Dear Moshe,
There is no doubt that the IAEA BSS and the ICRP 60 are reasonable and that
ideas have been found their way to the EU directive 29/96. But the directive
has to be implemented into national law and the member states have a certain
freedom to set their own limits - and therefore also own clearance levels. I
have made a survey on the implementation of the directive into national
legislation and I found, that member states have set in many cases different
values, especially with respect to naturally occurring radionuclides. The
"10 microSv" concept seems not to be widely accepted and most member states
rather adhere to the 1 mSv concept. (Btw: How do you measure 10 microSv per
year additional dose?????) Some countries - including Spain and Austria -
have still not implemented the directive into national law.
Nevertheless it is legally not acceptable for persons and companies to refer
to either the IAEA BSS or ICRP - they have to obey their state legislation.
Both the BSS and ICRP recommendations are - well, recommendations and
nothing more.
Best regards,
Franz
