100 REM (soviet) is in the ballpark. He most likely had some internal dose as anybody in the area at that time did. It ddin't say if he received any medical treatment He didn't die, he got sick. He was well enough to give a report 4 months later and llived another 2 years before ending it all. It wasn't clear what the long term affects of the exposure was. He died one day before he was to give a comprehensive report. Suspicious? The HBO series was dramatized fiction. A lot of truth, but some drama to make it interesting enough to a common audience.
