Regulation and enforcement procedures

Three successive phases may be identified in the orderly development of regulation and enforcement procedures. First, biological changes and possible hazards to health are identified and studied. Next, based on such studies, standards are derived and proposed. These are generally of two types, namely exposure standards (concerned with individuals who may be exposed either occupationally or in the course of everyday life) and emission standards (concerned with devices and installations which emit NIR, whether intentionally, incidentally or because they have developed a fault). The third phase is the translation of exposure and emission standards into appropriate procedures
