As someone that works in the nuclear industry in the UK, we're taught about the effects of criticality incidents and accidents. Having been born in 1971, I was in secondary school in 1986 when this happened, so already knew a fair bit about it from stuff I'd learned over the years. I can honestly say that this series has sparked numerous conversations at work and talking with the "experts" this is about as accurate a depiction of the effects on the human body, from radiation, as you're ever likely to see. And to some extent, it's still been "dumbed down" to make it easier viewing... The 1980's Soviet Union, and their distrust of EVERYONE is scarily portrayed. Ignore the British, northern accents of the large majority of the actors, and instead, watch one of the most horrific, scary, stories, unfold. And never forget, this is a TRUE story; this REALLY HAPPENED! It has opened the eyes of some of the trainees we have to the dangers of working with radioactive substances - one of the most dangerous substances known to man. Enjoy!!
