Quick Answer
Decontamination techniques after radiation exposure involve immediate removal of contaminated clothing, washing with soap and water, and the use of potassium iodide (KI) tablets to block radioactive iodine uptake. This is followed by thorough showering and washing of all body surfaces. Timing is crucial to minimize radiation exposure.
Removing Contaminated Clothing
Upon exposure, remove contaminated clothing and gear, taking care not to touch the affected area with your bare hands. Place the clothing in a sealed bag or container to prevent further contamination. If the clothing is heavily contaminated, use a brush or cloth to remove any visible radioactive particles.
Decontamination Procedures
For washing, use soap and lukewarm water, focusing on areas with visible contamination or radiation exposure. For the face, use a gentle soap and lukewarm water. For the rest of the body, use a soap specifically designed for decontamination and warm water. Wash each body surface for 15-20 minutes to ensure removal of radioactive particles. Rinse thoroughly with clean water.
KI Tablets and Shelter
Take KI tablets according to the recommended dose (typically 1 tablet per 24 hours) to block radioactive iodine uptake. After decontamination, find or create a suitable shelter with a minimum of 1 meter of distance from the radioactive source and ideally 1-2 meters of additional shielding (such as earth or water). This will reduce radiation exposure and provide a safer environment for recovery.
