Monitoring of radioactive substances in food in China and its challenges

Monitoring data of radionuclides in food is a valuable data source for public health risk assessment. Since 2012, the monitoring of radioactive substances in food in China has been continuously advancing. Continuous monitoring can improve early warning and control capabilities, and provide a scientific basis for food safety risk assessment under normal conditions and emergencies. This article summarizes the current radioactivity measurement standards of China in environment and food, introduces the current status of radioactive substances monitoring in food, discusses issues worthy of attention, and summarizes the challenges and prospects of food radioactive substance monitoring, looking forward to providing scientific guidance for future research.
