11. In situations where the activity concentration of a specific radionuclide consistently exceeds the values specified in Tables 1 and 2, a long-term monitoring program to follow changes in the activity concentration and to evaluate the doses to consumers shall be established. This would be particularly important if the food in question is a staple food widely consumed throughout the country. Along with regular analysis of food samples, the establishment of monitoring programs shall allow providing factual public information and quickly identifying situations where further investigation, and possible actions, may need to be considered.
12. Various analytical methods for radioactivity in foods are summarized in Table 5. The measurement of activity concentration should be performed according to the approved standard methods of measurement that can be used for concluding whether the reference levels are exceeded or not.
