Human decontamination is the process of removing hazardous materials from the human body, including chemicals, radioactive substances, and infectious material. General principle [ edit ]
It is also a form of decontamination, and can be defined as the process whereby physical or chemical methods are used to reduce the amount of pathogenic microorganisms on a surface. [ 2 ] [ 3 ] Disinfectants can also be used to destroy microorganisms on the skin and mucous membrane, as in the medical dictionary historically the word simply ...

Items to be sterilized must first be cleaned in a separate decontamination room and inspected for effectiveness, cleanliness and damage. There are multiple methods of sterilization, and which one is used is ...
The residual radioactive contamination on the surface is significantly reduced once the strippable coating is removed. Modern strippable coatings show high decontamination efficiency and can rival traditional mechanical and chemical decontamination methods. Decontamination gels work in much the same way as other strippable coatings. The results ...
Within the sciences, the word "contamination" can take on a variety of subtle differences in meaning, whether the contaminant is a solid or a liquid, [3] as well as the variance of environment the contaminant is found to be in. [2] A contaminant may even be more abstract, as in the case of an unwanted energy source that may interfere with a process. [2]

[1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless". [2]
Dry decontamination is a relatively recent method of decontamination and is especially useful in cold weather conditions, [2] or when water is scarce or difficult to transport. Dry decontamination reduces the size and manpower requirements of the decontamination line and eliminates the need to purchase excess equipment that becomes ineffective ...
