Which process aims to reduce contamination to a level that is As Low As Reasonably Achievable (ALARA)?

The process that aims to reduce contamination to a level that is As Low As Reasonably Achievable (ALARA) is best represented by Technical Decontamination. This approach involves more detailed and thorough decontamination procedures, which are designed to minimize exposure to harmful contaminants while also considering operational feasibility and safety.

Technical Decontamination typically includes the use of specialized techniques and equipment to ensure that the level of contamination is not only reduced but managed in a way that is effective and safe for both the personnel involved and the environment. By applying this process, responders can control contamination effectively, thereby reducing health risks associated with exposure to hazardous materials.

Other options, such as Gross Decontamination, are primarily intended for initial, rapid removal of contaminants, while Mass Decontamination is focused on a large number of people but may not achieve the same level of thoroughness as Technical Decontamination. Emergency Decontamination generally refers to urgent measures taken to remove contaminants in life-threatening situations, which may not always achieve the ALARA principle due to the need for immediacy. Thus, Technical Decontamination stands out as the correct choice for achieving contamination reduction that meets the ALARA standard.
