Why does the Act provide for the secretary to declare certain materials and apparatus not to be radiation sources?
There may be material or apparatus that would otherwise meet the definitions of radiation sources in the Act even though it is not of regulatory concern because it did not pose a significant risk to the health or safety of any person or the safety of the environment. It is therefore important that there is a mechanism to declare a material or an apparatus not to be a radiation source to ensure that regulatory effort is spent on other materials or apparatus that are of regulatory concern.
