Przewalskis in the Wormwood zone

It seems that 7000 children have "Chernobyl Heart". 300 may get the operation, the rest will die.
Martin Cruz Smith is in the Zone. Where Pynchon's WWII Zone left off, the Chernobyl Zone resumes. Full of wildlife. Arkady Renko is in the Zone. I dont buy fiction except very occasionally a sf. And any Arkady Renko.

It is said that wolves and boars inhabit the houses. It is also said that the cost of the Wormwood explosion exceeded the combined economic benefit of ALL Soviet nuclear power reactors.
