Record 1 2013-09-19

English

Subject field(s)
  • Air Conditioning and Heating
CONT

The primary function of an air handling system for any type of clean room is to control the level of airborne contaminant particles by constantly filtering and recirculating the air. The arrangement of a system depends on whether it is to be a conventional clean room, unidirectional vertical or horizontal flow clean room. In the basic form, however, it consists of a fan, ducting for inlet and exhaust air and an air filtration system.

CONT

Because the façades are not airtight, building occupants often block up the fresh-air ducts, thereby interfering with the air circulation system.

English

Subject field(s)
  • Electromagnetic Radiation
  • Atomic Physics
  • Mining Wastes

Radon is regarded as the controlling contaminant for airborne releases. This means that, if radon control levels are met, dust emissions and gamma fields will be within acceptable levels automatically.

French

Domaine(s)
  • Rayonnements électromagnétiques
  • Physique atomique
  • Déchets miniers
  • Tiroir - Commission canadienne de sûreté nucléaire
CONT

Le radon est considéré comme étant la substance contaminante de contrôle pour ce qui est des rejets dans l'air. Ceci signifie que si les niveaux de contrôle du radon sont respectés, les émissions de poussière et les champs gamma sont nécessairement à des niveaux acceptables.
