Dalian Customs in mainland China said that an alarm sounded when a passenger passed through the radiation monitoring gate. He was carrying a bag of “health stones”, and the radiation exceeded the standard by 1,050 times. The radioactive substance thorium-232 in it was also a carcinogen. This made netizens say, “It’s so miserable to be on the same flight.”
According to “Jiupai News”, Dalian Customs stated on the 22nd that Dalian Zhoushuizi Airport Customs discovered that an inbound passenger passed through the nuclear radiation monitoring gate and the alarm sounded. He was carrying a “health stone” and the radiation level reached 105 microsieverts per hour. , the radiation exceeded the standard by 1050 times. The results of the instrumental analysis were released, and it was found that the health stone contained the radioactive substance thorium-232. Thorium-232 was once listed as a Category 1 carcinogen by the World Health Organization’s Cancer Research Agency.
After this article was exposed, netizens left messages such as “It was so tragic on the same flight”, “People on the same plane will also be harmed by nuclear radiation! It doesn’t say which country they got the harmful goods from”, “What kind of health stone has this effect?” , they didn’t even need medicine, they just sent the person away”, “Let him eat”, “Spy”, “How did you bring it on the plane? You have to go through security before getting on the plane”.
It is understood that thorium-232 easily absorbs neutrons and becomes uranium-233, and uranium-233 is prone to nuclear fission. Thorium dioxide suspension containing thorium-232 was once used as a diagnostic contrast agent, commonly known as thorium contrast agent, but because 65% of patients who received thorium contrast agents developed liver tumors, so they have been abandoned. Thorium-232 is also listed as a carcinogen.
In addition, this is not the first similar incident in mainland China. In July, Shenyang Customs discovered that passengers brought 15 health stone necklaces into the country. The radiation dose was about 46 microsieverts per hour, and the radiation exceeded the standard by 468 times. The health stones were analyzed and found to contain the radioactive substance barium-133. and thorium-232.
