What characterizes Fixed Contamination?

Fixed contamination refers to radioactive material that has adhered to surfaces or has become part of a material, making it difficult to remove by usual cleaning methods. This type of contamination is typically found in settings such as radiological facilities or areas where radioactive materials are used, where they can bond tightly with surfaces. Because of this strong adhesion, fixed contamination often requires specific decontamination techniques or procedures to properly address it.

In contrast, the other choices describe characteristics that do not apply to fixed contamination. For instance, the notion that it can be easily removed is characteristic of removable contamination, which is more loosely bound and can be washed away or wiped off. Fixed contamination can be found in various locations, including indoor spaces, and is not limited to open areas. It does not directly cause immediate sickness, as the effects depend on various factors like the type of radioactive material, exposure levels, and duration of exposure. Understanding these characteristics helps radiological workers implement appropriate safety measures and decontamination protocols.
