Provide your animals stored feed such as hay, silage and bagged grain. Whenever possible, animals should be provided water drawn from wells. Open sources such as ponds, creeks, or rivers should be avoided if possible. These protective measures will minimize the amount of radioactive material available to your animals. Since evacuation of farm animals will not normally be possible after a nuclear accident, sheltering and the use of stored feed and well water are the most effective means of limiting contamination.
Poultry are more resistant to radioactive contamination than other farm animals.
Since most are raised in confined facilities and receive stored feed and well water, they can be sheltered in their existing structures. If your poultry animals are normally kept outdoors, they should be brought inside if possible. Egg shells provide natural protection from contamination. Generally, eggs will be safe to eat after the shells are washed to remove surface contaminants. If animals have been exposed to radioactive particles carried by winds or rain from the accident site, they should be washed with uncontaminated water before being brought into a shelter.
