Emergency supplies for a radiological incident—what to pack?

May 8, 2026

Quick Answer

Pack emergency supplies that include a Geiger counter, potassium iodide tablets, a radiation-resistant shelter, and non-perishable food and water for at least 72 hours. Consider a personal air purifier and a radiation suit. Don't forget a first aid kit and a communication device.

Essential Items for Radiation Exposure Prevention

When preparing for a radiological incident, it’s crucial to have the right protective gear and supplies. Potassium iodide (KI) tablets can help prevent radioactive iodine uptake in the thyroid gland. Store at least 14 tablets per person, as recommended by the World Health Organization, and follow the instructions for administration carefully. Ingest the tablets within 24 hours of exposure to radioactive iodine.

Shelter and Protective Gear

A radiation-resistant shelter or a vehicle with a radiation-proof liner can provide a safe haven. If you don’t have access to a shelter, a 6-mil (0.15 mm) thick plastic tarp or sheet can offer some protection from radiation. Wear a radiation suit rated for the expected radiation levels. A well-fitting suit with a hood and face mask can reduce exposure by 90%.

Communication and First Aid

A two-way radio or a satellite phone can help you stay in touch with family and emergency services. A first aid kit should include supplies for treating radiation exposure effects like radiation burns and thyroid damage. Don’t forget a radiation detection device like a Geiger counter to monitor the environment and avoid contaminated areas.
