In what way does environmental exposure affect film badges?

Film badges are sensitive devices used to measure an individual's exposure to ionizing radiation. Their effectiveness can be impacted by various environmental factors such as humidity, temperature, and exposure to light. These elements can cause the film emulsion to deteriorate or become fogged, which may result in inaccurate dosage readings. When the film is exposed to conditions outside of the controlled testing environment—such as high humidity or extreme temperatures—the film may register additional exposure that does not correlate with actual radiation exposure. This is why they can become less effective as reliable dosimeters if not stored and handled properly.

Understanding the effects of environmental exposure on film badges is critical for ensuring accurate readings and maintaining safety standards for individuals working in radiation environments. Proper storage conditions are essential for ensuring that the dosimeters provide precise and trustworthy results.
