Isn’t this an area where Rolls-Royce is building nuclear submarine engines?
Maybe it is someone who works on a nuclear submarine who measures the radiation of his laundry? It’s not funny i know, these levels can’t be healthy.
I hope the person who set up this monitor can give us some information of what is causing these levels.
Is there a way to add notes nest to the data? or to blocks of data?
Something like selecting a spike and add a note that explains the data.
In the long run then you have a memory of some events that can help to explain other events.
