The average radioactive dose a person gets per year is about 3,6 to 5 milliSievert a year (for Belgium) of which 2,6 mSv from natural sources, 0,95mSv from medical examinations and 0,05mSv from industry (of which 0,01mSv due to nuclear power)

So when they say around the reactor the dose in an hour is about the same as you get a year, then this is about equivalent to two scans in a hospital.

Note: this is talking about low levels where the only influence radiation has is increasing the chance of cancer. If there are very high doses >100mSv involved, there will be direct radiological damage which can be strongly compared to damage from burning.
