Discharge of functions: mobile radioactive apparatus12
1
In the case of an activity described in paragraph 11(5), if the principal place where the apparatus mentioned in that sub-paragraph is kept when not in use is in England or Wales, functions in relation to the activity are exercisable by the appropriate agency in whose area the principal place of keeping is.
