Litvinenko poisoning puzzle

Scottish high school students have been asked to examine the notorious death of the former Russian secret services officer Alexander Litvinenko in their chemistry exam.

Litvinenko was poisoned in the UK in 2006, by a fatal dose of Polonium-210.

According to the Sun tabloid, up to 10,000 school children had to give their reasons as to why the risk of the highly radioactive substance Polonium-210 in his body was ‘insignificant’ to the general public.

The largest organization for advancing the chemical sciences in Europe, the Royal Society of Chemistry, was quoted as saying that Litvinenko’s case was a ‘great way of illustrating science’.
