If you mean dose rate limits in facilities, we don't have any.
Our limits are integrated dose for a month or an hour.
- Public aera < 1,25 mSv for a month
- Controlled area 1 < 4 mSv for a month
- Controlled area 2 < 2 mSv for an hour
- Controlled area 3 < 100 mSv for an hour and always < 100 mSv averaged for 1 second (needs some explanation here- It's for X-rays device)
- Controlled area 4 (forbidden area) > 100 mSv for an hour or > 100 mSv averaged for 1 second
French legislitation is in the course of being modified following changes in european legislation in 2013. We are still waiting for a ministerial order with something a bit more operational :)

At what level do other countries set up radiation control boundaries? 1,2, or 5 mr/hr ...(well, OK, most all the rest of the world would use 10, 20, or 50 uSv/hr), but what do others do?
