Chernobyl (HBO Mini Series)
Discussion
Also, dont know where they filmed the control room, but it is quite good, apart from the big computer screens on the back panel.
Remember looking at the core map and asking what was in a few channels with odd labels, to be told "Special scientific purposes"
Probably tritium canisters for hydrogen bombs.
Was a great placement from work
We had a KGB minder, drank all day, but at least he offered us some.

Worth reading up on the Goiânia accident as well. The main individual received a dose of 800 roentgens but survived whereas others with much lower doses died. This seems to be similar to Chernobyl where some survived doses far in excess of that deemed fatal but others succumbed to lower exposures.
There are so many factors involved that it makes estimating a fatal level very difficult. It really depends on how the exposure occurs. In general, if it is external then it may be bad but survivable. Internal (mostly through inhalation) then not much can be done.
Which is why we use the Sievert, it has qualitive factors taken into account such that it accounts for the difference in how its taken up and given in effective dose or committed dose for ingested dose.There are so many factors involved that it makes estimating a fatal level very difficult. It really depends on how the exposure occurs. In general, if it is external then it may be bad but survivable. Internal (mostly through inhalation) then not much can be done.
Even then we have different dose limits for the lens of the eye to whats allowed for whole body dose.
I had a lifetime dose of 6mSv until I went to Smolensk RBMK. Managed to double it in a week.
However, the Sievert is only really effective for low doses, big doses are still measured in Grays which is a measure of the actual energy absorbed and at high energy's its a good measure of the actual damage to the cells.
Been about 20 years since I did my Senior Authorised Persons Nuclear Radiations training, but I still have my authorisation.
"Sievert Stan" stuck for a while!
The lifetime doses we get in the UK are miniscule compared to historic doses abroad.
Mind you, still a few weeks ago felt a flash around me and noted no criticality alarm active and my first thought was "can't be a criticality, can it, nose hair isn't burning" and then I remembered a) I was in my kitchen not on a reprocessing plant and b) it was a thunder and lightening storm outside.
One of our staff at the old place was on R3 the night R4 went up. Whenever you asked him what we could learn from the incident he would say "never call a Ukrainian Russian" and then clam up.

Ha-ha in 25 years in the industry I managed only 1/10th that dose, Gary C; and then doubled it at Dungeness (A). What I couldn't work out for a bit was why my colleague and RPA was always getting lower doses than me.....he eventually owned up, as well as "time, distance and shielding" to reduce his dose, he always tried to stand behind the fattest person in the group, which was me!

Don't forget the A of RPA is adviser: we're not there to do the work or get the dose! I've often said to people that if they were ever in doubt of where was a good/bad place to stand, see where the RPA is; we generally hunt out the lower dose rates for a chat! We do have some interesting lifetime doses in the UK: I've seen 200+ mSv on dose records, but mostly front loaded to the 'old days', current doses in most places are actually pretty good, even Chernobyl.... unless they cheat (which some do)."Sievert Stan" stuck for a while!

The nuclear accident story that really got to me was a guy named Hisashi Ouchi, victim of an accident at a Japanese power plant. I think his is meant to be the highest level of radiation exposure a human has ever experienced: https://www.reddit.com/user/willowoftheriver/comme...
Ouchi's was nasty because he was conscious for a while and they kept him alive for a long time. I doubt he's the highest ever though - the dude in the Sarov criticality accident died more or less immediately and got something like 50Gy. The guys in the room with the SL1 experimental reactor probably got massive doses too but were finished off by bits of exploding reactor rather than radiation.llewop said:

However, as I work in an AGR, the doses are lower than any other Nuclear Powerstation I know about. No fuel failures, no active feedwater circuit.
Even vessel entry has a lower dose than most

Looking those up.Sarov incident he took three days to die.
Wood river incident the man was exposed to 100Gy and died 49 hours later.

What the hell is this 1980? When is the next episode?
Sky doesn’t say
Same time each week, Tuesdays at 9pm, it's on the EPG.Sky doesn’t say
Totally coincidentally, I'm reading this just now - https://www.amazon.co.uk/Chernobyl-History-Tragedy... - it follows Ep1 pretty much exactly though it's pretty slow going with lots of background scene setting rather than just a straight account of the accident and aftermath. The explanation of what actually happened is the most detailed I've read though.
Just watched the first episode. Was ok actually.
Not sure how close this is to what actually happened.
I know it's morbid, but I did like the scene where the woman witnesses the explosion through her window. Quite haunting really.
Then you see the light emerging from the blown reactor.
The whole thing was an absolute mess and loads of the poor buggers didn't know what they were being exposed to.

I enjoyed the first episode. When I saw the fireman's wife watch the explosion I did think that If I lived close to a nuclear power plant and I witnessed an explosion I'd be looking for my car keys pretty sharpish. Not sure how close this is to what actually happened.

When Chernobyl happened / became known about I was off work on holiday.
I returned to my shared house in Cockermouth and by then there was starting to be some news and excitement. One of my housemates at Sellafield was telling me how the alarms had gone off at Sellafield as the fallout cloud passed and another (whom I think was a Health Physics / RPS / RPA) telling me about the emeerging knowledge of the cloud passing Sweden et al.
Guess whom had just spent a week backpacking and wild camping the Pennine Way North from Dufton to Kirk Yetholm, drinking much stream water off the moors on the way!!!!!!
Is this on Virgin, can't find HBO on my set-up.

I was out hiking in the North Wales mountains that day and the day it specifically started to rain got soaked...
Also you have to get for the skiers who go to the Alpes so many of the resorts were dark red coverage

Not sure - it's academic beyond a certain point as you're dead regardless. If you're interested in nuclear accidents the various IAEA accident reports make for a good read. They're obviously a bit dry but fascinating if you're into the detail of what can go wrong.
welcome to my world!I have been scanning through a HPA (Health Protection Agency - now Public Health England and previously NRPB) report on acute exposures; in gist:
LD50 - lethal dose for 50% of those exposed: 3.5 - 5.5 Gy (Gray and Sievert are essentially the same if we're talking external exposures such as X-ray/gamma)
beyond that up to around 10 Gy: death probable (without treatment), higher the exposure, the quicker it is likely to be
beyond 10 Gy: death certain (without treatment) might take a couple of weeks at 10 Gy, couple of days when you get beyond 30 Gy.
I do worry (to be vaguely relevant to the programme....) that they'll end up over egging the radiation casualties/potential head count or have some 'interesting' interpretations of exposures/risks and outcomes.
