Decontamination (sometimes abbreviated as decon, dcon, or decontam) is the process of removing
contaminants on an object or area, including chemicals, micro-organisms or
radioactive substances. This may be achieved by
chemical reaction
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and break ...

or physical removal. It refers to specific action taken to reduce the hazard posed by such contaminants, as opposed to general
cleaning
Cleaning is the process of removing unwanted substances, such as dirt, infectious agents, and other impurities, from an object or environment. Cleaning is often performed for aesthetic, hygienic, functional, environmental, or safety purposes. ...
