What nuclear radiation protection measures should be taken at different stages?

According to the China Center for Disease Control, after a nuclear and radiation emergency, different protective measures can be taken at different stages. Within 1 to 2 days of the incident, the protective measures available to personnel are: concealment, respiratory tract protection, taking stable iodine, evacuation, and controlling the entrance and exit routes. Among them, respiratory protection is the action of covering your nose with a dry or wet towel to prevent or reduce the inhalation of radionuclides. Taking stable iodine can prevent or reduce the deposition of radioactive iodine in the plume into the thyroid after entering the body.

In the mid-stage of the incident, a considerable amount of radioactive material has been deposited on the ground. At this time, in addition to considering the suspension of respiratory protection for individuals, other early protective measures can continue to be taken. In order to avoid excessively high cumulative doses for long stays, the competent authority may adopt controlled and planned relocation of people from contaminated areas. Consideration should also be given to restricting the sales and consumption of locally produced or stored food and drinking water. According to the characteristics of the exposure route to personnel during this period, the protective measures that can be taken are: the use of stored feed in animal husbandry, the decontamination of the surface of the personnel, and the treatment of the injured and sick.

The question faced in the late stage of the accident (the recovery period) is: whether and when the normal life of the society can be restored; or whether further protective measures need to be taken. In the late period of the incident, the main route of exposure was internal exposure caused by ingestion of contaminated food and inhalation of resuspended substances. Therefore, the protective measures that can be taken include the control of import and export access, evacuation, control of food and water, use of stored feed and regional decontamination.
