After the worst debris and fallout was cleaned up, a large number of highly radioactive vehicles were left scattered around the Exclusion Zone. They were relocated to a patch of concrete in the middle of the forest, near the town of Buryakivka. This vehicle cemetery features hundreds of vehicles including armoured transport vehicles, diggers, tankers, cranes, bulldozers, and the remains of 8 of the largest Soviet transport helicopters. The most interesting "residents" of the vehicle cemetery are 3 robots used on the roof of reactor 3 to clean up radioactive debris. The most iconic one, the West German "Joker", is contaminated with nuclear fuel particles and remains dangerously radioactive.

Within the 10-km zone is a large former secret radar installation that the Soviet government used to detect missiles, the Duga 3 Radar. From Pripyat, it is easy to see in the distance, if looking from a point of elevation.
A strip of birch and pine forest that was contaminated with the worst fallout, killing off most of the vegetation because of the intense radiation and turning trees reddish brown — hence the name. Trees were felled and buried in trenches by liquidators, then covered over with soil and occasionally concrete slabs.
The Red Forest is still the most radioactive area in the Exclusion Zone, and marked with radiation warning signs but not fenced off in any way. As of 2019, radiation levels vary between 4 µSv/h (microsievert/hour) and 15 µSv/h, with local hot spots reaching 40 µSv/h. Spots where material is buried have considerably higher dose levels. It is recommended to stay no longer than 90 minutes around these hot spots (equivalent to a daily accumulated those of 60 µSv which is the threshold for radiation workers). As the most radioactive outdoor area in Europe, exploring the Red Forest is an experience on its own, but adequate safety measures must be taken. Wear protective wellies, carry an electronic dosimeter (PED) with warning threshold set no higher than 20 µSv/h, and do not touch anything. When leaving the Red Forest, protective wellies must be decontaminated (washed off).
If possible, take a geiger counter or similar radiation measurement device with you into the Red Forest to compare activity levels at different locations. Birch trees and lichen are particularly prone to absorbing radioactive Cesium (accounting to the majority of radiation after 32 years), and often read much higher radiation levels with peaks up to 3,000 counts per second not exceptional. Make sure the probe of the geiger counter does not touch any of the vegetation to avoid contaminating it!
Гейферний ковш
A crane gripper used to remove radioactive debris in the aftermath of the accident. It remains measurably radioactive, and is often cited in popular culture as the most radioactive object in Pripyat city. Because of the natural decay of radioactive isotopes, the claw can nowadays be approached safely but should not be touched to avoid contaminating oneself.
Bridge between Pripyat and the Nuclear Power Plant. According to urban legends, on the night of the accident, people gathered on the bridge to watch the blue glow of ionizing air above the burning reactor, without knowing the dose rate was a deadly 500 R/h. The myth was propagated by journalists and stuck, whereas in reality the dose rate was much lower and no direct casualties were recorded among observers.
МТС (машинно-тракторная станция)
A mechanic workshop where agricultural vehicles were maintained, refurbished, and scrapped for parts before the accident. During the cleanup it was used for the maintenance of vehicles used by liquidators, and the site has been abandoned ever since. Fertilizer machines, corn harvesters, and numerous other agricultural vehicles are now rusting away in a birch forest that is overgrowing them. There is a pick up truck with a trefoil logo on its door, a great place for a souvenir photo. For those interested, there are numerous radiation hot spots in and around the workshop, which can be found with a Geiger counter.
Although radiation detectors (Geiger counters, etc.) tick at many places in the Exclusion Zone, most of the measured activity is very close to natural background levels or slightly above. There are however notable hot spots, where radiation levels are many hundreds or even thousands of times higher than background radiation. If you've never heard a Geiger counter tick, then these are perfect locations to test them out! If you're brave, a good location is this waste separation facility, with radiation levels of ca. 1 mSv/h close to the ground. The radiation is concentrated in an area of about 10 x 10 m. It's recommended to stay no longer than 5 minutes in the area, which should be more than sufficient to make a video recording of a ticking Geiger counter!
