In Austria we have a recommendation of the Austrian Radiation Protection
Commission, that the level of radon in indoor air during normal occupancy
should not exceed 400 Bq/m3 in existing houses and new houses should be
constructed in such a way that 200 Bq/m3 will not be exceeded. 

This is no compulsary limit, but only a recommendation, which cannot be
enforced. In Austria we have certain areas, in which we have a relative
high percentage of homes, in which the 400 Bq/m3 are exceeded and even
values of several thousand Bq/m3 occur. The maximum was found in a Tyrolean
village with about 80 000 Bq/m3. 

In the European Union there exists a recommendation as the Austrian one,
but I run my e-mails from at home and my papers are at my office. If you do
not get information about the EU from others, please return to me, I will
look it up and also find the source on the internet for you to check.

Best regards,

Franz
