text: why does polonium causeshair loss?   plonium is a radiactive element and the same reason is why people going through radio/nuclear-therapie for cancer are loosing their hair (and fell obnociuos).  you have fast growing cells in you body: e.g. stomach-cells ( we are permamently digesting our stoch lining) and hair-cells. this cells have a higher rate of exchange with blood and as all radio-active materials are destryoing the cell membrane of this cells this kills the cells.  i do not want to know how it looked inside this poor guy after 4 days of being poisening by this stuff .....
