Unfortunately I was in Gothenburg at the time of the accident and was eating Reindeer as the cloud allegedly passed overhead outlook not good for me............................
I was in Bolton and it improved the pollution levels...Unfortunately I was in Gothenburg at the time of the accident and was eating Reindeer as the cloud allegedly passed overhead outlook not good for me............................
Why do they use the terminology "Roentgens" instead of Sieverts? That's what we learnt at school for doses measured using a Geiger counter. One can only assume it was a legacy standard or very Eastern Bloc?
Film Badge won’t tell you anything until it’s been processed and then it’s too late if you got a dose.
These guys should have been carrying gammacoms - ie the machine that goes blip, blip, blip. We had to collect one and book it out when going on or near the reactors. Give it back after and your dose was recorded against your name. Was all in Microsieverts for us, not Röntgens, never bothered asking what the difference was..
I thought he looked a lot like Richard Harris. Now I know why....Might have been that , it was 20 years ago , my mind might have been fuzzed by Hollywood during that period .
I wish Jared Harris would do more roles like this , I find him fascinating to watch on screen , he brings something special to every role he plays , he was brilliant in mad men , but as I recall met a similar fate .
I remember to go into the more risky parts of the reactor building (the pile cap mainly) we used to go through a machine colloquially called the ‘turnstile’ before togging up. You’d stand in it, stick your hands in a slot, then when it told you turn round, hands on a pad and push back. Tested for contamination (contam). Same on way out. Wish I could remember it’s proper name, didn’t see any on the tv series though.
But he does end up hanging around...Watching episode 1 now, compelling stuff. Prof Legatsov is worried
Just asked one of my ex-colleagues, he said IPM7’s. Don’t remember that...It's a whole body monitor or portal. Siemens used to make them until the business was purchased by Thermo Scientific (american). MGP (french) also make them, plus others.
Following the Chernobyl incident, Siemens (UK) was commissioned to produce a UK monitoring network in case of something similar happening resulting in a cloud of contamination passing over the UK. The system is called RIMNET (Radiation Incident Monitoring NETwork). There are 92 (or more now) monitoring stations dotted around the UK mostly at Met sites, and they gather dose data in the air and pass it to two mirrored databases (one in Poole the other in the DoE building in Westminster). The data is supplemented by other data periodically taken from water and soil samples etc so a complete assessment can be made in real time of the risk of us being exposed to ionising radiation from sources both at home and abroad (like Chernobyl). The system went live in 1990 (or thereabouts) and is still running today.

Pardon my ignorance but my memory from studying is somewhat different.As a result of watching the series do far Phil I decided to read one of the books covering the incident. It explains as follows
"The original unit used to measure radiation exposure was a ROENTGEN, after William Roentgen, who discovered X-rays at the end of the nineteenth century. The amount of radiation to hit the human body is measured in a unit called RAD (radiation absorbed dose) but different types of radiation vary in their biological effects: for example alpha particles are 20 times as damaging as gamma radiation. The unit devised to reflect this is the REM (roentgen equivalent man): for gamma radiation, 1 RAD = 1REM, whilst for alpha radiation 1 RAD = 20 REM. However, new units are now in use. 1 GRAY equals 100 RADS and 1 SIEVERT equals 100 REM.
The becquerel has also replaced the Curie as the measurement of radioactive contamination of soil and food.
So I suppose that the answer to your question is that it is a legacy standard.
I thought that otherwise why give us gammacoms and not alphacoms?!Pardon my ignorance but my memory from studying is somewhat different.
I thought Alpha particles were the weakest and Gamma rays the strongest types of radiation
Alphas are in Smoke Detectors etc and Gamma are in the heavy duty end of industry and hospitals
Have I got this right?
Should have been Q of the day!
May as well watch ep 4 - ep 5 last one not on till next weekWow. It’s really quite horrific and enlightening.
I’m through parts 123 .... the fireman looked like he was liquefying.
I had no idea it was about to go boom until those 3!got rid of the water.
Incredible bravery and sacrifice, with little or no support.
Will watch more tomorrow.

Start early, I was up until 1am watching the first three episodes then had to wait a week for number four , I couldn't turn it offOk, Ill give this a go tonight, looking forward to this!
Ha, yes. IPM7, IPM9, IPCM12...... LOOK HERE if you're interested:Just asked one of my ex-colleagues, he said IPM7’s. Don’t remember that...
