How to avoid nuclear radiation in emergency?

According to the website of the National Atomic Energy Agency, in order to avoid or reduce the dose of nuclear radiation that workers and the public may accept in an emergency, certain emergency protective measures can be taken, such as concealment, evacuation, iodine protection, access control, food and drinking water control, Pollution, temporary relocation, permanent resettlement, etc.

When the accident has or may lead to the release of radioactive isotopes of iodine, iodine protection can also be implemented, that is, taking a compound containing non-radioactive iodine to reduce the thyroid exposure dose. The risk of negative effects from taking stable iodine is very small for a single dose, but it increases with the amount taken.
