Behavior and effect of the population in the outbreak of nuclear destruction are largely dependent on where it was at the time of a nuclear explosion: in shelters (shelters) or outside them.

It should be just carefully follow the rules of stay in them, to comply strictly with the requirements of commanders (senior) and other up to 3 days, in the infected area with a level of radiation 240 R / h and above this time is 3 days or more. After this period of shelters (shelters) can go into the living room. During the next 1 – 4 days (depending on the level radiation in the areas of infection) of these facilities can go outside from time to time, but no more than 3 – 4 hours a day. In dry and windy weather, when possible dust formation, when leaving the premises should be used personal respiratory protection.
