On behalf of SEPR, a zircon processing company (fused-cast refractories for the glass industry), we would like to emphasise that the current “Draft recommendations” document is well balanced and good readable. The changes in relation to the ICRP 1991 recommendations are reasonable. We appreciate that natural sources of radiation are taken increasingly into the focus. Regarding exclusion and exemption (chapter 2.4, paragraph 42): It is not made clear whether the established and well proven Basic Safety Standards system of exclusion, exemption and clearance is intended to be modified. What is the reason not to mention the issue of clearance?
