Пробежался по ссылкам, там говорится так -
Although the unfortunate death of Mr Litvinenko in London last year stimulated this work, the paper does not examine the particular circumstances of his death.
--------
This paper does not consider the specific radiological circumstances surrounding the tragic death of Mr Litvinenko; rather, it provides an evaluation of published human and animal data and models developed for the estimation of alpha radiation doses from 210Po and the induction of potentially fatal damage to different organs and tissues
----------
The Health Protection Agency can confirm that it is providing expert advice as part of the Metropolitan Police investigations into the death of Alexander Litvinenko.
Tests have established that Mr Litvinenko had a significant quantity of the radioactive isotope Polonium-210 (Po-210) in his body. It is not yet clear how this entered his body. Police are investigating this.

Ходят вокруг да около... Четкого заключения от чего человек умер нет. Единственное что вскольз говорится -
measures that had to be instigated by the Health Protection Agency following the discovery that Mr Litvinenko's death was due to Po-210 poisoning
Но опять же без ссылок на какие-то документы. В общем с фактами негусто, ТАСС здесь не при делах...
. Не надо ребята, британские власти пока даже перед собственным народом не отчитались о том что же произошло. Явно что-то скрывают...
