The GLs state, “as far as generic radiological protection of food consumers is concerned, when radionuclide levels in food do not exceed the corresponding GL, the food should be considered as safe for human consumption.” When the GLs are exceeded, national governments shall decide whether and under what circumstances the food should be distributed within their territory or jurisdiction.

如果超过指导值，应由政府决定是否以及在什么情况下在其领土或管辖范围内提供此食品。
National governments may wish to adopt different values for internal use within their own territories, where the assumptions concerning food distribution that have been made to derive the GLs may not apply, e.g., in the case of widespread radioactive contamination.
For foods that are consumed in small quantities, such as spices, that represent a small percentage of total diet and hence a small contribution to the total dose, the GLs may be increased by a factor of 10.
GLs for radionuclide levels in food can be found in the Codex General Standard for Contaminants and Toxins in Food and Feed – ( CODEX STAN 193-1995 ).

在发生放射性或核紧急情况后，可以采取哪些措施监测食品安全？
What actions can be taken to monitor the safety of food following a radiological or nuclear emergency?
In response to a radiological or nuclear emergency, the national authorities should implement monitoring of food products and restrict the consumption and distribution of some products in certain areas if the amount of radionuclides they contain exceed levels consider acceptable in local regulations, and in accordance to international standards.
