What is fixed contamination?

Fixed contamination refers to radioactive material that adheres strongly to surfaces and cannot be easily removed through standard decontamination methods. This type of contamination occurs when radioactive particles become embedded in a surface, such as clothing, equipment, or structural materials, often resulting from processes like spills or the degradation of radioactive sources.

Fixed contamination poses a significant challenge because it remains in place over time, continuing to emit radiation and potentially exposing individuals who come into contact with the contaminated surface. Proper safety protocols are crucial for managing areas with fixed contamination to minimize radiation exposure risks. This characteristic distinguishes it from other types of contamination that may be more easily cleaned or removed.
