Tianjin Inspection and Quarantine investigated an incident
Central Radio network Tianjin April 24 news (reporter Jia Liliang correspondent Chen Fei) Recently, Tianjin East Port inspection and quarantine Bureau staff in a batch of imported waste raw materials on-site inspection, the suspected radioactive situation of the batch of goods were investigated.
This batch of goods is a batch of containers from Japan loaded with waste plastic, the goods through the inspection field warehouse door type radioactive detector, the detector issued an alarm sound, again through the alarm is still. The inspection and quarantine personnel immediately carried testing and protective equipment, transferred the goods to the supervision and quarantine area and set up warning signs, and then inspected the goods in strict accordance with the nuclear, biochemical and harmful factors monitoring procedures of China port. Portable radioactive dose-rate meter and α , β Surface contamination meter detection, determine the goods γ The highest radiation dose equivalent rate reached 0.19 microsieverts/hour, exceeding the environmental background value (0.08 microsieverts/hour) by 0.11 microsieverts/hour, but below the national limit of radioactivity exceeding the limit (the environmental background value of 0.08 microsieverts/hour plus 0.25 microsieverts/hour, that is, 0.33 microsieverts/hour).
According to the "Port nuclear, biochemical and harmful factors monitoring technical plan" of AQSIQ, the on-site inspection and quarantine personnel determined that this is a general abnormal radioactive event, which can basically rule out the suspicion of nuclear terrorist attack. After an in-depth investigation of the cargo information and consulting the relevant information, the inspection and quarantine personnel confirmed that the goods would not cause harm, and the cargo information was registered and released.
As the source of waste raw materials is more complex, radioactive events occur from time to time, once it enters the processing link will have a serious impact on the local environment and people's health. In 2015, Tianjin Inspection and Quarantine Bureau investigated 7 batches of waste raw materials with abnormal radioactivity, effectively preventing the goods with excessive radioactivity from entering China, and ensuring the national environmental security and people's health.
