When you want to visit, you can book a day-trip from Kiev for just $150.
The actual dose rate you receive in this area from external radiation is actually quite low. Measured dose rates around the reactor are around 1.7 µSv per hour. Strange enough the dose rate in the Pripyat amusement park are higher and can run up to 9 µSv per hour. However these dose rates are below the legal threshold for occasional exposure in my country. The main problem is this area is to avoid contamination. Inhalation of respirable radio active dust or swallowing radio active dust is the main problem. As the distance to the source is very close this could generate a quite high dose.
In general the received dose directly after the incident was quite low for most people who were evacuated from the area (< 50 mSv), which is roughly 2.5 times the annual dose a category A radiation worker in allowed to received in my country. A full size body CT scan will vasue a dose already above 20 mSv! >5 Sv (so 100 times higher) is considered to be an immediate lethal dose.
Not very well know is the fact that "only" 31 people died as an immediate result of the accident and fighting the resulting fire (28 from radiation injuries, two from non-radiation blast injuries and one due to a coronary thrombosis), and 134 were diagnosed with acute radiation syndrome. Of the latter, 14 people have since died, but their deaths were not necessarily attributable to radiation exposure (in other words, it couldn't be proven). In addition, about 800 cases of thyroid cancers have been reported in children, of whom three have died. The total of 48 deaths, tragic as it is, has to be compared with the hundreds that die in other natural and man-caused disasters.
It is one of the places I would love to visit during my life. And in case you wonder, yes one of my tasks is radiation safety.

BTW I love the pictures by David Schindler (see Rami's post), they must have been used for the design of the computer game Fall-Out 3!
