[ RadSafe ] Radiation dose rate control levels internationally

[BRISSON Nicolas]

Hi all,

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 :)

Regards,

Nicolas BRISSON

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?

Thanks,
Brian Rees
