I'm not a physicist.
1 cm3 or 0.1 cm3 - is there any difference?
What about 0.00...01 cm3 - can it do with tea something like this tale?
As I know, sofa on which Alexander was sat , was affected by radiation, too, and was cleaned in special way, Berezovsky told about it.
Just open the container and entire room will be contaminated with the aerosol of polonium compounds.
Do you know about such way, ampoule ?

- just drop such ampoule into cup of tea. Will room be affected?
