Radiation levels as measured at the the plant gate seem to be in the 400 micro-sievert range. That is a level you wouldn't want to live and work in but you could safely pass through it.
the amount of radiation passing through a specific area is inversely proportional to the square of the distance of that area from the energy source. So, using Google earth and its ruler, a very conservative estimate would place the gate 1km from the plant. At 8 km away, you will be facing .0004/(8^2) = .0004/64 = 6.25 micro-sieverts.
Since the only possible gate I see from Google Earth is perhaps 100m from the plant, in this case, the unit of measure becomes meters. 8km = 8000 meters. so, the levels at 8000meters when readings 100m from the plant are 400 micro-sieverts is .0004/(8000^2) = .0004/64,000,000 = 6.25 pico-sieverts - an amount that would be lost in the noise of normal background radiation.
