Core Viewpoint - The Dalian Zhoushuizi Airport Customs recently intercepted a radioactive amulet with radiation levels exceeding safety standards, highlighting ongoing concerns regarding the importation of radioactive materials [1] Group 1: Incident Details - Customs officials detected a radiation alarm triggered by a passenger's amulet during routine checks, revealing a radiation dose of 168.6 μSv/h, which is 1686 times the background level [1] - The amulet was found to contain the radioactive isotope Thorium-232, which the passenger claimed was a gift from a friend [1] Group 2: Previous Incidents - In October of the previous year, Dandong Customs also seized a batch of radioactive natural stone jewelry, which included 34 pieces of jewelry and four packages of loose items, all containing Thorium-232, with a gamma radiation dose of 9.574 μSv/h, 63.82 times the background level [1] Group 3: Regulatory and Health Implications - Thorium-232 is classified as a Group 1 carcinogen by the International Agency for Research on Cancer, emphasizing the health risks associated with exposure [1] - Customs authorities advise travelers to be aware of the composition of overseas products to avoid carrying or mailing items with excessive nuclear radiation into the country, and they will enforce legal measures against such imports [1]

Core Viewpoint - Recent incidents at Dalian Zhoushuizi Airport customs have highlighted the risks associated with travelers carrying items containing radioactive materials, specifically thorium-232, which is classified as a Group 1 carcinogen by the World Health Organization [3][5].
