General conditions for monitoring

Monitoring is not required at the source or in the environment for sources that give rise to exposures that are excluded from regulatory control because their magnitude or likelihood is essentially unamenable to control through the requirements of the BSS [2]. A relevant example in the context of this 

Practices and sources can be exempted or materials cleared from the requirements for regulatory control if the associated radiation risks to individuals and populations are low enough to be of no regulatory concern and the exempted practices or sources are inherently safe [2]. For exempted practices and sources or cleared materials that include discharges, there is no requirement for monitoring. An example of exemption is a small laboratory that utilizes amounts of radionuclides for which either the total activity of a given radionuclide or the activity concentration is below the exemption level [2]. 

Intervention situations requiring a response in order to reduce or avert exposures can be emergency exposure situations or situations of chronic (prolonged) exposure. Protective and remedial actions are not normally likely to be necessary unless intervention levels or action levels are or may be exceeded. The initial input for decision making with regard to protective or
