's fear of losing salt or increasing salt prices eventually transformed into a rush for salt in the markets nationally.
Sometimes, the prudence of we Chinese people is almost to the point of being unfounded. As for some examples, people recently have set off a mad scramble for nuclear radiation detectors.
"Oh, it would be super terrifying if the seafood I just bought kept some nuclear staff remains!"
"Then why not move up and buy a nuclear radiation detector for testing? Cherish life, starting from yourself!"
Recently, if you tap "nuclear radiation detector" in the sales platform, you will find that the "growth rate of this week" for this kind of product appears to be 232%. These kinds of products claim to be available to test Japanese food, cosmetics, seafood, marble, etc. Plenty of online sales customer service would say that the product is not in stock, or that the recent order volume is so big that it would take a long time for delivery.
Nuclear radiation detector explodes the sales platforms. Is it truthfully as useful as claimed?
Zhang Yongqing, a professor at the School of Environment and Energy at the South China University of Technology, explained that radioactivity measurement has so many complicated steps to deal with, so it is far from enough to just have instruments for detection. Steps, for example, include sample collection, sample pre-treatment, the establishment of measurement environment and so on. In addition, the detection steps also vary with different substances in the sample. What's more, in such detection of chemical substances, so many attention points should be taken into attention.
To sum up, for ordinary people without professional knowledge, there is totally no need to detect nuclear radiation with some ordinary detection instruments. We shall keep our reasons when faced with such issues, avoiding excessive panic.
