Food and Drinking Water Safety in a Radiation Emergency | Radiation Emergencies | NCEH (2024)

Eat food in sealed containers (cans, bottles, boxes, etc). Unspoiled food in your refrigerator or freezer is also safe to eat. Food in a pantry or drawer away from radioactive material is safe to eat.

  • Wipe off food containers with a damp cloth or clean towel before opening them. Put the used cloth or towel in a plastic bag or other sealable container and place the bag in an out-of-the-way place, away from other people and pets.
  • Wipe off counters, places, pots, and utensils with a damp cloth or clean towel before using them. Put the used cloth or towel in a plastic bag or other sealable container and place the bag in an out-of-the-way place, away from other people and pets.
  • Do not pick or eat food from your garden until emergency officials determine it is safe to do so.

Food Safety

In the event of a radiation emergency, eat food in sealed containers(cans, bottles, boxes, etc.). Unspoiled food in your refrigerator or freezer is also safe to eat. Food in a pantry or drawer away from radioactive material is safe to eat. Food in containers from the outside that have been wiped off is safe to eat.

  • Wipe off counters, plates, pots, and utensils with a damp cloth or clean towel before using them. Put the used cloth or towel in a plastic bag or other sealable container and place the bag in an out-of-the-way place, away from other people and pets. Wash your hands after cleaning.

  • Do not pick or eat food from your garden until emergency officials determine it is safe to do so.

Pet Food Safety

  • Just like people’s food, pet food in sealed containers (cans, bottles, boxes) will be safe for animals to eat. Food in containers from the outside that have been wiped off is safe to eat.
  • Wipe off pet bowls, dishes, and mats with a damp cloth or clean towel before using them. Put the used cloth or towel in a plastic bag or other sealable container and place the bag in an out-of-the-way place, away from other people and pets. Wash your hands after cleaning.

Water Safety

Public health or emergency management agencies will test drinking water supplies to make sure they are safe. Until those results are available,bottled water is the only water that is free of contamination.

Boiling tap water does not get rid of radioactive material. You should have bottled water in your emergency supplies.

  • You can drink water, juices, or other drinks in sealed containers. Drinks in your refrigerator or freezer are also safe to drink. The package protects the liquid inside from radioactive material.
  • If you think the container or package may have radioactive material on the outside, use a damp cloth or clean towel to wipe it off before opening it. Put the used cloth or towel in a plastic bag or other sealable container and place the bag in an out-of-the-way place, away from other people and pets. Wash your hands after cleaning.
  • Water in other containers in your home, such as a toilet tank (not bowl) or hot water heater will also be free of radioactive material.
  • If those water sources are not available, then tap water should be used to stay hydrated. You can still use tap or well water for cleaning yourself and your food.

Even if the tap water is contaminated, you can still use it for decontamination.

Any radioactive material that gets into surface water or ground water sources will be diluted to very low levels by the water and will be safe to use for washing skin, hair, and clothing.

While water is being tested for contamination, public health officials may recommend that you drink bottled water instead of tap water.

Medication Safety

Continue taking your medication. Medicine already inside or medicine in containers from the outside that have been wiped off is safe to consume.

Food in a pantry or drawer away from radioactive material is safe to eat. Food in containers from the outside that have been wiped off is safe to eat.

How can we protect food and water from radiation? ›

It is safe to eat food in sealed containers that were outside as long as you wipe off the container with a damp towel or cloth before using. Seal these towels or cleaning cloths in a plastic bag and place them away from people and pets. Unsealed foods from outside may be contaminated with radioactive material.

What is the emergency response to radiation exposure? ›

In a radiation emergency:

Get inside a building and take shelter for at least 24 hours. Stay inside to reduce your exposure to radiation. Stay tuned for important information about how to keep you and your family safe.

What are the three steps you should take to protect yourself in a radiation emergency? ›

If you are indoors during a radiation emergency:
  1. Stay inside. Close and lock all windows and doors. Go to the basem*nt or the middle of the building. ...
  2. If possible, turn off fans, air conditioners, and forced-air heating units that bring air in from the outside. Close fireplace dampers.

What is the protocol for radiation emergencies? ›

If you are outside or in a car when a radiation emergency occurs, get inside a building and take shelter as soon as you can. The walls of your home can block much of the harmful radiation. It is important to stay inside until officials provide instructions or say it is safe to go outside.

How is radiation used in food safety? ›

The irradiation process happens after a food is produced and packaged. Food enters a chamber where it is exposed to a specific amount of radiation. The radiation penetrates the food and kills germs or prevents them from multiplying, and it does not linger in the food.

How does radiation affect drinking water? ›

Different doses of radiation cause different health effects. Drinking water that has radionuclides in it puts you in contact with very low doses of radiation every day. You have a higher risk of getting cancer if you drink water with radionuclides in it every day for many years.

What is an example of a radiation emergency? ›

A nuclear power plant accident, nuclear explosion or a dirty bomb are examples of radiation emergencies. Unintentional acts, or radiation accidents, can include: Nuclear Power Plant Accident – An accident at a nuclear power plant could release radioactive material into the air or water around a nuclear power plant.

What are the different types of radiation emergencies? ›

These include:
  • Spills or releases of radioactive materials (e.g., radionuclides or radioactive isotopes) from facilities where they are used for research or medical procedures.
  • Transportation incidents involving radioactive materials.
  • Medical procedures involving radioactive materials, such as radiopharmaceuticals.

What are the three major radiation safety practices? ›

This principle means that even if it is a small dose, if receiving that dose has no direct benefit, you should try to avoid it. To do this, you can use three basic protective measures in radiation safety: time, distance, and shielding.

What measures need to be taken to protect yourself from radiation? ›

Time, Distance and Shielding

Distance: Just as the heat from a fire reduces as you move further away, the dose of radiation decreases dramatically as you increase your distance from the source. Shielding: Barriers of lead, concrete, or water provide protection from penetrating gamma rays.

What are the golden rules of radiation protection? ›

Distance yourself appropriately from sources of radiation. Use appropriate shielding for the type of radiation. Contain radioactive materials within defined work areas. Wear appropriate protective clothing and dosimeters.

What are the 4 R's of radiation treatment? ›

In general, success or failure of standard clinical radiation treatment is determined by the 4 R's of radiobiology: repair of DNA damage, redistribution of cells in the cell cycle, repopulation, and reoxygenation of hypoxic tumor areas.

How can we reduce radiation in water? ›

Unfortunately, there is no simple answer for removing radiation from the water. In many cases, a combination of treatment methods, including carbon filtration, ion-exchange water softening, and reverse osmosis, is most effective.

How can we protect from radiation contamination? ›

Distance: Just as the heat from a fire reduces as you move further away, the dose of radiation decreases dramatically as you increase your distance from the source. Shielding: Barriers of lead, concrete, or water provide protection from penetrating gamma rays.

How do you treat water for radiation? ›

To reduce the risk of radioactive materials in contaminated water, water is first treated with cesium/strontium filtering equipment to remove most of the contamination. It is then treated in a multi-nuclide removal facility (ALPS), thereby removing most of the remaining radioactive materials except for tritium.

How can we make water less radioactive? ›

This is why we must have a home water filtration system in place to get rid of the radioactive substances from our home water supply. The Environmental Protection Agency recommends the use of reverse osmosis technology to eliminate all types of potential radioactive substances in water.
