A working group of experts according to Article 31 of the Euratom Treaty prepared a draft ``Council Directive`` for handling radioactive materials. Particularly for naturally occurring radioactive materials this new Directive allegedly signifies a considerable tightening of the limits below which radioactivity is allowed to be present in the environment. The Dutch Ministry of Housing, Physical Planning and Environment commissioned an inquiry to be held among a limited number of companies in separate branches of the non-nuclear industries in the Netherlands to inventories the possible consequences for these companies if the published draft Directive were to be implemented unabridged in its present form. This paper provides an analysis of the inquiry. It shows that after implementation of the Directive in the Dutch legal system a number of companies will be under official duty to report or obtain licenses under the Nuclear Energy Act without advantages for radiological protection. For these companies this means a great deal of administrative work and considerable additional costs. If the proposed exemption levels for the naturally occurring radioactive materials, are liberalized by a factor of ten, the problems will be much smaller and controllable.
