The preliminary standard applies to the examination of meat and meat products for the purpose of radioactivity measurements. Meat is defined as: red and white meat, including game. Meat products, meat products and individual organs (for example thyroid, liver and kidney) can also be sampled according to this preliminary standard. The samples can, after possible sample preparation according to NVN 5642, be used for various radioactivity measurements. The described method is suitable for accident situations, but can also be used for background monitoring. Note In the event of an accident, contamination of meat is mainly the result of food ingestion, but contaminated drinking water or inhalation can also be an important route. The main types of meat are beef, veal and pork. In meat, the levels of 134Cs and 13rCs may be particularly important, while bone seekers such as 90Sr are only absorbed to a small extent in the meat. Furthermore, nuclides can be accumulated in certain organs, for example 131l in the thyroid gland.
