Pripyat, the largest city in the Chernobyl area has relatively low radiation, but some places stand out. In a backyard, there is a gripping claw that was used just after the disaster was a fact.
Used during the first days of the Chernobyl disaster
The gripping claw was used during the first days of the disaster to lift graphite rods in the destroyed nuclear power plant. A rapid measurement of one leaf of the clone shows 200-350 microsievert (0.2-0.35 millisievert) per hour. Staff working in places where radiation occurs are allowed 50 microsieverts per year. A dental X-ray corresponds to 0.01 millisievert.
Immediate radiation poisoning?
Thus, there is nothing that gives you an immediate radiation poisoning, but to spend some longer time with claw is nothing to recommend. Have a seat in the claw would correspond to a dose of 3000 times the normal background radiation. And there are people who did it. Crawling into the claw does not just give a radiation dose while sitting there, but strong radioactive particles will get caught in hair and clothing that will give a much longer exposure.
Apart from this place, it is, what I know, only the basement at the Pripyat Hospital that has a higher radiation dose in the now abandoned city of Pripyat.
