9B 9A Double lesson Monday Thursday Friday Karin was sick - here is the work that was set:

**Poisoning a spy**...... (Alexander Litvinenko died 2006 poisoned by the alpha source polonium - a highly controversial assassination of a Russian spy)

Polonium 210 is highly radioactive. It is deadly and not easy to detect, in particular as it emits large amounts of alpha radiation which is hard to test for. There were two attempts to poison Litvinenko - the second succeeded. It is though he ingested about 0.000 001g of Polonium 210 which is 200 times the average lethal dose.

Here are facts about polonium-210 (5 mins)

Litvinenko died from multiple organ failure caused by radiation sickness. What is this ?  This video explains(5 mins) @https://www.youtube.com/watch?v=R8rhJlVA3Qc
