N2	- At that time of publication SSR49 two exposure situations were considered, namely: practices
and interventions, with Naturally Occuring Radioactive Material (NORM) being considered as
intervention exposures but acknowledging that some natural sources can have exposures resulting from
practices. In the Ba sic Safety Standards (BSS) the exposure situations have been categorised as
planned, emergency and existing. These three situations necessitate an update of SSR No.49 since NORM fits
in the existing situation, i.e one in which the doses already exist and should be reduced. To reduce the doses
will create radioactive waste that must be either treated or stored. This scenario raises a problem of defining
the dividing line between existing and planned situations. The point of transistion from one situation to the
other needs to be clarified in order to establish the necessary controls for an existing situation whilst
providing the necessary controls needed for the planned situation. For the latter planned situation several
questions arise as to whether certain requirements can be exempted and under what circumstances. This paper
will examine what the authors consider most important in more detail with some suggestions made for further
consideration.
