Normal Values of Exposure to Radiation, Limit Values
 
For individuals with professional exposure to radioactive sources in the EU,
there are two legal upper limits:
 
Dose rate limit is 6 mSv p.a. = 3 μSv/h (assuming 2,000 working hours per year), Cat B
Dose rate limit is 20 mSv p.a. = 10 μSv/h (assuming 2,000 working hours per year), Cat A
 
(An exclusion zone exists starting at 3 mSv/h)
The natural environment in Heidelberg, Germany
has a radiation level of about 0.1 - 0.2 μSv/h
